验证不适用于关系字段

Question

我有用户和文件之间的OnetoOne关系，问题是每次我通过嵌入表单发布新文件时验证都不起作用。
我试过在symfony中提到的这个解决方案doc为了防止验证对象嵌入作为被验证对象的属性，我们需要在第一个字段中添加@Assert \ Valid。
另外我试图验证一个字符串，而不是一个文件，这没有奏效。
顺便说一句，在用户类中提到的任何验证，工作正常。

Answer 1

我发现了一个slution但我仍然不知道为什么通过注释进行验证没有作用。 解决的办法是过时了验证通过formType限制：

/** 
    * {@inheritdoc} 
    */ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    {$builder-> 
     add('imageFile', 


      VichFileType::class, [ 



      'constraints' => array(
       new Image(array('minWidth' => 500,'minHeight' => 350,'mimeTypes'=> 
        array(
        'image/jpeg', 
        'image/png', 
        'image/jpg', 
        'image/gif', 
        ), 
        )), 
       new File(array('maxSize' => 1024000,'mimeTypes'=> 
        array(
        'application/pdf', 

        ),)),), 











'required' => false, 

      'allow_delete' => true, 
      'download_link' => true, 
      'label' => false, 

      ]); 

}
