php - 为什么我的 symfony 实体不受管理？

Question

我有一个 Portfolio 实体，它可以很好地创建或更新，但我无法删除它。 Symfony 抛出这个错误:

Entity matthieu-appriou is not managed. An entity is managed if its fetched from the database or registered as new through EntityManager#persist

这是我的实体:

下面是我用来重现此错误的代码示例:

<?php

// namespace and use ...

/**
 * Tool controller.
 *
 * @Route("/admin/test")
 */
class TestController extends Controller
{

  /**
   *
   * @Route("/testTwo", name="testTwo")
   * @Method({"GET", "POST"})
   */
  public function indexTwoAction(Request $request)
  {
    $em = $this->getDoctrine()->getManager();
    $pr = $this->get('creasenso.portfolio_repo');

    $p = $pr->find(32);

    $em->remove($p);
    $em->flush();


    return new Response("<html><head></head><body><hr />Done</body></html>");

  }

}

这是链接到该实体的存储库:

<?php

namespace CreasensoBundle\Repository;

use Doctrine\ORM\EntityRepository;

/**
 * PortfolioRepository
 *
 * This class was generated by the Doctrine ORM. Add your own custom
 * repository methods below.
 */
class PortfolioRepository extends EntityRepository
{

  protected $qb;


  public function init()
  {
    $this->qb = $this->createQueryBuilder('p');
  }

  public function isVisible()
  {
    $this->qb
      ->andWhere('p.visible = :visible')
      ->setParameter(':visible', 1);
  }

  public function getAllPublicPortfolioCount()
  {
    $this->init();
    $this->isVisible();
    $this->qb->select('COUNT(p)');

    return $this->qb->getQuery()->getSingleScalarResult();
  }

  public function getQueryBuilder()
  {
    return $this->qb;
  }

}

您对这种行为有任何线索吗？非常感谢。

当您应该通过 getRepository() 从 EntityManager 获取存储库时，您直接从服务容器获取存储库。

您没有从刷新的 entityManager 加载您的实体，因此它不受管理
