Question

我目前在Symfony验证器上遇到问题可选约束。

我需要仅在传递了该字段时才处理parentId规则（密钥在ParameterBag中），不幸的是，Symfony总是尝试验证，即使它没有被传递。

public function validateParameters(ParameterBag $request, Collection $validatorRules)
{
    $validatorErrors = $this->validator->validateValue($request->all(), $validatorRules);
    if (count($validatorErrors) !== 0) {
        throw new \Exception($validatorErrors[0]->getPropertyPath() . ' - ' . $validatorErrors[0]->getMessage());
    }
    echo 'yay!';
    exit;
}

public function create(Application $app, Request $request)
{
    // check that the validation rules pass for this service
    $this->validateParameters($request->request, new Collection([
        'parentId'    => [new Assert\Optional(), new Assert\Regex(['pattern' => '/^[0-9]\d*$/'])],
        'title'       => [new Assert\NotBlank(), new Assert\Length(['min' => 3])],
        'description' => [new Assert\NotBlank()],
    ]));
    // ...............
}

任何帮助或指针都会受到高度赞赏，因为Symfony文档主要讨论直接验证对象，但我想验证参与的ParameterBag。

这应该有效

public function create(Application $app, Request $request)
{
    // check that the validation rules pass for this service
    $this->validateParameters($request->request, new Collection([
        'parentId'    => new Assert\Optional([
            new Assert\Regex(['pattern' => '/^[0-9]\d*$/'])
        ]),
        'title'       => [
            new Assert\NotBlank(), 
            new Assert\Length(['min' => 3])
        ],
        'description' => new Assert\NotBlank(),
    ]));
    // ...............
}

Symfony可选约束无法按预期工作
