API 平台 "Unable to generate an IRI for an entity"

Question

我已经使用 symfony 6 创建了一个 API，并且我正在使用 api 平台进行过滤。我有 12 个实体运行良好，但有一个向我抛出错误。

这是执行 GET 请求时的错误：

Unable to generate an IRI for \"App\Entity\Titols\"."

这是 Titols 实体：

    }
}

这是我拥有的唯一实体，其中 id 不是数字而是字符串，这可能是问题所在吗？

这是TitolsController.php中的getAll函数来获取数据：

    /**
     * @Route("/api/titols", methods={"GET"})
     */
    public function getAll(TitolsRepository $titolsRepository): Response
    {
        $this->denyAccessUnlessGranted(TitolsVoter::VIEW);

        $titols = $titolsRepository->findBy([], ['codi' => 'ASC'], 10);

        return $this->json($titols);
    }

Answer 1

我终于没有使用我拥有的自定义控制器，我添加了 GET request，正如 api 平台在文档中所说：

#[ApiResource(
    attributes: ["security" => "is_granted('PERMISSION_TITOL')"],
    collectionOperations: [
        'get' => ['method' => 'get'],
    ],
    itemOperations: [
        'get' => [
            'path' => '/api/titols'            
        ],
    ],
)]

这解决了错误 Unable to generate an IRI for \"App\Entity\Titols\"."
