How to load a hasMany relationship?

[andrewhavens]

I have a route that loads a primary model and displays one of its hasMany relationships. I want to use ember-infinity to paginate the hasMany relationship. Currently, my template simply calls {{#each model.children as |child|}}. What do I need to modify in order to make this work with ember-infinity?

Hi @andrewhavens !

Currently we can't do that out of the box - Ember Infinity has a hard dependency on there being an paginated endpoint for the model you're actually displaying.

There's various ways to get around this, but the path of least resistance is to add/modify an API endpoint for your child model, like so:

host.com/api/child_models?parent_model_id=231&per_page=5&page=1

That way you can use a param (or bound param, if it's dynamic) for parent_model_id and paginate that relationship.

Please reopen if this doesn't solve your issue!

I think part of my question was simply how to change from a single model route to a route that returns multiple. I ended up with something like this. Posting it here in case it helps anyone else in the future.

# in coffeescript:

  model: (params) ->
    Ember.RSVP.hash
      parent: @store.findRecord('parent', params.parent_id)
      children: @infinityModel('child', parent_id: params.parent_id, modelPath: 'controller.model.children', perPage: 20, startingPage: 1)

perfect!

Above solution is not working for me. API request is still going to:
host.com/api/children?per_page=5&page=1&parent_id=1
