I'm doing an AdvertPlatform with Symfony 2.5 and PHP 5.3.
I want to add a feature that is : when a user see(by clicking on it) an advert, we can see a text "Seen by : {{username}}".
I started add a new Entity nammed AdvertReader with a relation OneToMany between Advert and AdvertReader:
Advert.php:
/**
* Advert
*
* @ORM\Table()
* @ORM\Entity(repositoryClass="Society\PerfclientBundle\Entity\AdvertRepository")
* @ORM\HasLifecycleCallbacks()
* @UniqueEntity(fields="title", message="Une annonce existe déjà avec ce titre.")
*/
class Advert
{
public function __construct()
{
$this->date = new \Datetime();
}
/**
*
* @ORM\OneToMany(targetEntity="Society\PerfclientBundle\Entity\AdvertReader", mappedBy="advert", cascade={"persist"})
*/
private $readers;
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var \DateTime
*
* @ORM\Column(name="date", type="datetime")
*/
private $date;
/**
* @var string
*
* @ORM\Column(name="title", type="string", length=255, unique=true)
*
* @Assert\Length(min=10, minMessage="Le titre de l'annonce doit faire au moins {{ limit }} caractères.")
*/
private $title;
/**
* @var string
*
* @ORM\Column(name="category", type="string", length=255)
*/
private $category;
/**
* @var string
*
* @ORM\Column(name="author", type="string", length=255)
*/
private $author;
/**
* @var string
*
* @ORM\Column(name="content", type="text")
* @Assert\Length(min=10, minMessage="Le contenu de l'annonce doit faire au moins {{ limit }} caractères.")
*/
private $content;
/**
* @ORM\Column(name="updated_at", type="datetime", nullable=true)
*/
private $updatedAt;`
AdvertReader.php :
/**
* AdvertReader
*
* @ORM\Table()
* @ORM\Entity
*/
class AdvertReader
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\ManyToOne(targetEntity="Society\PerfclientBundle\Entity\Advert", inversedBy="readers")
* @ORM\JoinColumn(name="advert_id", referencedColumnName="id")
*/
private $advert;
/**
* @var string
*
* @ORM\Column(name="username", type="string", length=255)
*/
private $username;
/**
* @var \DateTime
*
* @ORM\Column(name="created_at", type="datetime")
*/
private $createdAt;
/**
* @var \DateTime
*
* @ORM\Column(name="updated_at", type="datetime")
*/
private $updatedAt;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set advert
*
* @param integer $advert
* @return AdvertReader
*/
public function setAdvert($advert)
{
$this->advert = $advert;
return $this;
}
/**
* Get advert
*
* @return integer
*/
public function getAdvert()
{
return $this->advert;
}
/**
* Set username
*
* @param string $username
* @return AdvertReader
*/
public function setUsername($username)
{
$this->username = $username;
return $this;
}
/**
* Get username
*
* @return string
*/
public function getUsername()
{
return $this->username;
}
And my viewAction()
/**
* @param $id

public function viewAction($id)
{
// On récupère le repository
$repository = $this->getDoctrine()
->getManager()
->getRepository('SocietyPerfclientBundle:Advert')
;
$advert = $repository->find($id);
if (null === $advert) {
throw new NotFoundHttpException("L'annonce d'id ".$id." n'existe pas.");
}
$securityContext = $this->container->get('security.context');
$user = $securityContext->getToken()->getUser();
if ($securityContext->isGranted('IS_AUTHENTICATED_FULLY')) {
$em = $this->getDoctrine()->getManager();
$queryBuilder = $em->createQueryBuilder();
$query = $queryBuilder->select('count(ar.id)')

if ($advertReaderCount <= 0) {
// l'utilisateur lis pour la 1er fois
$advertReader = new AdvertReader;
$advertReader->setAdvert($advert->getId());
$advertReader->setUpdatedAt(new \DateTime);
$advertReader->setUsername($user->getUsername());
$advertReader->setCreatedAt(new \DateTime);
$em->persist($advertReader);
$em->flush();
}
}
return $this->render('SocietyPerfclientBundle:Default:view.html.twig', array(
'advert' => $advert,
));
}

Error500 ORM Exception : Found entity of type on association Society\PerfclientBundle\Entity\AdvertReader#advert, but expecting Society\PerfclientBundle\Entity\Advert

What's wrong with my entity relation ? Please help me :)
