    /**
      A `DS.InvalidError` is used by an adapter to signal the external API
      was unable to process a request because the content was not
      semantically correct or meaningful per the API. Usually this means a
      record failed some form of server side validation. When a promise
      from an adapter is rejected with a `DS.InvalidError` the record will
      transition to the `invalid` state and the errors will be set to the
      `errors` property on the record.

      For Ember Data to correctly map errors to their corresponding
      properties on the model, Ember Data expects each error to be
      namespaced under a key that matches the property name. For example
      if you had a Post model that looked like this.

      ```js
      App.Post = DS.Model.extend({
        title: DS.attr('string'),
        content: DS.attr('string')
      });
      ```

      To show an error from the server related to the `title` and
      `content` properties your adapter could return a promise that
      rejects with a `DS.InvalidError` object that looks like this:

      ```js
      App.PostAdapter = DS.RESTAdapter.extend({
        updateRecord: function() {
          // Fictional adapter that always rejects
          return Ember.RSVP.reject(new DS.InvalidError({
            title: ['Must be unique'],
            content: ['Must not be blank'],
          }));
        }
      });
      ```

      Your backend may use different property names for your records the
      store will attempt extract and normalize the errors using the
      serializer's `extractErrors` method before the errors get added to
      the the model. As a result, it is safe for the `InvalidError` to
      wrap the error payload unaltered.

      Example

      ```javascript
      App.ApplicationAdapter = DS.RESTAdapter.extend({
        ajaxError: function(jqXHR) {
          var error = this._super(jqXHR);

          // 422 is used by this fictional server to signal a validation error
          if (jqXHR && jqXHR.status === 422) {
            var jsonErrors = Ember.$.parseJSON(jqXHR.responseText);
            return new DS.InvalidError(jsonErrors);
          } else {
            // The ajax request failed however it is not a result of this
            // record being in an invalid state so we do not return a
            // `InvalidError` object.
            return error;
          }
        }
      });
      ```

      @class InvalidError
      @namespace DS
    */
    function ember$data$lib$system$adapter$$InvalidError(errors) {
      var tmp = Error.prototype.constructor.call(this, "The backend rejected the commit because it was invalid: " + Ember.inspect(errors));
      this.errors = errors;

      for (var i=0, l=ember$data$lib$system$adapter$$errorProps.length; i<l; i++) {
        this[ember$data$lib$system$adapter$$errorProps[i]] = tmp[ember$data$lib$system$adapter$$errorProps[i]];
      }
    }

    ember$data$lib$system$adapter$$InvalidError.prototype = Ember.create(Error.prototype);

    /**
      An adapter is an object that receives requests from a store and
      translates them into the appropriate action to take against your
      persistence layer. The persistence layer is usually an HTTP API, but
      may be anything, such as the browser's local storage. Typically the
      adapter is not invoked directly instead its functionality is accessed
      through the `store`.

      ### Creating an Adapter

      Create a new subclass of `DS.Adapter`, then assign
      it to the `ApplicationAdapter` property of the application.

      ```javascript
      var MyAdapter = DS.Adapter.extend({
        // ...your code here
      });

      App.ApplicationAdapter = MyAdapter;
      ```

      Model-specific adapters can be created by assigning your adapter
      class to the `ModelName` + `Adapter` property of the application.

      ```javascript
      var MyPostAdapter = DS.Adapter.extend({
        // ...Post-specific adapter code goes here
      });

      App.PostAdapter = MyPostAdapter;
      ```

      `DS.Adapter` is an abstract base class that you should override in your
      application to customize it for your backend. The minimum set of methods
      that you should implement is:

        * `find()`
        * `createRecord()`
        * `updateRecord()`
        * `deleteRecord()`
        * `findAll()`
        * `findQuery()`

      To improve the network performance of your application, you can optimize
      your adapter by overriding these lower-level methods:

        * `findMany()`


      For an example implementation, see `DS.RESTAdapter`, the
      included REST adapter.

      @class Adapter
      @namespace DS
      @extends Ember.Object

    var ember$data$lib$system$adapter$$Adapter = Ember.Object.extend({

      /**
        If you would like your adapter to use a custom serializer you can
        set the `defaultSerializer` property to be the name of the custom
        serializer.

        Note the `defaultSerializer` serializer has a lower priority than
        a model specific serializer (i.e. `PostSerializer`) or the
        `application` serializer.

        ```javascript
        var DjangoAdapter = DS.Adapter.extend({
          defaultSerializer: 'django'
        });
        ```

        @property defaultSerializer

        The `find()` method is invoked when the store is asked for a record that
        has not previously been loaded. In response to `find()` being called, you

        found, you can asynchronously call the store's `push()` method to push
        the record into the store.

    });

    var ember$data$lib$adapters$rest$adapter$$get = Ember.get;
    var ember$data$lib$adapters$rest$adapter$$forEach = Ember.ArrayPolyfills.forEach;

    var ember$data$lib$adapters$rest$adapter$$default = ember$data$lib$system$adapter$$Adapter.extend(ember$data$lib$adapters$build$url$mixin$$default, {
      defaultSerializer: '-rest',

      /**
        By default, the RESTAdapter will send the query params sorted alphabetically to the
        server.

        For example:

        ```js
          store.find('posts', {sort: 'price', category: 'pets'});
        ```

        will generate a requests like this `/posts?category=pets&sort=price`, even if the
        parameters were specified in a different order.

        That way the generated URL will be deterministic and that simplifies caching mechanisms
        in the backend.

        Setting `sortQueryParams` to a falsey value will respect the original order.

        In case you want to sort the query parameters with a different criteria, set
        `sortQueryParams` to your custom sort function.

        ```js
        export default DS.RESTAdapter.extend({
          sortQueryParams: function(params) {
            var sortedKeys = Object.keys(params).sort().reverse();
            var len = sortedKeys.length, newParams = {};

            for (var i = 0; i < len; i++) {
              newParams[sortedKeys[i]] = params[sortedKeys[i]];
            }
            return newParams;
          }
        });
        ```

        @method sortQueryParams
        @param {Object} obj
        @return {Object}
      */
      sortQueryParams: function(obj) {
        var keys = Ember.keys(obj);
        var len = keys.length;
        if (len < 2) {
          return obj;
        }
        var newQueryParams = {};
        var sortedKeys = keys.sort();

        for (var i = 0; i < len; i++) {
          newQueryParams[sortedKeys[i]] = obj[sortedKeys[i]];
        }
        return newQueryParams;
      },

      /**
        By default the RESTAdapter will send each find request coming from a `store.find`
        or from accessing a relationship separately to the server. If your server supports passing
        ids as a query string, you can set coalesceFindRequests to true to coalesce all find requests
        within a single runloop.

        For example, if you have an initial payload of:

        ```javascript
        {
          post: {
            id: 1,
            comments: [1, 2]
          }
        }
        ```

        By default calling `post.get('comments')` will trigger the following requests(assuming the
        comments haven't been loaded before):

        ```
        GET /comments/1
        GET /comments/2
        ```

        If you set coalesceFindRequests to `true` it will instead trigger the following request:

        ```
        GET /comments?ids[]=1&ids[]=2
        ```

        Setting coalesceFindRequests to `true` also works for `store.find` requests and `belongsTo`
        relationships accessed within the same runloop. If you set `coalesceFindRequests: true`

        ```javascript
        store.find('comment', 1);
        store.find('comment', 2);
        ```

        will also send a request to: `GET /comments?ids[]=1&ids[]=2`

        Note: Requests coalescing rely on URL building strategy. So if you override `buildURL` in your app
        `groupRecordsForFindMany` more likely should be overridden as well in order for coalescing to work.

