Ember-data error: "Assertion Failed: You need to pass a model name to the store's modelFor method"

Question

I'm getting this error when trying to consume the json from the backend. I'm using Ember CLI version 2.5.0 and the RestAdapter.

Here's my routes/products/index.js looks like:

export default Ember.Route.extend({
  actions: {
   [...]
  },
  model: function() {
    return this.store.findAll('product');
  }
});

And here's what my json looks like:

{
   "products":[
      {
         "id":9,
         "name":"Product A",
         "price_cents":1500,
         "margin_cents":0,
         "commission":0,
         "expiration":null,
         "track_stock":false,
         "stock_amount":5,
         "brand":{
            "id":2,
            "name":"SuperPet"
         },
         "group":{
            "id":1,
            "name":"Group A"
         }
      },
      {
         "id":8,
         "name":"Product B",
         "price_cents":1500,
         "margin_cents":0,
         "commission":0,
         "expiration":null,
         "track_stock":false,
         "stock_amount":5,
         "brand":{
            "id":1,
            "name":"Whiskas"
         },
         "group":{
            "id":1,
            "name":"Group B"
         }
      }
   ],
   "meta":{
      "pagination":{
         "per_page":null,
         "total_pages":4,
         "total_objects":10
      }
   }
}

And by request, here's the model:

import DS from 'ember-data';

const { attr, belongsTo } = DS;

export default DS.Model.extend({
  name: attr('string'),
  priceCents: attr('number'),
  marginCents: attr('number'),
  comission: attr('number'),
  expiration: attr('date'),
  trackStock: attr('boolean'),
  stockAmount: attr('number'),

  brand: belongsTo('brand')

});

Can you post your adapter, serializer (if any) and stack trace from console, which line is error coming from? — Daniel Kmak

I was having the same issue. This worked for me:

//app/serializers/product.js
import DS from 'ember-data';
import Ember from 'ember';

export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin,{   
    attrs: {
       brand: { embedded: 'always' },
       group: { embedded: 'always'}
  }
});
