要恢复软删除的元素，你可以按照以下步骤使用 ApiPlatform：

1. 在你的实体类中，添加一个布尔类型的软删除字段，例如 isDeleted，用于标记是否已删除。

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class YourEntity
{
    // ...

    /**
     * @ORM\Column(type="boolean")
     */
    private $isDeleted = false;

    // ...

    public function getIsDeleted(): ?bool
    {
        return $this->isDeleted;
    }

    public function setIsDeleted(bool $isDeleted): self
    {
        $this->isDeleted = $isDeleted;

        return $this;
    }
}

2. 在你的控制器中，创建一个用于恢复软删除的操作。

use App\Entity\YourEntity;

/**
 * @Route("/your_entity/{id}/restore", name="your_entity_restore", methods={"PUT"})
 */
public function restoreYourEntity(YourEntity $yourEntity): JsonResponse
{
    $yourEntity->setIsDeleted(false);
    $this->getDoctrine()->getManager()->flush();

    return $this->json('Your entity has been restored.');
}

3. 在 ApiPlatform 的配置文件中，添加一个自定义操作。

# config/packages/api_platform.yaml
api_platform:
    # ...

    operations:
        restore:
            method: 'PUT'
            path: '/your_entity/{id}/restore'
            controller: App\Controller\YourEntityController::class.'::restoreYourEntity'
            formats: [ 'json' ]
            openapi_context:
                summary: 'Restore a soft-deleted YourEntity'
                description: 'Restore a soft-deleted YourEntity by setting isDeleted to false.'
                parameters:
                    - name: 'id'
                      in: 'path'
                      required: true
                      schema:
                          type: 'string'
                responses:
                    '200':
                        description: 'Your entity has been restored.'

现在，你可以向 /your_entity/{id}/restore 发送 PUT 请求来恢复软删除的元素。