        @type {boolean}

        This implementation groups together records that have the same base URL but

        because we know findMany can coalesce them together as `/comments?ids[]=1&ids[]=2`

        but not those where there is more than 1 query param such as `/comments?id=2&name=David`
        Currently only the query param of `id` is supported. If you need to support others, please
        override this or the `_stripIDFromURL` method.

      /**
        Takes an ajax response, and returns an error payload.

        Returning a `DS.InvalidError` from this method will cause the
        record to transition into the `invalid` state and make the
        `errors` object available on the record. When returning an
        `InvalidError` the store will attempt to normalize the error data
        returned from the server using the serializer's `extractErrors`
        method.

        Example

        ```javascript
        App.ApplicationAdapter = DS.RESTAdapter.extend({
          ajaxError: function(jqXHR) {
            var error = this._super(jqXHR);

            if (jqXHR && jqXHR.status === 422) {
              var jsonErrors = Ember.$.parseJSON(jqXHR.responseText);

              return new DS.InvalidError(jsonErrors);
            } else {
              return error;
            }
          }
        });
        ```

        Note: As a correctness optimization, the default implementation of
        the `ajaxError` method strips out the `then` method from jquery's
        ajax response (jqXHR). This is important because the jqXHR's
        `then` method fulfills the promise with itself resulting in a
        circular "thenable" chain which may cause problems for some
        promise libraries.

        @method ajaxError
        @param  {Object} jqXHR
        @param  {Object} responseText
        @param  {Object} errorThrown
        @return {Object} jqXHR
      */

        You might want to override it in two cases:

        1. Your API might return useful results in the request headers.
        If you need to access these, you can override this hook to copy them
        from jqXHR to the payload object so they can be processed in you serializer.

        2. Your API might return errors as successful responses with status code
        200 and an Errors text or object. You can return a DS.InvalidError from
        this hook and it will automatically reject the promise and put your record
        into the invalid state.

        By default, `ajax` method has the following behavior:

        * It sets the response `dataType` to `"json"`

      Inflector.Ember provides a mechanism for supplying inflection rules for your

      API for providing additional rules.

      Examples:

      Creating an inflector with no rules.

      ```js
      var inflector = new Ember.Inflector();
      ```

      Creating an inflector with the default ember ruleset.

      ```js
      var inflector = new Ember.Inflector(Ember.Inflector.defaultRules);

      inflector.pluralize('cow'); //=> 'kine'
      inflector.singularize('kine'); //=> 'cow'
      ```

      Creating an inflector and adding rules later.

      ```javascript
      var inflector = Ember.Inflector.inflector;

      inflector.pluralize('advice'); // => 'advices'
      inflector.uncountable('advice');
      inflector.pluralize('advice'); // => 'advice'

      inflector.pluralize('formula'); // => 'formulas'
      inflector.irregular('formula', 'formulae');
      inflector.pluralize('formula'); // => 'formulae'

      // you would not need to add these as they are the default rules
      inflector.plural(/$/, 's');
      inflector.singular(/s$/i, '');
      ```

    /**
      The ActiveModelAdapter is a subclass of the RESTAdapter designed to integrate
      with a JSON API that uses an underscored naming convention instead of camelCasing.
      It has been designed to work out of the box with the
      [active\_model\_serializers](https://github.com/rails-api/active_model_serializers)
      Ruby gem. This Adapter expects specific settings using ActiveModel::Serializers,
      `embed :ids, embed_in_root: true` which sideloads the records.

      This adapter extends the DS.RESTAdapter by making consistent use of the camelization,
      decamelization and pluralization methods to normalize the serialized JSON into a
      format that is compatible with a conventional Rails backend and Ember Data.

      ## JSON Structure

      The ActiveModelAdapter expects the JSON returned from your server to follow
      the REST adapter conventions substituting underscored keys for camelcased ones.

      Unlike the DS.RESTAdapter, async relationship keys must be the singular form
      of the relationship name, followed by "_id" for DS.belongsTo relationships,
      or "_ids" for DS.hasMany relationships.

      ### Conventional Names

      Attribute names in your JSON payload should be the underscored versions of
      the attributes in your Ember.js models.

      For example, if you have a `Person` model:

      ```js
      App.FamousPerson = DS.Model.extend({
        firstName: DS.attr('string'),
        lastName: DS.attr('string'),
        occupation: DS.attr('string')
      });
      ```

      The JSON returned should look like this:

      ```js
      {
        "famous_person": {
          "id": 1,
          "first_name": "Barack",
          "last_name": "Obama",
          "occupation": "President"
        }
      }
      ```

      Let's imagine that `Occupation` is just another model:

      ```js
      App.Person = DS.Model.extend({
        firstName: DS.attr('string'),
        lastName: DS.attr('string'),
        occupation: DS.belongsTo('occupation')
      });

      App.Occupation = DS.Model.extend({
        name: DS.attr('string'),
        salary: DS.attr('number'),
        people: DS.hasMany('person')
      });
      ```

      The JSON needed to avoid extra server calls, should look like this:

      ```js
      {
        "people": [{
          "id": 1,
          "first_name": "Barack",
          "last_name": "Obama",
          "occupation_id": 1
        }],

        "occupations": [{
          "id": 1,
          "name": "President",
          "salary": 100000,
          "person_ids": [1]
        }]
      }
      ```

        convention. In these cases it is useful to override the
        primaryKey property to match the primaryKey of your external

        property `key` can also be used to designate the attribute's key on
        the response payload.

        Example

        ```javascript
        App.Person = DS.Model.extend({
          firstName: DS.attr('string'),

        });
        ```

        You can also remove attributes by setting the `serialize` key to
        false in your mapping object.

      // SERIALIZE
      /**
        Called when a record is saved in order to convert the
        record into JSON.

        By default, it creates a JSON object with a key for
        each attribute and belongsTo relationship.

        For example, consider this model:

        ```javascript
        App.Comment = DS.Model.extend({
          title: DS.attr(),
          body: DS.attr(),

          author: DS.belongsTo('user')
        });
        ```

        The default serialization would create a JSON object like:

        ```javascript
        {
          "title": "Rails is unagi",
          "body": "Rails? Omakase? O_O",
          "author": 12
        }
        ```

        By default, attributes are passed through as-is, unless
        you specified an attribute type (`DS.attr('date')`). If
        you specify a transform, the JavaScript value will be
        serialized when inserted into the JSON hash.

        By default, belongs-to relationships are converted into
        IDs when inserted into the JSON hash.

        ## IDs

        `serialize` takes an options hash with a single option:
        `includeId`. If this option is `true`, `serialize` will,
        by default include the ID in the JSON object it builds.

        The adapter passes in `includeId: true` when serializing
        a record for `createRecord`, but not for `updateRecord`.

        ## Customization

        Your server may expect a different JSON format than the
        built-in serialization format.

        In that case, you can implement `serialize` yourself and
        return a JSON hash of your choosing.

