问题描述
您好，我正在尝试验证用户实体验证，但是只有一个属性与PATCH请求一起使用，但是我却得到了Cannot validate values of type \"NULL\" automatically. Please provide a constraint.
即使从validation_groups中删除默认值，我也得到相同的结果
非常感谢您的帮助。

App \ Controller \ PayingMembershipForOthersController
namespace App\Controller;
use ApiPlatform\Core\Validator\ValidatorInterface;
use App\Entity\User;
use Symfony\Component\HttpFoundation\Request;
class PayingMembershipForOthersController
{
private ValidatorInterface $validator;
public function __construct(ValidatorInterface $validator)
{
$this->validator = $validator;
}
public function __invoke(User $data,Request $request)
{
$this->validator->validate($data);
}
}
因此，我故意将空值{"payForNewMember": ""}设置为不显示违规列表
解决方法
您的自定义控制器必须返回用户或响应。
class PayingMembershipForOthersController
{
private ValidatorInterface $validator;
public function __construct(ValidatorInterface $validator)
{
$this->validator = $validator;
}
public function __invoke(User $data)
{
$this->validator->validate($data);
return $data;
}
}
