Symfony 删除FOSUserBundle错误消息

我正试图从我的表单中删除通用的FOSUserBundle消息

这是我出错时的结果：

我想删除红场上的消息。 正如你所看到的，我成功地发布了我自己的错误消息

我查看了大量其他论坛，但没有成功

这是我的密码：

• app/MDBUserBundle/views/Registration/register\u content.html（我覆盖了注册表表单）
  ContainsUserValidator.php

  <?php
  namespace MDB\UserBundle\Validator\Constraints;
  
  use Symfony\Component\Validator\Constraint;
  use Symfony\Component\Validator\ConstraintValidator;
  
  class ContainsUserValidator extends ConstraintValidator
  {
      protected $em;
  
      public function __construct(\Doctrine\ORM\EntityManager $em)
      {
          $this->em = $em;
      }
  public function validate($value, Constraint $constraint)
      {
          $repository     = $this->em->getRepository('MDBUserBundle:User');
          $user           = $repository->findOneByUsername($value);
  
          if ($user) {
              $this->context->addViolation(
                  $constraint->message,
                  array('%string%' => $value)
              );
  }}}
  

  因此，如果您有删除这些消息的想法，那就太好了：）

  提前感谢
  我认为您的约束与用户名的原始FOSUserBundle约束相同。您可能对Symfony没有什么经验，也不知道它在默认情况下已被禁用
  所有捆绑包的翻译文件都采用点符号（

  fos\u user.username.ready\u existed

  ）。您可以覆盖现有的翻译文件或使用您的语言环境添加新的翻译文件。在该文件中，您可以为所有约束设置所有消息

  如果你想禁用一些约束，你需要覆盖默认的

  验证

  文件。
  谢谢你，它工作起来很有魅力。确实，我对这个框架有一个小小的体验^^^^^再次谢谢