        ```javascript
        App.PostSerializer = DS.JSONSerializer.extend({
          serialize: function(snapshot, options) {
            var json = {
              POST_TTL: snapshot.attr('title'),
              POST_BDY: snapshot.attr('body'),
              POST_CMS: snapshot.hasMany('comments', { ids: true })
            }

            if (options.includeId) {
              json.POST_ID_ = snapshot.id;
            }

            return json;
          }
        });
        ```

        ## Customizing an App-Wide Serializer

        If you want to define a serializer for your entire
        application, you'll probably want to use `eachAttribute`
        and `eachRelationship` on the record.

        ```javascript
        App.ApplicationSerializer = DS.JSONSerializer.extend({
          serialize: function(snapshot, options) {
            var json = {};

            snapshot.eachAttribute(function(name) {
              json[serverAttributeName(name)] = snapshot.attr(name);
            })

            snapshot.eachRelationship(function(name, relationship) {
              if (relationship.kind === 'hasMany') {
                json[serverHasManyName(name)] = snapshot.hasMany(name, { ids: true });
              }
            });

            if (options.includeId) {
              json.ID_ = snapshot.id;
            }

            return json;
          }
        });

        function serverAttributeName(attribute) {
          return attribute.underscore().toUpperCase();
        }

        function serverHasManyName(name) {
          return serverAttributeName(name.singularize()) + "_IDS";
        }
        ```

        This serializer will generate JSON that looks like this:

        ```javascript
        {
          "TITLE": "Rails is omakase",
          "BODY": "Yep. Omakase.",
          "COMMENT_IDS": [ 1, 2, 3 ]
        }
        ```

        ## Tweaking the Default JSON

        If you just want to do some small tweaks on the default JSON,
        you can call super first and make the tweaks on the returned
        JSON.

        ```javascript
        App.PostSerializer = DS.JSONSerializer.extend({
          serialize: function(snapshot, options) {
            var json = this._super.apply(this, arguments);

            json.subject = json.title;
            delete json.title;

            return json;
          }
        });
        ```

        @method serialize
        @param {DS.Snapshot} snapshot
        @param {Object} options
        @return {Object} json
      */
      serialize: function(snapshot, options) {
        var json = {};

        if (options && options.includeId) {
          var id = snapshot.id;

          if (id) {
            json[ember$data$lib$serializers$json$serializer$$get(this, 'primaryKey')] = id;
          }
        }

        snapshot.eachAttribute(function(key, attribute) {
          this.serializeAttribute(snapshot, json, key, attribute);
        }, this);

        snapshot.eachRelationship(function(key, relationship) {
          if (relationship.kind === 'belongsTo') {
            this.serializeBelongsTo(snapshot, json, relationship);
          } else if (relationship.kind === 'hasMany') {
            this.serializeHasMany(snapshot, json, relationship);
          }
        }, this);

        return json;
      },

      // EXTRACT

      /**
        The `extract` method is used to deserialize payload data from the
        server. By default the `JSONSerializer` does not push the records
        into the store. However records that subclass `JSONSerializer`
        such as the `RESTSerializer` may push records into the store as
        part of the extract call.

        This method delegates to a more specific extract method based on
        the `requestType`.

        To override this method with a custom one, make sure to call
        `return this._super(store, type, payload, id, requestType)` with your
        pre-processed data.

        Here's an example of using `extract` manually:

          var data = message.data;
          var type = store.modelFor(message.modelName);
          var serializer = store.serializerFor(type.typeKey);
          var record = serializer.extract(store, type, data, data.id, 'single');

          store.push(message.modelName, record);

    /**
      Normally, applications will use the `RESTSerializer` by implementing
      the `normalize` method and individual normalizations under
      `normalizeHash`.

      This allows you to do whatever kind of munging you need, and is
      especially useful if your server is inconsistent and you need to
      do munging differently for many different kinds of responses.

      See the `normalize` documentation for more information.

      ## Across the Board Normalization

      There are also a number of hooks that you might find useful to define
      across-the-board rules for your payload. These rules will be useful
      if your server is consistent, or if you're building an adapter for
      an infrastructure service, like Parse, and want to encode service
      conventions.

      For example, if all of your keys are underscored and all-caps, but
      otherwise consistent with the names you use in your models, you
      can implement across-the-board rules for how to convert an attribute
      name in your model to a key in your JSON.

      ```js
      App.ApplicationSerializer = DS.RESTSerializer.extend({
        keyForAttribute: function(attr) {
          return Ember.String.underscore(attr).toUpperCase();
        }
      });
      ```

      You can also implement `keyForRelationship`, which takes the name
      of the relationship as the first parameter, and the kind of
      relationship (`hasMany` or `belongsTo`) as the second parameter.

            "_id": 2,
            "body": "Rails is unagi"
          }]
        }
        ```

        You use `normalizeHash` to normalize just the comments:

        ```javascript
        App.PostSerializer = DS.RESTSerializer.extend({
          normalizeHash: {
            comments: function(hash) {
              hash.id = hash._id;
              delete hash._id;
              return hash;
            }
          }
        });
        ```

        The key under `normalizeHash` is usually just the original key
        that was in the original payload. However, key names will be
        impacted by any modifications done in the `normalizePayload`
        method. The `DS.RESTSerializer`'s default implementation makes no
        changes to the payload keys.

        @property normalizeHash
        @type {Object}
        @default undefined
      */

      /**
        Normalizes a part of the JSON payload returned by
        the server. You should override this method, munge the hash
        and call super if you have generic normalization to do.

        It takes the type of the record that is being normalized
        (as a DS.Model class), the property where the hash was
        originally found, and the hash to normalize.

        For example, if you have a payload that looks like this:

        ```js
        {
          "post": {
            "id": 1,
            "title": "Rails is omakase",
            "comments": [ 1, 2 ]
          },
          "comments": [{
            "id": 1,
            "body": "FIRST"
          }, {
            "id": 2,
            "body": "Rails is unagi"
          }]
        }
        ```

        The `normalize` method will be called three times:

        * With `App.Post`, `"posts"` and `{ id: 1, title: "Rails is omakase", ... }`
        * With `App.Comment`, `"comments"` and `{ id: 1, body: "FIRST" }`
        * With `App.Comment`, `"comments"` and `{ id: 2, body: "Rails is unagi" }`

        You can use this method, for example, to normalize underscored keys to camelized
        or other general-purpose normalizations.

        If you want to do normalizations specific to some part of the payload, you
        can specify those under `normalizeHash`.

        For example, if the `IDs` under `"comments"` are provided as `_id` instead of
        `id`, you can specify how to normalize just the comments:

        ```js
        App.PostSerializer = DS.RESTSerializer.extend({
          normalizeHash: {
            comments: function(hash) {
              hash.id = hash._id;
              delete hash._id;
              return hash;
            }
          }
        });
        ```

        The key under `normalizeHash` is just the original key that was in the original
        payload.

        @method normalize
        @param {subclass of DS.Model} type
        @param {Object} hash
        @param {String} prop
        @return {Object}
      */
      normalize: function(type, hash, prop) {
        this.normalizeId(hash);
        this.normalizeAttributes(type, hash);
        this.normalizeRelationships(type, hash);

        this.normalizeUsingDeclaredMapping(type, hash);

        if (this.normalizeHash && this.normalizeHash[prop]) {
          this.normalizeHash[prop](hash);
        }

        this.applyTransforms(type, hash);
        return hash;
      },


      /**
        Called when the server has returned a payload representing
        a single record, such as in response to a `find` or `save`.

        It is your opportunity to clean up the server's response into the normalized
        form expected by Ember Data.

