交响乐2 : how to override repository of another bundle

Question

我有 2 个 bundle ，我想覆盖其中一个 bundle 的存储库:

我有一个源包:SourceBundle。我有我的覆盖包:OverrideBundle

首先，在 OurVendorOverrideBundle.php 中，我添加了:

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

然后

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

所以我做到了:

<?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();
    }
}

如果我没有在 OverrideBundle 中设置实体，则会出现此错误:

The autoloader expected class "CPASimUSante\ExoverrideBundle\Entity\Response" to be defined in file "/home/www/myproject/vendor/ourvendor/override-bundle/OurVendor/OverrideBundle/Entity/Response.php". The file was found but the class was not in it, the class name or namespace probably has a typo.

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
{
  ... 
}

所以我在 OverrideBudle 中添加实体:

<?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();
    }
}

但是我遇到了这个错误:

An exception occurred while executing 'SELECT u0_.id AS id0, u0_.ip AS ip1, u0_.mark AS mark2, u0_.nb_tries AS nb_tries3, u0_.response AS response4, u0_.paper_id AS paper_id5, u0_.interaction_id AS interaction_id6 FROM ujm_exoverride_response u1_ INNER JOIN ujm_paper u2_ ON u0_.paper_id = u2_.id INNER JOIN ujm_exercise u3_ ON u2_.exercise_id = u3_.id WHERE u3_.id = ? AND u2_.interupt = ?' with params ["1", 0]:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'u0_.id' in 'field list'

这似乎没有找到表中的字段。所以我改为

<?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();
    }
}

它成功了。

...但是当我重新安装 bundle 时，为了测试一切是否正常，我遇到了这个 fatal error ，指出source_response已经定义(确实如此) .

那么我能做什么呢？

我还读到，除非源扩展 MappedSuperclass，否则我无法覆盖实体，在我的情况下，它不会。

但如果我只想覆盖它的存储库，我就注定失败了？是否可以 ？如果是这样，正确的方法是什么？

如果我完全删除覆盖实体的注释，我有:

Class "OurVendor\OverrideBundle\Entity\Response" sub class of "SomeVendor\SourceBundle\Entity\Response" is not a valid entity or mapped super class.
500 Internal Server Error - MappingException

可以在实体类元数据加载时覆盖另一个包中的学说映射。

事件监听器

<?php

namespace Lol\RandomBundle\EventListener;

use Doctrine\ORM\Event\LoadClassMetadataEventArgs;

class ClassMetadataListener
{
    /**
     * Run when Doctrine ORM metadata is loaded.
     *
     * @param LoadClassMetadataEventArgs $eventArgs
     */
    public function loadClassMetadata(LoadClassMetadataEventArgs $eventArgs)
    {
        $classMetadata = $eventArgs->getClassMetadata();

        if ('AnotherLol\AnotherRandomBundle\Entity\Response' === $classMetadata->name) {
            // Do whatever you want...
            $classMetadata->customRepositoryClassName = 'ThirdLol\SomeBundle\Repository\NewResponseRepository';
        }
    }
}

服务配置

services:
    lol.random.listener.class_metadata:
        class: Lol\RandomBundle\EventListener\ClassMetadataListener
        tags:
            -  { name: doctrine.event_listener, event: loadClassMetadata }
