Bonjour; 

j ai un pb 

voila j'essai de récupérer le contenu de ma table via le bundle datatableBundle 

mais après avoir écris mon code ma table est vide  

voici mon controlleur:

 public function affichageFormulaireAction(Request $request)

	{
	 $isAjax= $request->isXmlHttpRequest();
	
    $datatable = $this->get('sg_datatables.factory')->create(RessourcesDatatable::class); // We have to provide the appropriate class name here
	
	$datatable->buildDatatable();
	var_dump($datatable);
	if ($isAjax)
	{
		
		$responseService = $this->get('sg_datatables.response');
		$responseService->setDatatable($datatable);

		$datatableQueryBuilder = $responseService->getDatatableQueryBuilder();

		$datatableQueryBuilder->buildQuery();

		return $responseService->getResponse();
	}
    return $this->render('PSAApplicationBundle:Ressource:AfficheFormulaire.html.twig', array(
        'datatable' => $datatable));
	
	}
voici mon datatablebundleRessources

}

 

	pouvez vous me donner un coup de main, 

je pense que le pb viens de ''data' qui n'est pas défini dans le $this->ajax->set

mais comment définr 'data' pour envoyer les données de ma table 

lorsque j'affiche j obtiens cette image:

je suis un peu perdu