        If you want, you can just restructure the top-level of your payload, and
        do more fine-grained normalization in the `normalize` method.

        For example, if you have a payload like this in response to a request for
        post 1:

        ```js
        {
          "id": 1,
          "title": "Rails is omakase",

          "_embedded": {
            "comment": [{
              "_id": 1,
              "comment_title": "FIRST"
            }, {
              "_id": 2,
              "comment_title": "Rails is unagi"
            }]
          }
        }
        ```

        You could implement a serializer that looks like this to get your payload
        into shape:

        ```js
        App.PostSerializer = DS.RESTSerializer.extend({
          // First, restructure the top-level so it's organized by type
          extractSingle: function(store, type, payload, id) {
            var comments = payload._embedded.comment;
            delete payload._embedded;

            payload = { comments: comments, post: payload };
            return this._super(store, type, payload, id);
          },

          normalizeHash: {
            // Next, normalize individual comments, which (after `extract`)
            // are now located under `comments`
            comments: function(hash) {
              hash.id = hash._id;
              hash.title = hash.comment_title;
              delete hash._id;
              delete hash.comment_title;
              return hash;
            }
          }
        })
        ```

        When you call super from your own implementation of `extractSingle`, the
        built-in implementation will find the primary record in your normalized
        payload and push the remaining records into the store.

        The primary record is the single hash found under `post` or the first
        element of the `posts` array.

        The primary record has special meaning when the record is being created
        for the first time or updated (`createRecord` or `updateRecord`). In
        particular, it will update the properties of the record that was saved.

        @method extractSingle

            }]
          }
        }
        ```

        You could implement a serializer that looks like this to get your payload
        into shape:

        ```js
        App.PostSerializer = DS.RESTSerializer.extend({
          // First, restructure the top-level so it's organized by type

          extractArray: function(store, type, payload) {
            var posts = payload._embedded.post;

            posts.forEach(function(post) {
              post.comments = [];
              postCache[post.id] = post;

        ```

        When you call super from your own implementation of `extractArray`, the
        built-in implementation will find the primary array in your normalized
        payload and push the remaining records into the store.

        The primary array is the array found under `posts`.

        The primary record has special meaning when responding to `findQuery`
        or `findHasMany`. In particular, the primary array will become the
        list of records in the record array that kicked off the request.

        If your primary array contains secondary (embedded) records of the same type,
        you cannot place these into the primary array `posts`. Instead, place the
        secondary items into an underscore prefixed property `_posts`, which will
        push these items into the store and will not affect the resulting query.

        This method is used to convert each JSON root key in the payload
        into a typeKey that it can use to look up the appropriate model for
        that part of the payload. By default the typeKey for a model is its
        name in camelCase, so if your JSON root key is 'fast-car' you would
        use typeForRoot to convert it to 'fastCar' so that Ember Data finds
        the `FastCar` model.

        If you diverge from this norm you should also consider changes to
        store._normalizeTypeKey as well.

        For example, your server may return prefixed root keys like so:

        ```js
        {
          "response-fast-car": {
            "id": "1",
            "name": "corvette"
          }
        }
        ```

        In order for Ember Data to know that the model corresponding to
        the 'response-fast-car' hash is `FastCar` (typeKey: 'fastCar'),
        you can override typeForRoot to convert 'response-fast-car' to
        'fastCar' like so:

        ```js
        App.ApplicationSerializer = DS.RESTSerializer.extend({
          typeForRoot: function(root) {
            // 'response-fast-car' should become 'fast-car'
            var subRoot = root.substring(9);

            // _super normalizes 'fast-car' to 'fastCar'
            return this._super(subRoot);
          }
        });
        ```

      */
      typeForRoot: function(key) {
        return ember$data$lib$serializers$rest$serializer$$camelize(ember$inflector$lib$lib$system$string$$singularize(key));
      },

      // SERIALIZE

      /**
        Called when a record is saved in order to convert the
        record into JSON.

        By default, it creates a JSON object with a key for
        each attribute and belongsTo relationship.

        For example, consider this model:

        ```js
        App.Comment = DS.Model.extend({
          title: DS.attr(),
          body: DS.attr(),

          author: DS.belongsTo('user')
        });
        ```

        The default serialization would create a JSON object like:

        ```js
        {
          "title": "Rails is unagi",
          "body": "Rails? Omakase? O_O",
          "author": 12
        }
        ```

        By default, attributes are passed through as-is, unless
        you specified an attribute type (`DS.attr('date')`). If
        you specify a transform, the JavaScript value will be
        serialized when inserted into the JSON hash.

        By default, belongs-to relationships are converted into
        IDs when inserted into the JSON hash.

        ## IDs

        `serialize` takes an options hash with a single option:
        `includeId`. If this option is `true`, `serialize` will,
        by default include the ID in the JSON object it builds.

        The adapter passes in `includeId: true` when serializing
        a record for `createRecord`, but not for `updateRecord`.

        ## Customization

        Your server may expect a different JSON format than the
        built-in serialization format.

        In that case, you can implement `serialize` yourself and
        return a JSON hash of your choosing.

        ```js
        App.PostSerializer = DS.RESTSerializer.extend({
          serialize: function(snapshot, options) {
            var json = {
              POST_TTL: snapshot.attr('title'),
              POST_BDY: snapshot.attr('body'),
              POST_CMS: snapshot.hasMany('comments', { ids: true })
            }

            if (options.includeId) {
              json.POST_ID_ = snapshot.id;
            }

            return json;
          }
        });
        ```

        ## Customizing an App-Wide Serializer

        If you want to define a serializer for your entire
        application, you'll probably want to use `eachAttribute`
        and `eachRelationship` on the record.

        ```js
        App.ApplicationSerializer = DS.RESTSerializer.extend({
          serialize: function(snapshot, options) {
            var json = {};

            snapshot.eachAttribute(function(name) {
              json[serverAttributeName(name)] = snapshot.attr(name);
            })

            snapshot.eachRelationship(function(name, relationship) {
              if (relationship.kind === 'hasMany') {
                json[serverHasManyName(name)] = snapshot.hasMany(name, { ids: true });
              }
            });

            if (options.includeId) {
              json.ID_ = snapshot.id;
            }

            return json;
          }
        });

        function serverAttributeName(attribute) {
          return attribute.underscore().toUpperCase();
        }

        function serverHasManyName(name) {
          return serverAttributeName(name.singularize()) + "_IDS";
        }
        ```

        This serializer will generate JSON that looks like this:

        ```js
        {
          "TITLE": "Rails is omakase",
          "BODY": "Yep. Omakase.",
          "COMMENT_IDS": [ 1, 2, 3 ]
        }
        ```

        ## Tweaking the Default JSON

        If you just want to do some small tweaks on the default JSON,
        you can call super first and make the tweaks on the returned
        JSON.

        ```js
        App.PostSerializer = DS.RESTSerializer.extend({
          serialize: function(snapshot, options) {
            var json = this._super(snapshot, options);

            json.subject = json.title;
            delete json.title;

            return json;
          }
        });
        ```

        @method serialize
        @param {DS.Snapshot} snapshot
        @param {Object} options
        @return {Object} json
      */
      serialize: function(snapshot, options) {
        return this._super.apply(this, arguments);
      },

      /**
        You can use this method to customize the root keys serialized into the JSON.
        By default the REST Serializer sends the typeKey of a model, which is a camelized
        version of the name.

        For example, your server may expect underscored root objects.

