symfony – FOSUser Bundle ..重写表单类型时无法加载类型“X”错误

我以为我非常仔细地遵循了文档,但由于某种原因,我收到此错误消息..

无法加载“sam_user_registration”类型

// src / Sam / Bundle / UserBundle / Entity / User.PHP

namespace Sam\Bundle\UserBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Entity\User as BaseUser;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * @ORM\Entity
 * @ORM\Table(name="sam_user")
 */
class User extends BaseUser
{
/**
 * @var string $id
 *
 * @ORM\Id
 * @ORM\Column(name="id",type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**
 * Get id
 *
 * @return string $id
 */
public function getId()
{
    return $this->id;
}

/**
 * @ORM\Column(type="string",length=255)
 *
 * @Assert\NotBlank(message="Please enter your name.",groups={"Registration","Profile"})
 * @Assert\MinLength(limit="3",message="The name is too short.","Profile"})
 * @Assert\MaxLength(limit="255",message="The name is too long.","Profile"})
 */
protected $name;

// src / Sam / Bundle / UserBundle / Form / Type / RegistrationFormType.PHP

<?PHP

namespace Sam\Bundle\UserBundle\Form\Type;

use Symfony\Component\Form\FormBuilderInterface;
use FOS\UserBundle\Form\Type\RegistrationFormType as BaseType;

class RegistrationFormType extends BaseType
{
public function buildForm(FormBuilderInterface $builder,array $options)
{
    parent::buildForm($builder,$options);

    // add your custom field
    $builder->add('name');
}

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

registration:

            type:               sam_user_registration

解决方法

首先,您的用户类缺少其构造函数.由于您继承了BaseUser,因此您也必须调用父构造函数.所以…

public function __construct()
{
    parent::__construct();

    //your code

}

其次,您不需要覆盖表单类型.由于您已将名称字段添加到您的实体,因此它将自动通过您的表单提供

{{ form_widget(myForm.name)} }

-> FosUserBundle Doc

但是,您确定在config.yml中导入了services.xml吗？为什么要混合使用xml和yml？坚持一个.

imports:
    - { resource: @SamBundleUserBundle/Resources/config/services.yml }
