我坚持用Symfony2创建用户注册表单。
我正在尝试在email
类的User
属性上定义唯一约束。
的Acme \的appbundle \实体\ user.php的
namespace Acme\APPBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
/**
* @ORM\Entity
* @ORM\Entity(repositoryClass="Acme\APPBundle\Entity\UserRepository")
* @ORM\Table("users")
* @UniqueEntity(
* fields={"email"},
* message="email already used"
* )
*/
class User implements UserInterface, \Serializable
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=255, unique=true)
* @Assert\NotBlank()
* @Assert\Email()
*/
protected $email;
[...]
}
的Acme \的appbundle \表格\型号\ UserType.php
namespace Acme\APPBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class UserType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('email', 'email');
$builder->add('password', 'repeated', array(
'first_name' => 'password',
'second_name' => 'confirm',
'type' => 'password',
));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Acme\APPBundle\Entity\User',
'cascade_validation' => true,
));
}
public function getName()
{
return 'user';
}
}
我在文档后面添加了约束,但我仍然得到一个例外:
An exception occured while executing 'INSERT INTO users ( ... )'
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry
看起来注释中定义的message
值被忽略,并且表单验证被绕过,因为它在尝试在数据库中插入行之前会失败。
你能告诉我我做错了什么吗?
编辑:
按照Matteo'Ingannatore'G。的建议,我注意到我的表单没有经过适当的验证。 我忘了提到我使用扩展用户表单的注册类。我按照Symfony Cookbook中解释的内容编写了我的代码。
因此我有:
的Acme \的appbundle \表格\模型\为registration.php
namespace Acme\APPBundle\Form\Model;
use Symfony\Component\Validator\Constraints as Assert;
use Acme\APPBundle\Entity\User;
class Registration
{
/**
* @Assert\Type(type="Acme\APPBundle\Entity\User")
*/
protected $user;
/**
* @Assert\NotBlank()
* @Assert\True()
*/
protected $termsAccepted;
public function setUser(User $user)
{
$this->user = $user;
}
public function getUser()
{
return $this->user;
}
public function getTermsAccepted()
{
return $this->termsAccepted;
}
public function setTermsAccepted($termsAccepted)
{
$this->termsAccepted = (Boolean) $termsAccepted;
}
}
的Acme \的appbundle \表格\型号\ RegistrationType.php
namespace Acme\APPBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
class RegistrationType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('user', new UserType());
$builder->add('terms', 'checkbox', array('property_path' => 'termsAccepted'));
}
public function getName()
{
return 'registration';
}
}
的Acme \的appbundle \控制器\ AccountController.php
namespace Acme\APPBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use Acme\AccountBundle\Form\Type\RegistrationType;
use Acme\AccountBundle\Form\Model\Registration;
class AccountController extends Controller
{
public function registerAction()
{
$form = $this->createForm(new RegistrationType(), new Registration());
return $this->render('AcmeAPPBundle:Account:register.html.twig', array('form' => $form->createView()));
}
public function createAction()
{
$em = $this->getDoctrine()->getEntityManager();
$form = $this->createForm(new RegistrationType(), new Registration());
$form->handleRequest($this->getRequest());
if ($form->isValid()) { // FIXME !!
$registration = $form->getData();
$em->persist($registration->getUser());
$em->flush();
return $this->redirect($this->generateUrl('home'));
}
return $this->render('AcmeAPPBundle:Account:register.html.twig', array('form' => $form->createView()));
}
}
我想我得到的错误可能是由于Registration
表单已经过验证,但其中的User
表单未提交验证。我错了吗 ?
我怎样才能简单地改变这种行为?我看到有一个cascade_validation
选项,但在这里似乎没用。
我认为Symfony Cookbook提供创建用户提供者和创建注册表单的指南很奇怪,但没有解释如何让这些工作顺利进行。
