如何通过 Api-Platform 中的链接 属性 过滤结果?

How to filter results by a linked property in Api-Platform?

我有一个 User 实体和一个 Organisation 实体,BookingUser 之间存在关系 ManyToOne:

/**
 * @ORM\ManyToOne(targetEntity="App\Entity\User", inversedBy="bookings")
 * @ORM\JoinColumn(nullable=false)
 */
private $user;

User 实体有一个名为 属性 的国家/地区。我想将预订设置为仅显示与登录用户具有相同国家/地区的用户所做的记录。这是我试过的

collectionOperations={
*          "get"={
*              "access_control"="object.getUser().getOrganisation() == user.organisation"
*              "normalization_context"={
*                  "groups"={"read"}
*              }
*          },

当然不行

我知道我可以过滤查询字符串中传递的参数,但我需要在 API 端而不是客户端过滤这些结果。

Security page of the docs 上说:

Filtering collections according to the role or permissions of the current user must be done directly at the data provider level. For instance, when using the built-in adapters for Doctrine ORM, MongoDB and ElasticSearch, removing entries from a collection should be done using extensions.

查看 extensions,您需要执行以下操作:

final class BookingOwnerExtension implements QueryCollectionExtensionInterface
{
    private $security;

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

public function applyToCollection(QueryBuilder $queryBuilder, QueryNameGeneratorInterface $queryNameGenerator, string $resourceClass, string $operationName = null)
    {
        if (Booking::class !== $resourceClass || $this->security->isGranted('ROLE_ADMIN') || null === $user = $this->security->getUser()) {
            return;
        }

        $organization = $user->getOrganization()

        $rootAlias = $queryBuilder->getRootAliases()[0];
        $queryBuilder
            ->leftJoin(sprintf('%s.user', $rootAlias), 'u')
            ->andWhere('user.organization = :organization')
            ->setParameter('organization', $organization);
    }
}

(确切的查询将取决于您打算做什么,因为我不熟悉您的应用程序,所以我只能为您指明正确的方向。但这只是使用查询生成器)。

这很有可能,但如果您不使用自动配置,则必须使用适当的标签注册自定义扩展:

# api/config/services.yaml
services:
    # ...

    'App\Doctrine\BookingOwnerExtension':
        tags:
            - { name: api_platform.doctrine.orm.query_extension.collection }