        ```js
        App.ApplicationSerializer = DS.RESTSerializer.extend({
          serializeIntoHash: function(data, type, record, options) {
            var root = Ember.String.decamelize(type.typeKey);
            data[root] = this.serialize(record, options);
          }
        });
        ```

        @method serializeIntoHash
        @param {Object} hash
        @param {subclass of DS.Model} type
        @param {DS.Snapshot} snapshot
        @param {Object} options
      */
      serializeIntoHash: function(hash, type, snapshot, options) {
        hash[type.typeKey] = this.serialize(snapshot, options);
      },

      /**
        You can use this method to customize how polymorphic objects are serialized.
        By default the JSON Serializer creates the key by appending `Type` to
        the attribute and value from the model's camelcased model name.

        @method serializePolymorphicType
        @param {DS.Snapshot} snapshot
        @param {Object} json
        @param {Object} relationship
      */
      serializePolymorphicType: function(snapshot, json, relationship) {
        var key = relationship.key;
        var belongsTo = snapshot.belongsTo(key);
        key = this.keyForAttribute ? this.keyForAttribute(key) : key;
        if (Ember.isNone(belongsTo)) {
          json[key + "Type"] = null;
        } else {
          json[key + "Type"] = Ember.String.camelize(belongsTo.typeKey);
        }
      }
    });

    
    var ember$data$lib$serializers$rest$serializer$$default = ember$data$lib$serializers$rest$serializer$$RESTSerializer;

    /**
      The ActiveModelSerializer is a subclass of the RESTSerializer designed to integrate
      with a JSON API that uses an underscored naming convention instead of camelCasing.
      It has been designed to work out of the box with the
      [active\_model\_serializers](https://github.com/rails-api/active_model_serializers)
      Ruby gem. This Serializer expects specific settings using ActiveModel::Serializers,
      `embed :ids, embed_in_root: true` which sideloads the records.

      This serializer extends the DS.RESTSerializer by making consistent
      use of the camelization, decamelization and pluralization methods to
      normalize the serialized JSON into a format that is compatible with
      a conventional Rails backend and Ember Data.

      ## JSON Structure

      The ActiveModelSerializer expects the JSON returned from your server
      to follow the REST adapter conventions substituting underscored keys
      for camelcased ones.

      ### Conventional Names

      Attribute names in your JSON payload should be the underscored versions of
      the attributes in your Ember.js models.

      For example, if you have a `Person` model:

      ```js
      App.FamousPerson = DS.Model.extend({
        firstName: DS.attr('string'),
        lastName: DS.attr('string'),
        occupation: DS.attr('string')
      });
      ```

      The JSON returned should look like this:

      ```js
      {
        "famous_person": {
          "id": 1,
          "first_name": "Barack",
          "last_name": "Obama",
          "occupation": "President"
        }
      }
      ```

      Let's imagine that `Occupation` is just another model:

      ```js
      App.Person = DS.Model.extend({
        firstName: DS.attr('string'),
        lastName: DS.attr('string'),
        occupation: DS.belongsTo('occupation')
      });

      App.Occupation = DS.Model.extend({
        name: DS.attr('string'),
        salary: DS.attr('number'),
        people: DS.hasMany('person')
      });
      ```

      The JSON needed to avoid extra server calls, should look like this:

      ```js
      {
        "people": [{
          "id": 1,
          "first_name": "Barack",
          "last_name": "Obama",
          "occupation_id": 1
        }],

        "occupations": [{
          "id": 1,
          "name": "President",
          "salary": 100000,
          "person_ids": [1]
        }]
      }
      ```

    /**
      ### State

      Each record has a `currentState` property that explicitly tracks what
      state a record is in at any given time. For instance, if a record is
      newly created and has not yet been sent to the adapter to be saved,
      it would be in the `root.loaded.created.uncommitted` state.  If a
      record has had local modifications made to it that are in the
      process of being saved, the record would be in the
      `root.loaded.updated.inFlight` state. (This state paths will be
      explained in more detail below.)

      Events are sent by the record or its store to the record's
      `currentState` property. How the state reacts to these events is
      dependent on which state it is in. In some states, certain events
      will be invalid and will cause an exception to be raised.

      States are hierarchical and every state is a substate of the
      `RootState`. For example, a record can be in the
      `root.deleted.uncommitted` state, then transition into the
      `root.deleted.inFlight` state. If a child state does not implement
      an event handler, the state manager will attempt to invoke the event
      on all parent states until the root state is reached. The state
      hierarchy of a record is described in terms of a path string. You
      can determine a record's current state by getting the state's
      `stateName` property:

      ```javascript
      record.get('currentState.stateName');
      //=> "root.created.uncommitted"
       ```

      The hierarchy of valid states that ship with ember data looks like
      this:

      ```text
      * root
        * deleted
          * saved
          * uncommitted
          * inFlight
        * empty
        * loaded
          * created
            * uncommitted
            * inFlight
          * saved
          * updated
            * uncommitted
            * inFlight
        * loading
      ```

      The `DS.Model` states are themselves stateless. What that means is
      that, the hierarchical states that each of *those* points to is a
      shared data structure. For performance reasons, instead of each
      record getting its own copy of the hierarchy of states, each record
      points to this global, immutable shared instance. How does a state
      know which record it should be acting on? We pass the record
      instance into the state's event handlers as the first argument.

      The record passed as the first parameter is where you should stash
      state about the record if needed; you should never store data on the state
      object itself.

      ### Events and Flags

      A state may implement zero or more events and flags.

      #### Events

      Events are named functions that are invoked when sent to a record. The
      record will first look for a method with the given name on the
      current state. If no method is found, it will search the current
      state's parent, and then its grandparent, and so on until reaching
      the top of the hierarchy. If the root is reached without an event
      handler being found, an exception will be raised. This can be very
      helpful when debugging new features.

      Here's an example implementation of a state with a `myEvent` event handler:

      ```javascript
      aState: DS.State.create({
        myEvent: function(manager, param) {
          console.log("Received myEvent with", param);
        }
      })
      ```

      To trigger this event:

      ```javascript
      record.send('myEvent', 'foo');
      //=> "Received myEvent with foo"
      ```

      Note that an optional parameter can be sent to a record's `send()` method,
      which will be passed as the second parameter to the event handler.

      Events should transition to a different state if appropriate. This can be
      done by calling the record's `transitionTo()` method with a path to the
      desired state. The state manager will attempt to resolve the state path
      relative to the current state. If no state is found at that path, it will
      attempt to resolve it relative to the current state's parent, and then its
      parent, and so on until the root is reached. For example, imagine a hierarchy
      like this:

          * created
            * uncommitted <-- currentState
            * inFlight
          * updated
            * inFlight

      If we are currently in the `uncommitted` state, calling
      `transitionTo('inFlight')` would transition to the `created.inFlight` state,
      while calling `transitionTo('updated.inFlight')` would transition to
      the `updated.inFlight` state.

      Remember that *only events* should ever cause a state transition. You should
      never call `transitionTo()` from outside a state's event handler. If you are
      tempted to do so, create a new event and send that to the state manager.

      #### Flags

      Flags are Boolean values that can be used to introspect a record's current
      state in a more user-friendly way than examining its state path. For example,
      instead of doing this:

      ```javascript
      var statePath = record.get('stateManager.currentPath');
      if (statePath === 'created.inFlight') {
        doSomething();
      }
      ```

      You can say:

      ```javascript
      if (record.get('isNew') && record.get('isSaving')) {
        doSomething();
      }
      ```

      If your state does not set a value for a given flag, the value will
      be inherited from its parent (or the first place in the state hierarchy
      where it is defined).

