Symfony Doctrine return empty values - symfony

Question

I use Symfony doctrine to set and get data from my MySQL database. I can push new data without any problem but when I try to get them with a findAll for exemple, I get an array with the good length but nothing in.
Here's my controller:
namespace KGN\CoreBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Response;
use Doctrine\ORM\EntityManagerInterface;
use KGN\CoreBundle\Entity\Appointment;
use KGN\CoreBundle\Entity\Testy;
class AdminController extends Controller
{
public function indexAction()
{
return $this->render('KGNCoreBundle:Admin:index.html.twig');
}
public function aptAction()
{
$rep = $this->getDoctrine()
->getRepository('KGNCoreBundle:Testy');
$testy = $rep->findAll();
// return new Response('This is for show : '. count($testy) );
return new JsonResponse($testy);
}
public function createAction()
{
$em = $this->getDoctrine()->getManager();
$testy = new Testy();
$testy->setTitre('Magnifique');
$testy->setName('Helicoptere');
$em->persist($testy);
$em->flush();
return new Response('This is for create');
}
}
and what I get on my view page
[{},{}]
And it's true that there is 2 elements in my SQL table.
( I have create my entity with php bin/console doctrine:generate:entity without edition stuff in the "Testy" class or rep )
Entity/Testy
namespace KGN\CoreBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Testy
*
* #ORM\Table(name="testy")
* #ORM\Entity(repositoryClass="KGN\CoreBundle\Repository\TestyRepository")
*/
class Testy
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="titre", type="string", length=255)
*/
private $titre;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* Get id
*
* #return int
*/
public function getId()
{
return $this->id;
}
/**
* Set titre
*
* #param string $titre
*
* #return Testy
*/
public function setTitre($titre)
{
$this->titre = $titre;
return $this;
}
/**
* Get titre
*
* #return string
*/
public function getTitre()
{
return $this->titre;
}
/**
* Set name
*
* #param string $name
*
* #return Testy
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* #return string
*/
public function getName()
{
return $this->name;
}
}
associed rep
namespace KGN\CoreBundle\Repository;
/**
* TestyRepository
*
* This class was generated by the Doctrine ORM. Add your own custom
* repository methods below.
*/
class TestyRepository extends \Doctrine\ORM\EntityRepository
{
}

Answer 1

Hi The Function findAll Return the correct answer but its return as array of Objects
And JsonResponse can't desplay Object.
to fixe that you have to create a custom function in your repository that return An array exemple
public function getAll() {
$qb = $this->createQueryBuilder('u');
return $qb->getQuery()->getArrayResult();
}

Answer 2

$em = $this->getDoctrine()->getManager();
$records = $em->getRepository("KGNCoreBundle:Testy")->findAll();
Hope its help you
