Question

我手动创建了一个评论表单，用户可以在其中评论某个事件：

<form action="{{ path('mql14mqlme_oneeventdisplay', { 'id': app.session.get('idevent') }) }}" method="post" id="commentform">
                        <h3 class="heading">LEAVE A REPLY</h3>


                        <textarea name="comment" id="comment"  tabindex="4"></textarea>

                        <p><input name="submit" type="submit" id="submit" tabindex="5" value="Post" /></p>


                    </form>

来自routing.yml的行动路线：

mql14mqlme_oneeventdisplay:
    pattern: /evenement/display/{id}
    defaults: { _controller: Mql14mqlmeBundle:Event:display}

来自控制器的动作：

public function displayAction($id,Request $request)
{
    $em = $this->container->get('doctrine')->getEntityManager();
    $evenements = $em->find('Mql14\mqlmeBundle\Entity\Evenement', $id);

$categories= $em->getRepository('Mql14mqlmeBundle:Categorie')->findAll();    
    $query1 = $this->container->get('doctrine')->getEntityManager()->createQuery( 'SELECT c FROM Mql14mqlmeBundle:Commentaire c' . ' JOIN c.evenement e  '  . ' WHERE e.id=:id' . ' ')
    ->setParameter('id', $id);
    $com=$query1->getResult();
     $ca=$evenements->getCategorie();

     $iduser = $this->get('session')->get('iduser');
     $user = $em->getRepository('Mql14mqlmeBundle:User')->find($iduser);

     //commentaire
     $session = $this->getRequest()->getSession();
     $session->set('idevent', $id);
     $idevent = $session->get('idevent');

     if ('POST' === $request->getMethod()) {
    $comment = $request->get('comment');

        $commentaire = new Commentaire();
        $commentaire->setContenu( $comment);
        $commentaire->setUser( $user);
        $commentaire->setEvenement( $evenements);

        $em->persist($commentaire);


     }

    return $this->render('Mql14mqlmeBundle:Default:singleevent.html.twig', array(
            'evenements' => $evenements,
            'categories' => $categories,
            'com'=>$com,
            'ca'=>$ca,
            'user'=>$user,

    ));
}

我希望在数据库中保留的实体Commentaire.php：

    <?php

    namespace Mql14\mqlmeBundle\Entity;

    use Doctrine\ORM\Mapping as ORM;

    /**

        }

        /**

        }

        {
            return $this->user;
        }

        public function setEvenement(\Mql14\mqlmeBundle\Entity\Evenement $evenement)
        {
            $this->evenement = $evenement;
        }

        /**

        public function getEvenement()

}

我没有收到任何错误，但评论未插入数据库。（在控制器中，idevent和iduser是我在整个项目中使用的两个会话变量）谢谢

请检查您是否进行了检查，然后闪烁。

$entityManager->persist($entity);
$entityManager->flush();

插入数据库symfony2