      The current set of flags are defined below. If you want to add a new flag,
      in addition to the area below, you will also need to declare it in the
      `DS.Model` class.

    // Implementation notes:
    //
    // Each state has a boolean value for all of the following flags:
    //
    // * isLoaded: The record has a populated `data` property. When a
    //   record is loaded via `store.find`, `isLoaded` is false
    //   until the adapter sets it. When a record is created locally,
    //   its `isLoaded` property is always true.
    // * isDirty: The record has local changes that have not yet been
    //   saved by the adapter. This includes records that have been
    //   created (but not yet saved) or deleted.
    // * isSaving: The record has been committed, but
    //   the adapter has not yet acknowledged that the changes have
    //   been persisted to the backend.
    // * isDeleted: The record was marked for deletion. When `isDeleted`
    //   is true and `isDirty` is true, the record is deleted locally
    //   but the deletion was not yet persisted. When `isSaving` is
    //   true, the change is in-flight. When both `isDirty` and
    //   `isSaving` are false, the change has persisted.
    // * isError: The adapter reported that it was unable to save
    //   local changes to the backend. This may also result in the
    //   record having its `isValid` property become false if the
    //   adapter reported that server-side validations failed.
    // * isNew: The record was created on the client and the adapter
    //   did not yet report that it was successfully saved.
    // * isValid: The adapter did not report any server-side validation
    //   failures.

    //     before being used internally.
    //   * +clientId+ means a transient numerical identifier generated at runtime by
    //     the data store. It is important primarily because newly created objects may
    //     not yet have an externally generated id.
    //   * +reference+ means a record reference object, which holds metadata about a
    //     record, even if it has not yet been fully materialized.
    //   * +type+ means a subclass of DS.Model.

    // Used by the store to normalize IDs entering the store.  Despite the fact
    // that developers may provide IDs as numbers (e.g., `store.find(Person, 1)`),
    // it is important that internally we use strings, since IDs may be serialized
    // and lose type information.  For example, Ember's router may put a record's
    // ID into the URL, and if we later try to deserialize that URL and find the
    // corresponding record, we will not know if it is a string or a number.

    /**
      The store contains all of the data for records loaded from the server.
      It is also responsible for creating instances of `DS.Model` that wrap
      the individual data for a record, so that they can be bound to in your
      Handlebars templates.

      Define your application's store like this:

      ```javascript
      MyApp.ApplicationStore = DS.Store.extend();
      ```

      Most Ember.js applications will only have a single `DS.Store` that is
      automatically created by their `Ember.Application`.

      You can retrieve models from the store in several ways. To retrieve a record
      for a specific id, use `DS.Store`'s `find()` method:

      ```javascript
      store.find('person', 123).then(function (person) {
      });
      ```

      By default, the store will talk to your backend using a standard
      REST mechanism. You can customize how the store talks to your
      backend by specifying a custom adapter:

      ```javascript
      MyApp.ApplicationAdapter = MyApp.CustomAdapter
      ```

      You can learn more about writing a custom adapter by reading the `DS.Adapter`
      documentation.

      ### Store createRecord() vs. push() vs. pushPayload()

      The store provides multiple ways to create new record objects. They have
      some subtle differences in their use which are detailed below:

      [createRecord](#method_createRecord) is used for creating new
      records on the client side. This will return a new record in the
      `created.uncommitted` state. In order to persist this record to the
      backend you will need to call `record.save()`.

      [push](#method_push) is used to notify Ember Data's store of new or
      updated records that exist in the backend. This will return a record
      in the `loaded.saved` state. The primary use-case for `store#push` is
      to notify Ember Data about record updates (full or partial) that happen
      outside of the normal adapter methods (for example
      [SSE](http://dev.w3.org/html5/eventsource/) or [Web
      Sockets](http://www.w3.org/TR/2009/WD-websockets-20091222/)).

      [pushPayload](#method_pushPayload) is a convenience wrapper for
      `store#push` that will deserialize payloads if the
      Serializer implements a `pushPayload` method.

      Note: When creating a new record using any of the above methods
      Ember Data will update `DS.RecordArray`s such as those returned by
      `store#all()`, `store#findAll()` or `store#filter()`. This means any
      data bindings or computed properties that depend on the RecordArray
      will automatically be synced to include the new or updated record
      values.

      /**
        This is the main entry point into finding records. The first parameter to
        this method is the model's name as a string.

        ---

        To find a record by ID, pass the `id` as the second parameter:

        ```javascript
        store.find('person', 1);
        ```

        The `find` method will always return a **promise** that will be resolved
        with the record. If the record was already in the store, the promise will
        be resolved immediately. Otherwise, the store will ask the adapter's `find`
        method to find the necessary data.

        The `find` method will always resolve its promise with the same object for
        a given type and `id`.

        ---

        You can optionally `preload` specific attributes and relationships that you know of
        by passing them as the third argument to find.

        For example, if your Ember route looks like `/posts/1/comments/2` and your API route
        for the comment also looks like `/posts/1/comments/2` if you want to fetch the comment
        without fetching the post you can pass in the post to the `find` call:

        ```javascript
        store.find('comment', 2, {post: 1});
        ```

        If you have access to the post model you can also pass the model itself:

        ```javascript
        store.find('post', 1).then(function (myPostModel) {
          store.find('comment', 2, {post: myPostModel});
        });
        ```

        This way, your adapter's `find` or `buildURL` method will be able to look up the
        relationship on the record and construct the nested URL without having to first
        fetch the post.

        ---

        To find all records for a type, call `find` with no additional parameters:

        ```javascript
        store.find('person');
        ```

        This will ask the adapter's `findAll` method to find the records for the
        given type, and return a promise that will be resolved once the server
        returns the values. The promise will resolve into all records of this type
        present in the store, even if the server only returns a subset of them.

        ---

        To find a record by a query, call `find` with a hash as the second
        parameter:

        ```javascript
        store.find('person', { page: 1 });
        ```

        By passing an object `{page: 1}` as an argument to the find method, it
        delegates to the adapter's findQuery method. The adapter then makes
        a call to the server, transforming the object `{page: 1}` as parameters
        that are sent along, and will return a RecordArray when the promise
        resolves.

        Exposing queries this way seems preferable to creating an abstract query
        language for all server-side queries, and then require all adapters to
        implement them.

        The call made to the server, using a Rails backend, will look something like this:

        ```
        Started GET "/api/v1/person?page=1"
        Processing by Api::V1::PersonsController#index as HTML
        Parameters: {"page"=>"1"}
        ```

        If you do something like this:

        ```javascript
        store.find('person', {ids: [1, 2, 3]});
        ```

        The call to the server, using a Rails backend, will look something like this:

        ```
        Started GET "/api/v1/person?ids%5B%5D=1&ids%5B%5D=2&ids%5B%5D=3"
        Processing by Api::V1::PersonsController#index as HTML
        Parameters: {"ids"=>["1", "2", "3"]}
        ```

      /**
        Takes a type and filter function, and returns a live RecordArray that
        remains up to date as new records are loaded into the store or created
        locally.

        The filter function takes a materialized record, and returns true
        if the record should be included in the filter and false if it should
        not.

