Error while processing route, factory is undefined

Question

I'm trying to fetch data (following a tutorial) via RESTAdapter and I'm getting an error I don't understand.

"Error while processing route: players.index" "factory is undefined" "Store<.modelFor@http://localhost:4200/assets/vendor.js:74981:1

Anyone idea of what I'm missing? Do I need install an add-on?

routes/players/index.js

import Ember from 'ember';

export default Ember.Route.extend({
  model: function() {
    return this.store.find('player');
  }
});

I wasn't able to reproduce your exact error, but working with what you shared I was able to get it to work by making these changes. If there is something different with your code leave a comment and I will take a look.

serializers/application.js

Since you are using a custom primary key (neo_id instead of id) you can change that here, as well as indicate that the stats records are embedded in the players data:

export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
  attrs : {
    stats: { embedded: 'always' }
  },
  primaryKey : 'neo_id'
});
