更新查询 symfony2 出错

Question

我为正在工作的实体 Evenement(event) 生成了 CRUD。但是现在我想在每次添加 Evenement 时更新另一个名为 notification 的实体中的字段。每个晚上都有一个类别

Evenement.php：

<?php

namespace Mql14\mqlmeBundle\Entity;

在为 Evenement 实体执行 CRUD 后生成的 createAction 中，我添加了更新查询：

public function createAction(Request $request)
{
    $entity  = new Evenement();
    $request = $this->getRequest();
    $form    = $this->createForm(new EvenementType(), $entity);
    $form->bindRequest($request);
    $entity->upload();
  $cat=$entity->getCategorie();


if ($cat) {
    $catn = $cat->getNomCat();


$query = $this->container->get('doctrine')->getEntityManager()->createQuery( 'UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1  WHERE n.categorie LIKE :catn  ' );
          $query->setParameter('categorie', $catn);
            $query->execute();

  }
if ($form->isValid()) {
    $em = $this->getDoctrine()->getEntityManager();
    $em->persist($entity);
    $em->flush();

    return $this->redirect($this->generateUrl('mql14mqlme_adminshow', array('id' => $entity->getId())));

}

return array(
    'entity' => $entity,
    'form'   => $form->createView(),            
);

}

我得到的错误是：

[语义错误] 第 0 行，第 61 列，靠近“类别 LIKE”：错误： 无效的路径表达式。必须是 StateFieldPathExpression。

Answer 1

您在更新查询中设置了错误的参数。

在这一行：

$query = $this->container->get('doctrine')->getEntityManager()->createQuery(
         'UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1
         WHERE n.categorie LIKE :catn' );
      $query->setParameter('categorie', $catn);
        $query->execute();

应该是：

$query = $this->container->get('doctrine')->getEntityManager()->createQuery(
         'UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1
         WHERE n.categorie LIKE :catn' );
      $query->setParameter('catn', $catn);
        $query->execute();

Answer 2

n.categorie 是一个实体（Mql14\mqlmeBundle\Entity\Categorie 类型），您无法使用 LIKE 比较实体。

尝试将LIKE 替换为=。

改变

UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1 WHERE n.categorie LIKE :catn

到

UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1 WHERE n.categorie = :catn
