Symfony 2表单：实体构件与多对一/一对多关系 - 关系不坚持

Question

我有一个审计表单，我可以附上几个资源（审计有很多资源，资源只附加到一个审计）。

表单在视图中很好地呈现，但是在保存表单时，所选的资源不会附加到数据库中的审计中。

审核表：

>add('ressources', 'entity', array(
      'class' => 'SpriMonitorBusinessBundle:Ressource', 
      'query_builder' => $this->em->getRepository('SpriMonitorBusinessBundle:Ressource')->getAvailableRessources(true), 
      'multiple'=>true 
    )) 

Audit.orm.yml：

oneToMany: 
    ressources: 
     targetEntity: Ressource 
     mappedBy: audit 

Ressource.orm.yml：

manyToOne: 
    audit: 
     targetEntity: Audit 
     inversedBy: ressources 
     joinColumn: 
     name: audit_id 
     referencedColumnName: id 

注：在的ressource形式时，我选择一个审核，它被正确保存

控制器：

public function newAction() 
    { 
     $em = $this->getDoctrine()->getEntityManager(); 
     $item = AuditFactory::make(); 
     $form = $this->createForm(new AuditType($em),$item); 

     $request = $this->get('request'); 
     $session = $this->get('session'); 

     if ('POST' == $request->getMethod()) { 
      try { 

       $this->validateForm($form,$request); 
       $em->persist($item); 
       $em->flush(); 
       $message = $this->container->getParameter('form_submit_success'); 
       $session->setFlash('success', $message); 
       $url = $this->generateUrl('Spri_audit_list'); 

       return $this->redirect($url); 

      } catch (FormException $e) { 
       $session->setFlash('error', sprintf('Erreur Formulaire : "%s"',$e->getMessage())); 
      } catch (\Exception $e) { 
       die(var_dump($e->getMessage())); 
       $session->setFlash('error', sprintf('Erreur inconnue ! Contactez l\'ADMIN'.$e->getMessage())); 
      } 
     } 

     return $this->render('SpriAuditBundle:Audit:new.html.twig', array('form'=>$form->createView())); 
    } 

    protected function validateForm($form, $request) 
    { 
     $form->bind($request); 
     if (!$form->isValid()) { 
      $message = $this->container->getParameter('form_submit_error'); 
      throw new FormException($message); 
     } 
    } 

的var_dump（$项目）显示：

private 'slug' => null 
    private 'ressources' => 
    object(Doctrine\Common\Collections\ArrayCollection)[4190] 
     private '_elements' => 
     array 
      0 => 
      object(Spri\MonitorBusinessBundle\Entity\Ressource)[3766] 
       ... 
    privat... 

任何想法？

好吧，我想我知道发生了什么事情。

public function newAction() 
{ 
    $em = $this->getDoctrine()->getEntityManager(); 
    $item = AuditFactory::make(); 
    $form = $this->createForm(new AuditType($em),$item); 

    $request = $this->get('request'); 
    $session = $this->get('session'); 

    if ('POST' == $request->getMethod()) { 
     try { 

      $this->validateForm($form,$request); 

      $newItem = $form->getData(); 

      $em->persist($newItem); 
      $em->flush(); 
      $message = $this->container->getParameter('form_submit_success'); 
      $session->setFlash('success', $message); 
      $url = $this->generateUrl('Spri_audit_list'); 

      return $this->redirect($url); 

     } catch (FormException $e) { 
      $session->setFlash('error', sprintf('Erreur Formulaire : "%s"',$e->getMessage())); 
     } catch (\Exception $e) { 
      die(var_dump($e->getMessage())); 
      $session->setFlash('error', sprintf('Erreur inconnue ! Contactez l\'ADMIN'.$e->getMessage())); 
     } 
    } 

    return $this->render('SpriAuditBundle:Audit:new.html.twig', array('form'=>$form->createView())); 
} 

Answer 2

必须设置在Ressource实体Audit实体手动编辑实体addRessource()方法：这个更新的控制器应解决您的问题。

只要编辑这个方法，如：

public function addRessource(Ressource $ressource) 
{ 
    $this->ressources[] = $ressource; 
    $ressource->setAudit($this); 

    return $this; 
} 

UPD

然后尝试在控制器手动坚持ressources：

foreach ($audit->getRessources() as $ressource) { 
    $em->persist($ressource); 
} 

UPD

好，奇怪。执行下一个代码片段并检查信源关系：

$em = $this->getDoctrine()->getManager(); 

$ressource = new Ressource(); 
$ressource->setSomeRequiredFieldValue($someValue); 

$audit = new Audit(); 
$audit->setSomeRequiredFieldValue($someValue); 
$audit->addRessource($ressource); 

$em->persist($audit); 
$em->persist($ressource); 
$em->flush();
