通过ember.js路由中的属性过滤多个模型

Question

I have the following RSVP hash in my IndexRoute which finds all slider records ( I need to use a hash because I need to load 2 models on this page). I can call sliders or this.sliders in the index template to successfully pass all the slider objects to a view component.

However, I need to filter these records by the page attribute "index". When I add filterBy to the IndexRoute, no records are returned.

How can I filter these records and use the resulting array in the template?

IndexRoute

App.IndexRoute = Ember.Route.extend({
    model: function() {
        return Ember.RSVP.hash({ 
            sliders: this.store.findAll("slider"), # Adding .filterBy("page", "index") fails to load anything
            products: this.store.findAll("products")
        });
    }
});

index.html

<script type="text/x-handlebars" data-template-name="index">
   {{mainpage-slider sliders=sliders}}
</script>

add the filter to the controller

App.IndexRoute = Ember.Route.extend({
  model: function() {
    return Ember.RSVP.hash({ 
      sliders: this.store.find("slider"), # Adding .filterBy("page", "index") fails to load anything
      products: this.store.find("products")
   });
  }
});

App.IndexController = Em.ObjectController.extend({
  filteredSlider: function(){
    return this.get('sliders').filterBy('page', 'index');
  }.property('sliders.@each.page')
});
