Ember Data 2.0 JSONAPISerializer

gistfile1.js

import DS from 'ember-data';
import Ember from 'ember';

export default DS.JSONAPISerializer.extend({
  normalizeArrayResponse: function(store, primaryModelClass, payload, id, requestType) {
    var data = {},
    extracted = [],
    root = 'data',
    type = Ember.String.pluralize(primaryModelClass.modelName);

    payload[type].forEach(function(e) {
      e.attributes = [];
      // iterate through the object and push any attributes into the attributes array
      Ember.keys(e).forEach(function(key) {
        // but don't push id or attributes itself into the array
        if (key !== 'id' && key !== 'attributes') {
          e.attributes[key] = e[key];
          delete e[key];
        }
      });
      // set the type
      e.type = type;
      extracted.push(e);
    });

    data[root] = extracted;
    return this._super(store, primaryModelClass, data, id, requestType);
  }
});

Partially working...
