Delete all items and perform a new query

[joshuadeanhall]

I have a list with a search feature. When a user performs a search I need to remove all items from the list and perform a new query to populate the list.

So far the best I have got is an action on the route that looks like

this.set('controller.model', this.infinityModel("items", {
id: params.Uid,
perPage: 25,
startingPage: 1,
filter: 'test'
}))

This deletes the items and does a new query but the scrolling fails. (Also I would prefer to be able to do this on the controller). I couldn't find any documentation on how to reset the list and wasn't sure the best place to ask how to perform this.

Yeah I've had a couple questions about resetting the list. The way you're doing it is how I recommend doing it - but I'll have a play around with this in the coming week and maybe roll an official solution. Stay tuned!

@joshuadeanhall - are you using ember data 1.13x by chance?

RE: controllers: You can do this from the controller also - but we recommend doing it from the route as controllers are set to be deprecated in ember 2.0+

@hhff I am using ember 1.13.4.

When doing what I posted above I get the following error after hitting the action that refreshes the model and going hitting the end of the first page (After the reload when it tries to load the next page it fails).

The result of a server query (on @model:item:) is immutable.

My action looks like this

    actions: {
    doStuff: function() {
      var params = this.controllerParams;
      this.set('controller.model', this.infinityModel("item", {
        clientFilingUid: params.Uid,
        perPage: ENV.APP.pageSize,
        startingPage: 1,
        filter: 'test'
      }))
    }
}

And my model() looks like
model: function (params, transition) {

    this.controllerParams = params;

    var model =  this.infinityModel("item", {
        clientFilingUid: params.Uid,
        perPage: ENV.APP.pageSize,
        startingPage: 1
    });
  return model;
}

Didn't know about controllers in 2.0 thanks for the advice.

[hhff]

gotcha. thanks for the info! traveling at the moment and won't have a chance to look into this for a couple weeks. Believe its related to #42

[hhff]

FWIW, we don't support 1.13.x of ember or ember data yet, there's a PR up for that at the moment

Have you considered using a queryParam? They can rerun your model hook for you and flush out your results: http://www.foraker.com/blog/creating-a-better-search-experience-with-ember

closing this for now - as I believe this is resolved
