  // /src/Acme/DemoBundle/Controller/MediaCRUDController.php
  namespace AppBundle\Controller;
  
  use Sonata\AdminBundle\Controller\CRUDController;
  
  class RatingController extends CRUDController
  {
      public function indexAction()
      {
          eturn $this-&gt;render('CCApplicationBundle:Default:rating.html.twig');
      }
  }
  </code></pre>
  
  <p>and my route:</p>
  
  <pre><code>admin_dashboard_rating:
    path:  /rating
    defaults: { _controller: AppBundle:Rating:index }
