Symfony 6.2 翻译错误'未定义表：7 错误：关系“ext_translations_id_seq”不存在'postgresSql

Question

我有一个控制器操作：

#[Route('/store', name: 'store', methods: 'POST')]
public function store(Request $request): Response
{
    $myEntity = new MyEntity();

    $form = $this->createForm(MyEntityFormType::class, $myEntity);

    $form->handleRequest($request);
    $form->submit($request->toArray());

    if ($form->isSubmitted()) {

        if ($form->isValid()) {
            /** @var MyEntity $validatedMyEntity */
            $validatedMyEntity = $form->getData();

            $this->doctrine->persist($validatedMyEntity);

            $this->doctrine->flush();

            $this->doctrine->refresh($validatedMyEntity);

            return $this->getJsonResponse($validatedMyEntity);
        }
    }
    elseif (!$form->isSubmitted()) {
        dd('not isSubmitted...');
    }

当我调用端点时，我在

$this->doctrine->flush();

行收到以下错误消息：

{
    "type": "https://tools.ietf.org/html/rfc2616#section-10",
    "title": "An error occurred",
    "status": 500,
    "detail": "An exception occurred in the driver: SQLSTATE[42P01]: Undefined table: 7 ERROR:  relation \"ext_translations_id_seq\" does not exist\nCONTEXT:  unnamed portal parameter $1 = '...'",
    "class": "Doctrine\\DBAL\\Exception\\TableNotFoundException",
    "trace": [
    .
    .
    .
        {
            "namespace": "Doctrine\\DBAL",
            "short_class": "Connection",
            "class": "Doctrine\\DBAL\\Connection",
            "type": "->",
            "function": "lastInsertId",
            "file": "/home/vagrant/Projects/tests/Trendency/vendor/doctrine/orm/lib/Doctrine/ORM/Id/IdentityGenerator.php",
            "line": 48,
            "args": []
        },
    .
    .
    .
    ]
}

有一件奇怪的事情，当我从命令调用它时，它运行良好。 我尝试启动

doctrine:shchame:validate

和

doctrine:shchame:update --force

命令，但没有任何效果。

额外

doctrine.orm.mappings

已在

doctrine.yaml

中如下：

            gedmo_translatable:
                type: attribute
                prefix: Gedmo\Translatable\Entity
                dir: "%kernel.project_dir%/vendor/gedmo/doctrine-extensions/src/Translatable/Entity"
                alias: GedmoTranslatable # (optional) it will default to the name set for the mapping
                is_bundle: false
            gedmo_translator:
                type: attribute
                prefix: Gedmo\Translator\Entity
                dir: "%kernel.project_dir%/vendor/gedmo/doctrine-extensions/src/Translator/Entity"
                alias: GedmoTranslator # (optional) it will default to the name set for the mapping
                is_bundle: false

形式为：

class MyEntityFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add(
                'id',
                UuidType::class,
                [
                    'required'          => false,
                ])
            ->add(
                'title',
                TextType::class,
                [
                    'required'          => true,
                    'constraints'       =>  [
                        new NotBlank(['message'=>'Add Title!']),
                        new NotNull(['message'=>'Title cannot be null!']),
                    ],
                    'invalid_message'   => "Bad title type"
                ]
            )
            ->add(
                'description',
                TextType::class,
                [
                    'required'          => true,
                    'constraints'       =>  [
                        new NotBlank(['message' =>'Add Description!']),
                        new NotNull(['message'  =>'Description cannot be null!']),
                    ],
                    'invalid_message'   => "Bad Description type"
                ]
            );
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class'        => MyEntity::class,
            'csrf_protection'   => false
        ]);
    }
}

我怀疑，这个错误与

stof/doctrine-extensions-bundle

或id的uuid类型有关，但由于在它的存储库中找不到这个字符串，所以没有其他想法可以解决。 有谁有想法，如何解决？ 感谢您提前提供帮助。

Answer 1

我找到了一个解决方法。

ext_translations_id_seq

名称是

stof/doctrine-extensions-bundle

gedmo_translator

特征中的序列名称。

我添加了动态表前缀逻辑，可以找到这里

不幸的是，这个表/序列不能与链接的 Doctrine 事件监听器很好地配合，所以我需要为 SEQUENCES 添加处理程序。

所以我也基于这个描述添加了一个SequencePrefixSubscriber。 之后，原始序列名称也带有前缀，除了

ext_translations_id_seq

之外，每个人都工作，因为持久期间的UnitOfWork会刷新该ClassMetaData，并在id生成期间搜索无前缀的序列名称。

为了处理它，我简单地为

Translation

和

AbstractTranslation

类创建了一个豁免案例，并使用此序列。这样以后就不会被覆盖，并且可以生成id。

这是完整的

loadClassMetadata()

方法：

public function loadClassMetadata(LoadClassMetadataEventArgs $eventArgs)
{
    /** @var ClassMetadata $classMetadata */
    $classMetadata = $eventArgs->getClassMetadata();

    if ($classMetadata->isIdGeneratorSequence())
    {
        $newDefinition = $classMetadata->sequenceGeneratorDefinition;
        $newDefinition['sequenceName'] = $this->prefix . $newDefinition['sequenceName'];

        $classMetadata->setSequenceGeneratorDefinition($newDefinition);
        $em = $eventArgs->getEntityManager();
        if (isset($classMetadata->idGenerator)) {
            $sequenceGenerator = new \Doctrine\ORM\Id\SequenceGenerator(
                $em->getConfiguration()->getQuoteStrategy()->getSequenceName(
                    $newDefinition,
                    $classMetadata,
                    $em->getConnection()->getDatabasePlatform()),
                $newDefinition['allocationSize']
            );
            $classMetadata->setIdGenerator($sequenceGenerator);
        }
    }

    if (in_array($classMetadata->getName(), [Translation::class, AbstractTranslation::class])) {
        $sequenceName = $this->prefix . self::STOF_TRANSLATION_SEQ_NAME;
        $idGenerator = new IdentityGenerator($sequenceName);
        $classMetadata->setIdGenerator($idGenerator);
    }
}

我只添加了 in_array 条件包裹的部分。

当然，展位订阅者和事件监听器应该在

services.yaml

中的服务索引下注册。
