我有一个Portfolio实体正在创建或更新，但我无法将其删除。 Symfony抛出了这个错误：
实体matthieu-appriou不受管理。如果实体是管理的 从数据库中提取或注册为新的 的EntityManager＃坚持

以下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>");
}
}
以下是链接到此实体的存储库：
<?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;
}
}
你对这种行为有什么线索吗？非常感谢你。
答案 0 :(得分：2)
当您从EntityManager通过getRepository()获取存储库时，您将直接从服务容器获取存储库。
您没有从您刷新的entityManager加载您的实体，因此它不受管理
