Symfony 2：如何覆盖另一个捆绑包的存储库

我有2个bundle，我想覆盖其中一个bundle在另一个bundle中的存储库：

我有一个源包：SourceBundle。 我有我的覆盖包：覆盖包

首先，在我们的vendoroverridebundle.php中，我添加了：

public function getParent()
{
    return 'SomeVendorSourceBundle';
}

然后

我想为SourceBundle实体的存储库添加一个自定义方法。 源实体是Response.php，其存储库是ResponseRepository.php

所以我做了：

<?php
namespace OurVendor\OverrideBundle\Repository;
use Doctrine\ORM\EntityRepository;
use SomeVendor\SourceBundle\Repository\ResponseRepository as BaseRepository;

class ResponseRepository extends BaseRepository
{
    /**
     *
     * @return array
     */
    public function getQueryExerciseAllResponsesForAllUsers($exoId)
    {
        $qb = $this->createQueryBuilder('r');
        $qb->join('r.paper', 'p')
            ->join('p.exercise', 'e')
            ->where('e.id = ?1')
            ->andWhere('p.interupt =  ?2')
            ->setParameters(array(1 => $exoId, 2 => 0));
        return $qb->getQuery();
    }
}

SourceBundle实体是：

<?php
namespace SomeVendor\SourceBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
 * SomeVendor\SourceBundle\Entity\Response
 *
 * @ORM\Entity(repositoryClass="SomeVendor\SourceBundle\Repository\ResponseRepository")
 * @ORM\Table(name="source_response")
 */
class Response
{
  ... 
}

似乎找不到表中的字段。所以我换了

<?php
namespace OurVendor\OverrideBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use SomeVendor\SourceBundle\Entity\Response as BaseEntity;
/**
 * SomeVendor\SourceBundle\Entity\Response
 *
 * @ORM\Entity(repositoryClass="OurVendor\OverrideBundle\Repository\ResponseRepository")
 * @ORM\Table(name="source_response")
 */
class Response extends BaseEntity
{
    public function __construct()
    {
        parent::__construct();
    }
}

---

另一个捆绑包中的原则映射可以在实体类元数据加载时重写

事件监听器

<?php
namespace OurVendor\OverrideBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use SomeVendor\SourceBundle\Entity\Response as BaseEntity;
/**
 * SomeVendor\SourceBundle\Entity\Response
 *
 * @ORM\Entity(repositoryClass="OurVendor\OverrideBundle\Repository\ResponseRepository")
 * @ORM\Table(name="override_response")
 */
class Response extends BaseEntity
{
    public function __construct()
    {
        parent::__construct();
    }
}
