Question

大家好我有一个查询有问题。我正在Symfony 2.7上构建应用程序，我想在存储库中进行查询，但是当我使它抛出异常时说：

未定义的方法'getDoctrine'。方法名称必须以findBy或findOneBy！
开头

以下是存储库中的代码：

namespace George\ObjectsBundle\Entity;

/**
 * ObjectRepository
 *
 * This class was generated by the Doctrine ORM. Add your own custom
 * repository methods below.
 */
class ObjectRepository extends \Doctrine\ORM\EntityRepository
{
public function getOggallery()
{
    $em = $this->getDoctrine()->getManager();
    $query = $this->createQuery("SELECT o, a FROM George\ObjectsBundle\Entity\Object  o JOIN o.ogallery a WHERE a.ord = 0");
    $objects = $query->getResult();

    return $objects;
}

}

但是当我在Controller方法中返回代码时，它可以工作。

 $query = $em->createQuery("SELECT o, a FROM George\ObjectsBundle\Entity\Object  o JOIN o.galleries a WHERE a.ord = 0");
 $objects = $query->getResult();

为什么此代码不能与存储库中的Doctrine Entity管理器一起使用？

您收到此错误是因为您正在调用不存在的存储库方法getDoctrine()。试试这个：

class ObjectRepository extends \Doctrine\ORM\EntityRepository
{
    public function getOggallery()
    {
        $em = $this->getEntityManager();
        $query = $this->createQuery("SELECT o, a FROM George\ObjectsBundle\Entity\Object  o JOIN o.ogallery a WHERE a.ord = 0");
        $objects = $query->getResult();

        return $objects;
    }    
}

存储库中的Symfony DQL查询
