使用 API 平台的原则扩展 - SQL

Question

我正在开发一些 API 平台项目。 我正在使用我的 API 点 /references 来获取一些包含子实体的数据。

但问题是我使用 Doctrine 扩展来过滤我的列表。使用这个扩展，我可以过滤我得到的引用。

但是在子实体 Stock 中我仍然有一些我不想要的数据。

我的目标是获得所有拥有warehouse.owner = $owner 的股票。

代码如下：

private function addWhere(QueryBuilder $queryBuilder, string $resourceClass): void
{
    if ($this->security->isGranted('SCOPE admin') || !$this->security->isGranted('SCOPE logistician')) {
        return;
    }
    /** @var Client $client */
    $client = $this->security->getUser();
    $rootAlias = $queryBuilder->getRootAliases()[0];
    switch ($resourceClass) {
        case Entry::class:
        case Inventory::class:
            $queryBuilder->join(sprintf('%s.stock', $rootAlias), 's');
            break;
        case Reference::class:
            // I'm here
            $queryBuilder->join(sprintf('%s.stocks', $rootAlias), 's');
            break;
        default:
            return;
            break;
    }
    $queryBuilder->join('s.warehouse', 'w', Expr\Join::WITH, 'w.owner = :owner');
    $queryBuilder->setParameter('owner', $client->getSubject());
}

这是回复：

如何仅使用我的扩展程序和 DQL 过滤子实体结果？谢谢

扩展用于检索主要项目，而不是关联的集合。

您可以使用数据转换器。

class ReferenceOutput {
    public $stocks;
}

//Next class
use ApiPlatform\Core\DataTransformer\DataTransformerInterface;
use Symfony\Component\Security\Core\Security;

class ReferenceOutputTransformer implements DataTransformerInterface
{
    private string $security;

    public function __construct(Security $security)
    {
        $this->security = $security;
    }

    /**
     * Transforms the given object to something else, usually another object.
     * This must return the original object if no transformations have been done.
     *
     * @param object $object Snapshot
     *
     * @param string $to
     * @param array $context
     *
     * @return object
     */
    public function transform($object, string $to, array $context = [])
    {
        /** @var Reference $reference */
        $reference = $object;

        /** @var Client $client */
        $client = $this->security->getUser();

        $referenceOutput = new ReferenceOutput();
        $stocks = $reference->getStoks()->filter(
            static function($key, $stock) use ($client) {
            return $stock->getWarehouse()->getOwner() === $client->getSubject();
        });

        $referenceOutput->stocks = $stocks;

        return $referenceOutput;
    }

    /**
     * Checks whether the transformation is supported for a given data and context.
     *
     * @param object|array $data object on normalize / array on denormalize
     *
     * @param string $to
     * @param array $context
     *
     * @return bool
     */
    public function supportsTransformation($data, string $to, array $context = []): bool
    {
        return ReferenceOutput::class === $to && $data instanceof Reference;
    }
}
