Idiomatic way to filter on nested route?

[neverfox]

I'm trying to figure out how to do filtering on child routes with emberfire since the adapter doesn't implement findQuery. I have the following:

  Advisor = DS.Model.extend
    accounts: hasMany "account", async: true

 Account = DS.Model.extend
    advisor: belongsTo "advisor", async: true

  App.Router.map ->
    @resource "advisor",
      path: "/advisor/:advisor_id", ->
        @resource "advisor.accounts",
          path: "/accounts", ->
            @route "new"

 AdvisorAccountsRoute = Ember.Route.extend #/advisor/:advisor_id/accounts
    model: ->
      # TODO: fetch only this advisor's accounts
      @store.findAll "account"

As you can see it currently fetches all the accounts, but what I want is only the accounts for the advisor in question. Am I supposed to pull all of the accounts into my controller and then filter there (setting the controller to also have the model for the advisor so that I can perform the filter)? That seems less than ideal, but I cannot see any other way. What I would be tempted to do in any other case would be:

 AdvisorAccountsRoute = Ember.Route.extend #/advisor/:advisor_id/accounts
    model: ->
      @store.filter "account", (account) ->
        account.get("advisor").then (advisor) =>
          Ember.isEqual advisor, @modelFor "advisor"

This seems like a common enough scenario that I'm hoping someone will be able to provide an example of the most efficient way to do this. Note that it's imperative that the solution guarantee async resolution of all the data from Firebase before the controller starts computing anything.

What about something like this for your advisor accounts route?

model: function() {
  this.modelFor("advisor").get("accounts").then(function(accounts) {
    return accounts
  }
}

@JFickel Ah! I'm coming from using fireplace, where I had tried that and it didn't work (because it doesn't return a PromiseModel) and so I forgot to try it with emberFire. I'll comfirm and close this it if it works.

[neverfox]

I am curious though, for other reasons, is it something idiosyncratic about working with Firebase relationships that prevents or makes difficult implementing findQuery?

@neverfox I'm working on implementing findQuery() now and it's definitely an interesting paradigm to integrate with Ember

[neverfox]

@JFickel Yep, that works great.

@aputinski Would you mind pushing your branch for implementing findQuery()? I would like to check it out
