Symfony2-验证不适用于嵌入式表单类型 [英] Symfony2 - Validation not working for embedded Form Type

问题描述

我有一个结合了两个实体(用户和个人资料)的表单.

I have a form that combines two entities (User and Profile).

验证似乎在用户实体形式的表单的第一部分上起作用，并且是表单的基础.

Validation seems to work on the first part of the form that comes form the User Entity and is the basis of the form.

ProfileType包含在UserType中.该表单可以正确呈现并显示正确的信息，因此它似乎已正确连接到Profile实体.只是在ProfileType上被破坏的验证.

The ProfileType is included inside the UserType. The form renders correctly and displays the correct information, so it seems it is properly connected to the Profile entity. It's just the validation that is broken on the ProfileType.

关于为什么一部分可以验证而另一部分不能验证的任何想法吗?

Any idea as to why one part would validate and the other wouldn't?

以下代码:

Validation.yml

Validation.yml

DEMO\DemoBundle\Entity\User\Profile:
    properties:
        address1:
            - NotBlank: { groups: [profile] }
        name:
            - NotBlank: { groups: [profile] }
        companyName:
            - NotBlank: { groups: [profile] }

DEMO\DemoBundle\Entity\User\User:
    properties:
        username:
            - NotBlank:
                groups: profile
                message: Username cannot be left blank.
        email:
            - NotBlank:
                groups: profile
                message: Email cannot be left blank
            - Email:
                groups: profile
                message: The email "{{ value }}" is not a valid email.
                checkMX: true
        password:
            - MaxLength: { limit: 20, message: "Your password must not exceed {{ limit }} characters." }
            - MinLength: { limit: 4, message: "Your password must have at least {{ limit }} characters." }
            - NotBlank: ~

$user = $this->get('security.context')->getToken()->getUser();

        $form = $this->createForm(new UserType(), $user);

        if ($request->getMethod() == 'POST') {
            $form->bindRequest($request);

            if ($form->isValid()) {
                // Get $_POST data and submit to DB
                $em = $this->getDoctrine()->getEntityManager();
                $em->persist($user);
                $em->flush();

                // Set "success" flash notification
                $this->get('session')->setFlash('success', 'Profile saved.');
            }

        }

        return $this->render('DEMODemoBundle:User\Dashboard:profile.html.twig', array('form' => $form->createView()));

推荐答案

我花了很长时间进行搜索，发现它正在将'cascade_validation' => true添加到我的父类型的类中的setDefaults()数组中，该数组对其进行了修复(如已经在线程).这将导致实体约束验证触发表单中显示的子类型.例如

I spent an age searching and found that it was adding 'cascade_validation' => true to the setDefaults() array in my parent type's class that fixed it (as mentioned already in the thread). This causes the entity constraint validation to trigger in the child types shown in the form. e.g.

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(            
        ...
        'cascade_validation' => true,
    ));
}

对于集合，还请确保将'cascade_validation' => true添加到表单上集合字段的$options数组中.例如

For collections, also make sure to add 'cascade_validation' => true to the $options array for the collection field on the form. e.g.

$builder->add('children', 'collection', array(
    'type'         => new ChildType(),
    'cascade_validation' => true,
));

这将在集合中使用的子实体中进行唯一实体"验证.

This will have the UniqueEntity validation take place as it should in the child entity used in the collection.
