我有一个结合两个实体(用户和个人资料)的表单。

验证似乎适用于来自用户实体的表单的第一部分，并且是表单的基础。

ProfileType 包含在 UserType 中。表单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 ProfileType 上的验证被破坏了。

知道为什么一部分会验证而另一部分不会验证吗？

代码如下:

验证.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: ~

用户类型.php

namespace DEMO\DemoBundle\Form\Type\User;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\CallbackValidator;
use Symfony\Component\Form\FormBuilder;
use Symfony\Component\Form\FormError;

use DEMO\DemoBundle\Form\Type\User\ProfileType;

class UserType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder->add('username');
        $builder->add('email');
        $builder->add('profile', new ProfileType());
    }

    public function getDefaultOptions(array $options)
    {
        return array(
            'data_class' => 'DEMO\DemoBundle\Entity\User\User',
            'validation_groups' => array('profile')
        );
    }

    public function getName()
    {
        return 'user';
    }
}

ProfileType.php

namespace DEMO\DemoBundle\Form\Type\User;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\CallbackValidator;
use Symfony\Component\Form\FormBuilder;
use Symfony\Component\Form\FormError;

class ProfileType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder->add('name');
        $builder->add('companyName', null, array('label' => 'Company Name'));
        $builder->add('address1', null, array('label' => 'Address 1'));
        $builder->add('address2', null, array('label' => 'Address 2'));
        $builder->add('city');
        $builder->add('county');
        $builder->add('postcode');
        $builder->add('telephone');
    }

    public function getDefaultOptions(array $options)
    {
        return array(
            'data_class' => 'DEMO\DemoBundle\Entity\User\Profile',
        );
    }

    public function getName()
    {
        return 'profile';
    }
}

Controller

$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()));

最佳答案

我花了很长时间搜索，发现它正在将 'cascade_validation' => true 添加到修复它的父类型类中的 setDefaults() 数组中(如已经在线程中提到)。这会导致在表单中显示的子类型中触发实体约束验证。例如

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

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

$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 UniqueEntity 验证。
