如何使用 ServiceEntityRepository 刷新实体加载

Question

我已经使用 Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository 加载了一个实体（SF4 中的新建议），我想刷新这个实体。

但是$entityManager->clear() 不做这项工作并且

$entityManager->refresh($myentity) 

告诉我

Doctrine\ORM\ORMInvalidArgumentException：实体 App\Entity\MyEntity@0000000068ed8bf0000000007dca9dd1 不受管理。如果实体从数据库中获取或通过 EntityManager#persist 注册为新实体，则该实体被管理

这是我的仓库：

    <?php

    namespace App\Core\Repository;

    use App\Core\Entity\Question;
    use App\Core\Entity\QuestionnaireResponse;
    use App\Core\Entity\Reponse;
    use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
    use Symfony\Bridge\Doctrine\RegistryInterface;

    /**
     * @method Reponse|null find($id, $lockMode = null, $lockVersion = null)
     * @method Reponse|null findOneBy(array $criteria, array $orderBy = null)
     * @method Reponse[]    findAll()
     * @method Reponse[]    findBy(array $criteria, array $orderBy = null, $limit = null, $offset = null)
     */
    class ReponseRepository extends ServiceEntityRepository
    {
        /**
         * ReponseRepository constructor.
         * @param RegistryInterface $registry
         */
        public function __construct(RegistryInterface $registry)
        {
            parent::__construct($registry, Reponse::class);
        }

    }

这是我的测试设置：

        $executor = new ORMExecutor($em, $purger);
        $executor->execute($loader->getFixtures());

        $this->em = $em;
        $this->application = $application;
        return ;

    }
}

这是我尝试清除数据的测试。

    }

        $client = static::createClient(

        $questionnaire =  $this->em->getRepository(Questionnaire::class)->findSystemAndValue('system', '123');

        $crawler = $client->request(
            'GET',

        );
        $response = $client->getResponse();
        $this->assertEquals(200, $response->getStatusCode());

        $form = $crawler->selectButton('appbundle_questionnaire_display[draft]')->form();
        $form['appbundle_questionnaire_display[1]'] = 0;
        $form['appbundle_questionnaire_display[2]'] = 1;
        $crawler = $client->submit($form);

        $this->assertEquals(302, $response->getStatusCode());

        // vérification de l'état de la base de données

        $questionnaireResponse = $this->em->getRepository(QuestionnaireResponse::class)->find(1);

        );
        $response = $client->getResponse();

        $this->assertEquals(200, $response->getStatusCode());

        $this->assertEquals(0, $crawler->filter('form[name="appbundle_questionnaire_display"]')->form()->getValues()['appbundle_questionnaire_display[1]'], 'cas2.1');
        $this->assertEquals(1, $crawler->filter('form[name="appbundle_questionnaire_display"]')->form()->getValues()['appbundle_questionnaire_display[2]'], 'cas2.2');

        $form = $crawler->selectButton('appbundle_questionnaire_display[submit]')->form();

        $crawler = $client->submit($form);

        $response = $client->getResponse();
        $this->assertEquals(302, $response->getStatusCode());

        $this->em->refresh($reponse1);
        $this->em->refresh($reponse2);
        $this->em->refresh($questionnaireResponse);
        //$this->em->clear();

        $this->assertEquals('1', $this->em->getRepository(Reponse::class)->find(1)->getValeur(), 'cas3.1');
        $this->assertEquals('0', $this->em->getRepository(Reponse::class)->find(2)->getValeur(), 'cas3.2');
        $this->assertEquals(3, $this->em->getRepository(QuestionnaireResponse::class)->find(1)->getVersionId());
    }
}

我该怎么做？

Answer 1

我找到了解决办法。

我在 TestSetUp 中获得的 entityManager 不是 ServiceEntityRepository 使用的那个。这是由于 ServiceEntityRepository 的构造造成的。

Si 要清除良好的 entityManager，我必须在 Repository 上调用 clear，而不是在我的 EntityManger 上：

public function test_BrouillonPuisSoumission()
    {

        // ...

        // vérification de l'état de la base de données
        $reponseRepository =  $this->em->getRepository(Reponse::class);
        $questionnaireResponseRepository = $this->em->getRepository(QuestionnaireResponse::class);
$this->em->getRepository(QuestionnaireResponse::class)->find(1)->getVersionId());
        $this->assertEquals('0', $reponseRepository->find(1)->getValeur(), 'cas1.1');
        $this->assertEquals('1', $reponseRepository->find(2)->getValeur(), 'cas1.2');
        $this->assertEquals(2, $questionnaireResponseRepository->find(1)->getVersionId());


        // ...

        $reponseRepository->clear();
        $questionnaireResponseRepository->clear();

        $this->assertEquals('1', $reponseRepository->find(1)->getValeur(), 'cas3.1');
        $this->assertEquals('0', $reponseRepository->find(2)->getValeur(), 'cas3.2');
        $this->assertEquals(3, $questionnaireResponseRepository->find(1)->getVersionId());
    }

Answer 2

Doctrine/ORM/EntityManager::clear()方法

清除 EntityManager。当前由该 EntityManager 管理的所有实体都将分离。

Doctrine/ORM/EntityManager::refresh()方法

刷新数据库中实体的持久状态，覆盖任何尚未持久的本地更改。

要刷新实体，只需执行以下操作：

$entityManager->refresh($myentity)

没有 clear() 在它之前，删除它。
