问题描述
我在用户和文件之间有 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.
我尝试了 symfony doc 中提到的这个解决方案，以防止验证被嵌入作为正在验证的对象上的属性，我们需要在第一个字段中添加@Assert\Valid.
我也试图验证即使是字符串而不是文件，但这没有用.
顺便说一下，用户类中提到的任何验证都可以正常工作.
文件.php
I have OnetoOne relation between Users and Files, The problém is that every time i post a new file via embed form the validiation does not work .
I tried this solution mentioned in symfony doc To prevent validation on objects that are embedded as properties on an object being validated we need to add @Assert\Valid in the first filed.
Also i tried to validate even a string not a file and this didnt work.
By the way any validation mentioned in Users class, works fine.
Files.php

UsersType.php
UsersType.php
class UsersType extends AbstractType

/**

public function buildForm(FormBuilderInterface $builder, array $options)

$builder->
->add('cv',FilesType::class)
文件类型.php
/**

public function buildForm(FormBuilderInterface $builder, array $options)

$builder ->
add('imageFile',
VichFileType::class, [

'label' => false,
]);
}
推荐答案
我找到了一个解决方案，但我仍然不知道为什么通过注释进行的验证不起作用.解决方案是通过 formType 约束通过验证:
I found a solution but i still dont know why the validation via annotation didint work.The solution is to passe validation via formType constrains:
/**
* {@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,
]
);
}