        Example

        ```javascript
        store.filter('post', function(post) {
          return post.get('unread');
        });
        ```

        The filter function is called once on all records for the type when
        it is created, and then once on each newly loaded or created record.

        If any of a record's properties change, or if it changes state, the
        filter function will be invoked again to determine whether it should
        still be in the array.

        Optionally you can pass a query, which is the equivalent of calling
        [find](#method_find) with that same query, to fetch additional records
        from the server. The results returned by the server could then appear
        in the filter if they match the filter function.

        The query itself is not used to filter records, it's only sent to your
        server for you to be able to do server-side filtering. The filter
        function will be applied on the returned results regardless.

        Example

        ```javascript
        store.filter('post', { unread: true }, function(post) {
          return post.get('unread');
        }).then(function(unreadPosts) {
          unreadPosts.get('length'); // 5
          var unreadPost = unreadPosts.objectAt(0);

        This method expects normalized data:

        * The ID is a key named `id` (an ID is mandatory)
        * The names of attributes are the ones you used in
          your model's `DS.attr`s.
        * Your relationships must be:
          * represented as IDs or Arrays of IDs
          * represented as model instances
          * represented as URLs, under the `links` key

        For this model:

        ```js
        App.Person = DS.Model.extend({
          firstName: DS.attr(),
          lastName: DS.attr(),

          children: DS.hasMany('person')
        });
        ```

        To represent the children as IDs:

        ```js
        {
          id: 1,
          firstName: "Tom",
          lastName: "Dale",
          children: [1, 2, 3]
        }
        ```

        To represent the children relationship as a URL:

        ```js
        {
          id: 1,
          firstName: "Tom",
          lastName: "Dale",
          links: {
            children: "/people/1/children"
          }
        }

        If you're streaming data or implementing an adapter, make sure
        that you have converted the incoming data into this form. The
        store's [normalize](#method_normalize) method is a convenience
        helper for converting a json payload into the form Ember Data
        expects.

        ```js
        store.push('person', store.normalize('person', data));
        ```

        records, as well as to update existing records.

        @method push

        This method can be used both to push in brand new

        can push in more than one type of object at once.
        All objects should be in the format expected by the
        serializer.

        var pushData = {
          posts: [

          comments: [
            {id: 2, comment_body: "Insightful comment"}
          ]
        }

        store.pushPayload(pushData);
        ```

        By default, the data will be deserialized using a default
        serializer (the application serializer if it exists).

        Alternatively, `pushPayload` will accept a model type which
        will determine which serializer will process the payload.
        However, the serializer itself (processing this data via
        `normalizePayload`) will not know which model it is
        deserializing.

        ```js
        App.ApplicationSerializer = DS.ActiveModelSerializer;
        App.PostSerializer = DS.JSONSerializer;
        store.pushPayload('comment', pushData); // Will use the ApplicationSerializer

      This code initializes Ember-Data onto an Ember application.

      If an Ember.js developer defines a subclass of DS.Store on their application,
      as `App.ApplicationStore` (or via a module system that resolves to `store:application`)
      this code will automatically instantiate it and make it available on the
      router.

      Additionally, after an application's controllers have been injected, they will
      each have the store made available to them.

      For example, imagine an Ember.js application with the following classes:

      App.ApplicationStore = DS.Store.extend({
        adapter: 'custom'
      });

      App.PostsController = Ember.ArrayController.extend({
        // ...
      });

      When the application is initialized, `App.ApplicationStore` will automatically be
      instantiated, and the instance of `App.PostsController` will have its `store`
      property set to that instance.

      Note that this code will only be run if the `ember-application` package is
      loaded. If Ember Data is being used in an environment other than a
      typical application (e.g., node.js where only `ember-runtime` is available),
      this code will be ignored.

    /**
      ## Using Embedded Records

      `DS.EmbeddedRecordsMixin` supports serializing embedded records.

      To set up embedded records, include the mixin when extending a serializer
      then define and configure embedded (model) relationships.

      Below is an example of a per-type serializer ('post' type).

      ```js
      App.PostSerializer = DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
        attrs: {
          author: { embedded: 'always' },
          comments: { serialize: 'ids' }
        }
      });
      ```
      Note that this use of `{ embedded: 'always' }` is unrelated to
      the `{ embedded: 'always' }` that is defined as an option on `DS.attr` as part of
      defining a model while working with the ActiveModelSerializer.  Nevertheless,
      using `{ embedded: 'always' }` as an option to DS.attr is not a valid way to setup
      embedded records.

      The `attrs` option for a resource `{ embedded: 'always' }` is shorthand for:

      ```js
      {
        serialize: 'records',
        deserialize: 'records'
      }
      ```

      ### Configuring Attrs

      A resource's `attrs` option may be set to use `ids`, `records` or false for the
      `serialize`  and `deserialize` settings.

      The `attrs` property can be set on the ApplicationSerializer or a per-type
      serializer.

      In the case where embedded JSON is expected while extracting a payload (reading)
      the setting is `deserialize: 'records'`, there is no need to use `ids` when
      extracting as that is the default behavior without this mixin if you are using
      the vanilla EmbeddedRecordsMixin. Likewise, to embed JSON in the payload while
      serializing `serialize: 'records'` is the setting to use. There is an option of
      not embedding JSON in the serialized payload by using `serialize: 'ids'`. If you
      do not want the relationship sent at all, you can use `serialize: false`.


      ### EmbeddedRecordsMixin defaults
      If you do not overwrite `attrs` for a specific relationship, the `EmbeddedRecordsMixin`
      will behave in the following way:

      BelongsTo: `{ serialize: 'id', deserialize: 'id' }`
      HasMany:   `{ serialize: false, deserialize: 'ids' }`

      ### Model Relationships

      Embedded records must have a model defined to be extracted and serialized. Note that
      when defining any relationships on your model such as `belongsTo` and `hasMany`, you
      should not both specify `async:true` and also indicate through the serializer's
      `attrs` attribute that the related model should be embedded.  If a model is
      declared embedded, then do not use `async:true`.

      To successfully extract and serialize embedded records the model relationships
      must be setup correcty See the
      [defining relationships](/guides/models/defining-models/#toc_defining-relationships)
      section of the **Defining Models** guide page.

      Records without an `id` property are not considered embedded records, model
      instances must have an `id` property to be used with Ember Data.

      ### Example JSON payloads, Models and Serializers

      **When customizing a serializer it is important to grok what the customizations
      are. Please read the docs for the methods this mixin provides, in case you need
      to modify it to fit your specific needs.**

      For example review the docs for each method of this mixin:
      * [normalize](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_normalize)
      * [serializeBelongsTo](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_serializeBelongsTo)
      * [serializeHasMany](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_serializeHasMany)

        Serialize `belongsTo` relationship when it is configured as an embedded object.

