I am developing simple CRUD application in Ember.js and Ruby on Rails

Versions:

DEBUG: Ember      : 1.6.0-beta.3 ember.js?body=1:3917
DEBUG: Ember Data : 1.0.0-beta.7+canary.f482da04 ember.js?body=1:3917
DEBUG: Handlebars : 1.3.0 ember.js?body=1:3917
DEBUG: jQuery     : 1.11.0

Ruby on Rails 4.0.3

I am using Railscasts tutorial pretty good, but some things have changed a lot (e.g. ember-data).

When I save record, it throws 2 exceptions:

Error: No model was found for 'id'

Code:

-router.js

EmTasks.Router.map(function(){
  return this.route("lists", {
    path: '/'
  });
});

EmTasks.ListsRoute = Ember.Route.extend({
  model: function() {
    return this.store.find('list');
  }
});

-controller/lists_controller.js

EmTasks.ListsController = Em.ArrayController.extend({
  addList: function() {
    this.store.createRecord('list', {
      name: this.get('newListName')
    }).save();
    return this.set('newListName', '');
  }
});

-models/list.js

EmTasks.List = DS.Model.extend({
  name: DS.attr('string')
});

-templates/lists.handlebars

<div id="container">
  <h1>em-tasks</h1>
  {{view Ember.TextField valueBinding="newListName" action="addList"}}
  {{newListName}}

  {{#each controller}}
    <p>{{name}}</p>
  {{/each}}
</div>

I have found a solution.

Just set self.include_root_in_json to true in Rails.

-config/initializers/wrap_parameters.rb

ActiveSupport.on_load(:active_record) do
 self.include_root_in_json = true
end

then we get in JSON response

{
  list: {
    id: 1,
    name: "icebox"
  }
}

instead of

{
  id: 1,
  name: "icebox"
}
