php - 尝试将字段添加到注册表单时无法加载类型 "app_user_registration"

Question

我正在使用 Doctrine 和 FOSBundle 2.0 在 Symfony3 中开发一个应用程序。

我一直在尝试在我的注册栏中添加两个字段 firstName 和 lastName。

I have found this tutorial on how do do precisely what I'm hoping ，不幸的是，在前几个步骤之后(在处理之前)我意识到我收到了这个错误:

Could not load type "app_user_registration"

我使用的代码是从网站上完全复制的，唯一的区别是我的类看起来像这样

<?php
// src/AppBundle/Entity/User.php

namespace AppBundle\Entity;

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

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

    /** @ORM\Column(type="integer") */
    protected $carma;

    /**
     * @ORM\Column(type="string", length=255)
     *
     * @Assert\NotBlank(message="Please enter your first name.", groups={"Registration", "Profile"})
     * @Assert\Length(
     *     min=3,
     *     max=255,
     *     minMessage="The name is too short.",
     *     maxMessage="The name is too long.",
     *     groups={"Registration", "Profile"}
     * )
     */
    protected $firstName;

    /**
     * @ORM\Column(type="string", length=255)
     *
     * @Assert\NotBlank(message="Please enter your first name.", groups={"Registration", "Profile"})
     * @Assert\Length(
     *     min=3,
     *     max=255,
     *     minMessage="The name is too short.",
     *     maxMessage="The name is too long.",
     *     groups={"Registration", "Profile"}
     * )
     */
    protected $lastName;

当有一个名为..."name"的变量时会发生同样的效果

我花了最后几个小时试图找出答案。这是我尝试过的:

• 使用2.0-master版教程
• The answer form here

其他一切都显示我的输出代码作为问题的答案。

谁能帮助一个可怜的人？

作为补充，这是我的其他文件:

//config.yml
/*...*/
fos_user:
    db_driver: orm
    firewall_name: main
    user_class: AppBundle\Entity\User
    registration:
        form:
            type: AppBundle\Form\RegistrationType

---

//services.yml
services:
    app.form.registration:
        class: AppBundle\Form\RegistrationType
        tags:
            - { name: form.type, alias: app_user_registration }

//RegistraionType.php
<?php
// src/AppBundle/Form/RegistrationType.php

namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class RegistrationType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('firstName');
    }

    public function getParent()
    {
        return 'fos_user_registration';
    }

    public function getName()
    {
        return $this->getBlockPrefix();
    }

    public function getBlockPrefix()
    {
        return 'app_user_registration';
    }
}

你应该改用这个教程(2.0.master): http://symfony.com/doc/master/bundles/FOSUserBundle/overriding_forms.html

您正在使用教程“1.3.x 版本”。

对于 Symfony3，您必须进行以下更改:

class RegistrationType extends AbstractType{    public function buildForm(FormBuilderInterface $builder, array $options)    {        $builder->add('name');    }    public function getParent()    {        return 'FOS\UserBundle\Form\Type\RegistrationFormType';    }    public function getBlockPrefix()    {        return 'app_user_registration';    }}

services:    app.form.registration:        class: AppBundle\Form\RegistrationType        tags:            - { name: form.type, alias: app_user_registration }

fos_user:    # ...    registration:        form:            type: AppBundle\Form\RegistrationType
