         $em = $this->container->get('doctrine')->getEntityManager();
            $categories = $em->getRepository('MyAppFilmothequeBundle:Categorie')->findAll();
                $format = $request->getRequestFormat();
                return $this->render('::index1.'.$format.'.twig', array('data' => array(
      'success' => true,
      'categories' => $categories,

Et quel est ton problème ?

[tabbabi]

il n'a rien afficher

[bilbot]

As tu des messages d'erreurs, des messages dans la log symfony ou autre ?

As tu essayé de déboguer avec xdebug ou avec des traces ?

Si non, passe au moins 30 minutes à le faire et indique nous les résultats de tes investigations...

[bilbot]

et donc ce template est il au bon endroit ? As tu lu la doc sur les templates sur le site de symfony ?

[tabbabi]

maintenant le navigateur affiche le contenu de la page index1.html.twig(c'est à dire le code) !

[bilbot]

que contient ce fichier ?

[Tilwan]

Je pense que ton problème viens de cette ligne :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

return $this->render('::index1.'.$format.'.twig', array('data' => array(
      'success' => true,
      'categories' => $categories,
 
    )));

Tu dis à ton controller de retourner la vue index1.html.twig et je pense que ce serai plus judicieux d'utiliser la classe Response car tu n'as pas besoin de template dans ce cas :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

return new Response(json_encode(array( 'success' => true, 'categories' => $categories)));

Tu n'a pas besoin de préciser le header-content sachant que tu l'as déjà fait dans la définition de la route.
