Question

在我的控制器上应用验证方法时出现此错误。

捕获致命错误：传递给att \ Bundle \ Validator \ Constraint \ CertWfCheckValidator :: validate（）的参数2必须是Symfony \ Component \ Validator \ Constraint的实例，没有给出，在/ var / www / html /中调用第451行上的att / src / att / Bundle / Controller / CertificateController.php并定义了

这是我的服务定义：

    att.validator.certificate.wkcheck:
    class: att\Bundle\Validator\Constraint\CertWfCheckValidator
    arguments: ["@doctrine.orm.entity_manager", "@service_container"]
    tags:
        - { name: validator.constraint_validator, alias: validator.certwkcheck }

约束类：

namespace att\Bundle\Validator\Constraint;

use Symfony\Component\Validator\Constraint;


/**
 * @Annotation
 */
class CertWfCheck extends Constraint {

public $message = "El certificado tiene un Tramite asociado, no se puede eliminar";



public function validatedBy() {
    return 'validator.certwkcheck';
}

public function getTargets() {
    return [self::CLASS_CONSTRAINT];
}
}

验证员类：

namespace att\Bundle\Validator\Constraint;

use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;

class CertWfCheckValidator extends ConstraintValidator {

    protected $em;
    protected $container;

    public function __construct(\Doctrine\ORM\EntityManager $em, \Symfony\Component\DependencyInjection\ContainerInterface $container) {

        $this->em = $em;
        $this->container = $container;

    }

    public function validate($value, Constraint $constraint) {
        var_dump($value);
    }  
}

Controoller

   $certificate = $this->get('certificate.manager')
                    ->getCertificateById(
                            $this->getRequest()->request->get('id')
                            );

   $validator = $this->get('att.validator.certificate.wkcheck'); 
   $errors = $validator->validate($certificate);
   $errorsString = (string) $errors;

Answer 1

不要在Constraint类中的方法getTargets（）中返回数组，使其成为return self::CLASS_CONSTRAINT;

2和主要。查看您的Validator类，您可以定义方法＆＃34;验证＆＃34;有两个参数，但是当你调用这个方法时，你只提供一个参数 - $ value。所以你应该初始化你的约束类，并作为第二个参数传递给方法。像这样：

$certificate = $this->get('certificate.manager')
                    ->getCertificateById(
                            $this->getRequest()->request->get('id')
                            );

$validator = $this->get('att.validator.certificate.wkcheck');  
$constraint = new CertWfCheck();  
$errors = $validator->validate($certificate, $constraint);  
$errorsString = (string) $errors;

Answer 2

更新：我找到了解决方案调用验证服务。

$constraint = new \att\Bundle\Validator\Constraint\CertWfCheck;
$errors = $this->container->get('validator')
                ->validateValue(
                        $entity,
                        $constraint);

验证具有自定义验证约束的实体时出错
