我在创建实体Annonce时遇到问题。在Annonce中，我有一个Categorie。
创建Annonce曾经有用，但是现在，它不再起作用了（我不知道为什么）。
当我提交创建表单时，所有类别都会被删除（我在教义分析器中看到它），然后它尝试保存名称，但是我在表单中选择的类别已不存在，因为它已被删除就在之前。
我不知道为什么要删除这些内容。 这是我的代码：
AnnonceController newAction：
/**
* Creates a new annonce entity.
*
* @Route("/nouvelle", name="ad_new")
* @Method({"GET", "POST"})
*/
public function newAction(Request $request)
{
$annonce = new Annonce();
if ($this->get('security.authorization_checker')->isGranted('IS_AUTHENTICATED_REMEMBERED')) {
$annonce->setUser($this->getUser());
}
$em = $this->getDoctrine()->getManager();
$repoCategorie = $em->getRepository('AnnoncesBundle:Categorie');
$rootCategories = $repoCategorie->findRootCategories();
foreach ($rootCategories as $rootCategory)
{
$rootCategory->setEnfants($repoCategorie->findByParent($rootCategory));
}
$form = $this->createForm('AnnoncesBundle\Form\AnnonceType', $annonce);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$annonce->setComplexId(uniqid('', true));
$annonce->setDateCreation(new \DateTime("now"));
$annonce->setDateModification(new \DateTime("now"));
$em->persist($annonce);
$em->flush();
// On traite les image
$this->gerePhotos($annonce);
$stat = $em->getRepository("AppBundle:Stats")->find(1);
$stat->setNbAnnonces($stat->getNbAnnonces() + 1);
$em->flush();
$urlHelper = $this->container->get('AppBundle\Services\UrlHelper');
return $this->redirectToRoute('ad_confirme', array('id' => $annonce->getId(), 'complexId' => $annonce->getComplexId()));
}
return $this->render('annonce/new.html.twig', array(
'annonce' => $annonce,
'form' => $form->createView(),
'categories' => $rootCategories
));
}
Categorie在Annonce实体中定义如下：
/**
* @ORM\ManyToOne(targetEntity="AnnoncesBundle\Entity\Categorie")
* @ORM\JoinColumn(name="categorie_code", referencedColumnName="code")
* @Assert\NotBlank(message="Merci de renseigner la catégorie")
*/
private $categorie;
Categorie实体代码：
<?php
namespace AnnoncesBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Categorie
*
* @ORM\Table(name="categorie")
* @ORM\Entity(repositoryClass="AnnoncesBundle\Repository\CategorieRepository")
*/
class Categorie
{
/**
* @var string
*
* @ORM\Column(name="nom", type="string", length=255)
*/
private $nom;
/**
* @var int
*
* @ORM\Column(name="position_affichage", type="integer")
*/
private $positionAffichage;
/**
* @var string
* @ORM\Id
* @ORM\Column(name="code", type="string", length=255)
*/
private $code;
/**
* Many Categories have One Category.
* @ORM\ManyToOne(targetEntity="AnnoncesBundle\Entity\Categorie", inversedBy="enfants")
* @ORM\JoinColumn(name="parent_code", referencedColumnName="code", nullable=true)
*/
private $parent;
/**
* One Category has Many children Categories.
* @ORM\OneToMany(targetEntity="AnnoncesBundle\Entity\Categorie", mappedBy="parent",orphanRemoval=true, cascade={"remove"})
*/
private $enfants;
public function __construct() {
$this->enfants = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* @return string
*/
public function getCode()
{
return $this->code;
}
/**
* @param string $code
*/
public function setCode($code)
{
$this->code = $code;
}
/**
* @return int
*/
public function getPositionAffichage()
{
return $this->positionAffichage;
}
/**
* @param int $positionAffichage
*/
public function setPositionAffichage($positionAffichage)
{
$this->positionAffichage = $positionAffichage;
}
/**
* Set nom
*
* @param string $nom
*
* @return Categorie
*/
public function setNom($nom)
{
$this->nom = $nom;
return $this;
}
/**
* Get nom
*
* @return string
*/
public function getNom()
{
return $this->nom;
}
/**
* Get nom complet
*
* @return string
*/
public function getNomComplet()
{
if ($this->parent)
{
return $this->parent->getNom() . " > " . $this-> nom;
}
return $this->nom;
}
/**
* Set parent
*
* @param Categorie $parent
*
* @return Categorie
*/
public function setParent($parent)
{
$this->parent = $parent;
return $this;
}
/**
* Get parent
*
* @return Categorie
*/
public function getParent()
{
return $this->parent;
}
/**
* @return mixed
*/
public function getEnfants()
{
return $this->enfants;
}
/**
* @param mixed $enfants
*/
public function setEnfants($enfants)
{
$this->enfants = $enfants;
}
public function __toString()
{
return "".$this->code;
}
}

任何人都有线索让我理解为什么删除这些Categorie实体吗？
谢谢！
