Symfony2.8项目 通过注释NOT YML进行子表单验证 没有实体或学说参与
主窗体通过注释确认。收集字段，子表单无法验证。无论您输入什么内容，当主表单字段有效时，子表单中的每个字段都将作为有效字段传递。
我在网上尝试了很多建议，
＆＃39; error_bubbling＆＃39;，＆＃39; cascade_validation＆＃39;以及@Valid（）标记。什么都行不通。
我已将var_dump（...）添加到symfony2代码库中的RangeValidator类，并且未创建/调用它。为了证明它没有被使用，我将一个子表单字段复制到主表单，然后调用框架的验证程序进行范围检查，它应该对子表单中的某些字段执行，而不是。
显然有更多的代码，包括客户端javascript，但下面是一个基本的代码片段（从我的代码中挖出了这个问题）：
Main form:
class SubsetAdd extends AbstractType
{
/**

*
* @Assert\NotBlank(
* message="Subset name should not be blank"
* )
* @Assert\Regex(

* )
*/

/**

* pattern="/^[\d]{1,4}[Kk]{1}$/",
* message="Baud rate should be <n>K"
* )

/**

如何使用'constraints'=＆gt;新的有效（）？
$builder->add('entries', Type\CollectionType::class, array(
'constraints' => new Valid(),
'label' => 'Entries',
'type' => Module\EntryType::class,
'allow_add' => true,
'allow_delete' => true,
'required' => true,
'prototype' => true,
'prototype_name' => 'entries__name__',
));