        This example of an author model belongs to a post model:

        ```js
        Post = DS.Model.extend({
          title:    DS.attr('string'),
          body:     DS.attr('string'),
          author:   DS.belongsTo('author')
        });

        Author = DS.Model.extend({
          name:     DS.attr('string'),
          post:     DS.belongsTo('post')
        });
        ```

        Use a custom (type) serializer for the post model to configure embedded author

        ```js
        App.PostSerializer = DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
          attrs: {
            author: {embedded: 'always'}
          }
        })
        ```

        A payload with an attribute configured for embedded records can serialize
        the records together under the root attribute's payload:

        ```js
        {
          "post": {
            "id": "1"

        @method serializeBelongsTo
        @param {DS.Snapshot} snapshot

          return;
        }
        var includeIds = this.hasSerializeIdsOption(attr);
        var includeRecords = this.hasSerializeRecordsOption(attr);
        var embeddedSnapshot = snapshot.belongsTo(attr);
        var key;
        if (includeIds) {
          key = this.keyForRelationship(attr, relationship.kind);
          if (!embeddedSnapshot) {
            json[key] = null;
          } else {
            json[key] = embeddedSnapshot.id;
          }
        } else if (includeRecords) {
          key = this.keyForAttribute(attr);
          if (!embeddedSnapshot) {
            json[key] = null;
          } else {
            json[key] = embeddedSnapshot.record.serialize({ includeId: true });
            this.removeEmbeddedForeignKey(snapshot, embeddedSnapshot, relationship, json[key]);
          }
        }
      },

      /**
        Serialize `hasMany` relationship when it is configured as embedded objects.

        This example of a post model has many comments:

        ```js
        Post = DS.Model.extend({
          title:    DS.attr('string'),
          body:     DS.attr('string'),
          comments: DS.hasMany('comment')
        });

        Comment = DS.Model.extend({
          body:     DS.attr('string'),
          post:     DS.belongsTo('post')
        });
        ```

        Use a custom (type) serializer for the post model to configure embedded comments

        ```js
        App.PostSerializer = DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
          attrs: {
            comments: {embedded: 'always'}
          }
        })
        ```

        A payload with an attribute configured for embedded records can serialize
        the records together under the root attribute's payload:

        ```js
        {
          "post": {
            "id": "1"
            "title": "Rails is omakase",
            "body": "I want this for my ORM, I want that for my template language..."
            "comments": [{
              "id": "1",
              "body": "Rails is unagi"
            }, {
              "id": "2",
              "body": "Omakase O_o"
            }]
          }
        }
        ```

        The attrs options object can use more specific instruction for extracting and
        serializing. When serializing, an option to embed `ids` or `records` can be set.
        When extracting the only option is `records`.

        So `{embedded: 'always'}` is shorthand for:
        `{serialize: 'records', deserialize: 'records'}`

        To embed the `ids` for a related object (using a hasMany relationship):

        ```js
        App.PostSerializer = DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
          attrs: {
            comments: {serialize: 'ids', deserialize: 'records'}
          }
        })
        ```

        ```js
        {
          "post": {
            "id": "1"
            "title": "Rails is omakase",
            "body": "I want this for my ORM, I want that for my template language..."
            "comments": ["1", "2"]
          }
        }
        ```

    /**
      `DS.belongsTo` is used to define One-To-One and One-To-Many
      relationships on a [DS.Model](/api/data/classes/DS.Model.html).


      `DS.belongsTo` takes an optional hash as a second parameter, currently
      supported options are:

      - `async`: A boolean value used to explicitly declare this to be an async relationship.
      - `inverse`: A string used to identify the inverse property on a
        related model in a One-To-Many relationship. See [Explicit Inverses](#toc_explicit-inverses)

      #### One-To-One
      To declare a one-to-one relationship between two models, use
      `DS.belongsTo`:

      ```javascript
      App.User = DS.Model.extend({
        profile: DS.belongsTo('profile')
      });

      App.Profile = DS.Model.extend({
        user: DS.belongsTo('user')
      });
      ```

      #### One-To-Many
      To declare a one-to-many relationship between two models, use
      `DS.belongsTo` in combination with `DS.hasMany`, like this:

      ```javascript
      App.Post = DS.Model.extend({
        comments: DS.hasMany('comment')
      });

      App.Comment = DS.Model.extend({
        post: DS.belongsTo('post')
      });
      ```

      You can avoid passing a string as the first parameter. In that case Ember Data
      will infer the type from the key name.

      ```javascript
      App.Comment = DS.Model.extend({
        post: DS.belongsTo()
      });
      ```

      will lookup for a Post type.

    /**
      `DS.hasMany` is used to define One-To-Many and Many-To-Many
      relationships on a [DS.Model](/api/data/classes/DS.Model.html).

      `DS.hasMany` takes an optional hash as a second parameter, currently
      supported options are:

      - `async`: A boolean value used to explicitly declare this to be an async relationship.
      - `inverse`: A string used to identify the inverse property on a related model.

      #### One-To-Many
      To declare a one-to-many relationship between two models, use
      `DS.belongsTo` in combination with `DS.hasMany`, like this:

      ```javascript
      App.Post = DS.Model.extend({
        comments: DS.hasMany('comment')
      });

      App.Comment = DS.Model.extend({
        post: DS.belongsTo('post')
      });
      ```

      #### Many-To-Many
      To declare a many-to-many relationship between two models, use
      `DS.hasMany`:

      ```javascript
      App.Post = DS.Model.extend({
        tags: DS.hasMany('tag')
      });

      App.Tag = DS.Model.extend({
        posts: DS.hasMany('post')
      });
      ```

      You can avoid passing a string as the first parameter. In that case Ember Data
      will infer the type from the singularized key name.

      ```javascript
      App.Post = DS.Model.extend({
        tags: DS.hasMany()
      });
      ```

      will lookup for a Tag type.

      #### Explicit Inverses

      Ember Data will do its best to discover which relationships map to
      one another. In the one-to-many code above, for example, Ember Data
      can figure out that changing the `comments` relationship should update
      the `post` relationship on the inverse because post is the only
      relationship to that model.

      However, sometimes you may have multiple `belongsTo`/`hasManys` for the
      same type. You can specify which property on the related model is
      the inverse using `DS.hasMany`'s `inverse` option:

      ```javascript
      var belongsTo = DS.belongsTo,
          hasMany = DS.hasMany;

      App.Comment = DS.Model.extend({
        onePost: belongsTo('post'),
        twoPost: belongsTo('post'),
        redPost: belongsTo('post'),
        bluePost: belongsTo('post')
      });

      App.Post = DS.Model.extend({
        comments: hasMany('comment', {
          inverse: 'redPost'
        })
      });
      ```

      You can also specify an inverse on a `belongsTo`, which works how
      you'd expect.

        Given a callback, iterates over each of the relationships in the model,

        descriptor.


        The callback method you provide should have the following signature (all
        parameters are optional):

        ```javascript
        function(name, descriptor);
        ```

        - `name` the name of the current property in the iteration
        - `descriptor` the meta object that describes this relationship

        The relationship descriptor argument is an object with the following properties.

       - **key** <span class="type">String</span> the name of this relationship on the Model
       - **kind** <span class="type">String</span> "hasMany" or "belongsTo"
       - **options** <span class="type">Object</span> the original options hash passed when the relationship was declared
       - **parentType** <span class="type">DS.Model</span> the type of the Model that owns this relationship
       - **type** <span class="type">DS.Model</span> the type of the related Model

        Note that in addition to a callback, you can also pass an optional target
        object that will be set as `this` on the context.

        Example

        ```javascript
        App.ApplicationSerializer = DS.JSONSerializer.extend({
          serialize: function(record, options) {
            var json = {};

            record.eachRelationship(function(name, descriptor) {
              if (descriptor.kind === 'hasMany') {
                var serializedHasManyName = name.toUpperCase() + '_IDS';
                json[name.toUpperCase()] = record.get(name).mapBy('id');
              }
            });

            return json;
          }
        });
        ```

        @method eachRelationship

        @param {any} binding the value to which the callback's `this` should be bound
