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

Question

我目前正在使用Symfony2,我收到此错误消息:

未定义的方法'getDoctrine'.方法名称必须以findBy或findOneBy开头!500内部服务器错误 - BadMethodCallException

这是我的实体类:

 <?php

namespace Gestionresiduos\ResiduoBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
* @ORM\Entity(repositoryClass="ResiduoRepository")
*/

class BodegaContieneResiduo
{


    /**
    * @ORM\Id
    * @ORM\column(type="integer")
    * @ORM\GeneratedValue
    */

    protected $idContiene;

.....

}

这是Controller的页面Action方法:

 <?php

namespace Gestionresiduos\ResiduoBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class DefaultController extends Controller
{
    public function portadaAction()
    {
        $em = $this->getDoctrine()->getEntityManager();

        $ofertas= $em->getRepository('ResiduoBundle:BodegaContieneResiduo')->findResiduosAlmacenados();
        return $this->render('ResiduoBundle:Default:index.html.twig');
    }
}

这是我的EntityRepository:

    <?php
namespace Gestionresiduos\ResiduoBundle\Entity;

use Doctrine\ORM\EntityRepository;

class ResiduoRepository extends EntityRepository
{

    public function findResiduosAlmacenados()
    {
        $em = $this->getDoctrine()->getEntityManager();
        $consulta = $em->createQuery('SELECT r FROM ResiduoBundle:BodegaContieneResiduo');
        return $consulta->getOneOrNullResult();
    }
}

我也试过在这一切的解决方案后的蝎子,这后由K-亚历克斯

那么,问题在哪里？

Answer 1

在Repository类中,而不是:

$em = $this->getDoctrine()->getEntityManager();

你应该使用:

$em = $this->getEntityManager();
