Symfony2 persist a ManyToOne with attributes - php

Question

This error appears when I try to persist my entity :
Warning: spl_object_hash() expects parameter 1 to be object, integer
given in
C:\wamp\www\projet\vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php
line 1601
This is my entity Site :
/**
* Etablissement
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="Intranet\RhBundle\Entity\SiteRepository")
*/
class Site {
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id; /**
* #ORM\OneToMany(targetEntity="Intranet\RhBundle\Entity\SiteEtablissement",
mappedBy="site", cascade={"persist", "remove"}, orphanRemoval=true)
* */
private $siteEtablissements;
}
This is my entity Etablissement :
/**
* Etablissement
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="Intranet\RhBundle\Entity\EtablissementRepository")
*/
class Etablissement {
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
}
And the entity for the relation :
/**
* #ORM\Entity(repositoryClass="Intranet\RhBundle\Entity\SiteEtablissementRepository")
*/
class SiteEtablissement {
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\ManyToOne(targetEntity="Intranet\RhBundle\Entity\Site", inversedBy="siteEtablissements")
* #ORM\JoinColumn(name="site_id", referencedColumnName="id")
*/
private $site;
/**
* #ORM\ManyToOne(targetEntity="Intranet\RhBundle\Entity\Etablissement")
* #ORM\JoinColumn(name="etablissement_id", referencedColumnName="id", onDelete="CASCADE")
*/
private $etablissement;
}
So I don't understand why I have this error, my mapping seems to be ok. I don't have any entity error and I have no error before to persist $site in my controller.
This is my controller :
public function gererEtablissementAction(Request $request, Site $site) {
$form = $this->createForm(new GererSiteEtabType(), $site);
if ($request->getMethod() == 'POST') {
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
foreach ($site->getSiteEtablissements() as $sitEtab)
if (is_null($sitEtab->getAutor()))
$sitEtab->setAutor($this->getUser());
$em->persist($site);
$em->flush();
$this->get('session')->getFlashBag()->add('success', "Les établissement du site " . $site->getNom() . " ont été modifiés avec succès !");
return $this->redirect($this->generateUrl('intranet_rh_homepage_employes'));
} else
$this->get('session')->getFlashBag()->add('danger', "Erreur de formulaire !");
}
return $this->render('IntranetRhBundle:Site:gererEtablissement.html.twig', array('site' => $site, 'form' => $form->createView()));
}
When I print $site->getSiteEtablissements, there are Site and Etablissement on each side of each object...
This is the build form :
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('siteEtablissements', 'collection', array(
'type' => new SiteEtablissementType(),
'allow_add' => true,
'allow_delete' => true,
'by_reference' => false,
'required' => false
))
;
}
And the subform :
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('etablissement', 'entity', array(
'label' => 'Etablissement :',
'class' => 'IntranetRhBundle:Etablissement',
'property' => 'nom',
'query_builder' => function(EtablissementRepository $er) {
// récupère les établissements triés par ordre alpabétique croissant de nom
return $er->createQueryBuilder('e')
->orderBy('e.nom', 'ASC');
},
'attr' => array('class' => 'form-control')
))
;
}

I find the error : a bad initialsiation of Autor.
Autor was initialise at "0" and in the loop I test if is_null. So 0 is not null and when it persists, there is an error ebcause there is no user with id 0...
