Symfony 3.2 FOSMessageBundle '.../new'（即撰写新消息）无论我做什么都会抛出错误

Question

我没有使用 FOSUserBundle（已经有自定义用户/安全代码）。我一直在关注文档here。

在对 Symfony 和 FOSMessageBundle 文件进行大量搜索和挖掘之后，我开始相信这个问题与新的 NewThreadMessageFormFactory 类有关。它只有一种方法。如果我保持原样

    public function create()
    {
        return $this->formFactory->createNamed(
          $this->formName, 
          $this->formType, 
          $this->createModelInstance());
    }

我收到此错误Expected argument of type "string", "AppBundle\Service\NewThreadMessageFormType" given。另一方面，如果我执行以下操作，

public function create()
{
    return $this->formFactory->createNamed(
      $this->formName,
      'AppBundle\Service\NewThreadMessageFormType', 
      $this->createModelInstance());
}

我知道了Could not load type "FOS\UserBundle\Form\Type\UsernameFormType。当然，它甚至不存在，因为 FOSUserBundle 甚至没有安装。

我已经为此花费了十几个小时。我在这个过程中学到了很多东西，但我仍然无法让这该死的东西发挥作用......

还有我目前的配置

//config.yml
fos_message:
    db_driver: orm
    thread_class: AppBundle\Entity\Thread
    message_class: AppBundle\Entity\Message
    new_thread_form:
        type: app.new_thread_form_type
        factory: app.new_thread_form_factory

还有……

  //services.yml
  fos_user.user_to_username_transformer:
      alias: app.user_to_username_transformer

  app.user_to_username_transformer:
      class: AppBundle\Form\DataTransformer\UserToUsernameTransformer
      arguments:
          type: "service"
          id: "doctrine"

  app.new_thread_form_type:
      class: AppBundle\Service\NewThreadMessageFormType
      arguments: ['@app.user_to_username_transformer']
      tags:
          - {name: form.type}

  app.new_thread_form_factory:
      class: AppBundle\Service\NewThreadMessageFormFactory
      arguments: [
          '@form.factory',
          '@fos_message.new_thread_form.type',
          '%fos_message.new_thread_form.name%',
          '%fos_message.new_thread_form.model%'
          ]

Answer 1

如果您不使用 FOSUSerBundle，则需要执行以下操作：

1. 按照指南Using other UserBundles 创建 UserToUsernameTransformer 类

2. 在 config.yml 中：

   fos_message:
       db_driver: orm
       thread_class: AppBundle\Entity\Thread
       message_class: AppBundle\Entity\Message
       new_thread_form:
           type: AppBundle\Form\Type\NewThreadMessageFormType
   

3. 注册服务：

   app.user_to_username_transformer:
       class: AppBundle\Form\DataTransformer\UserToUsernameTransformer
       arguments: ['@doctrine']
   fos_user.user_to_username_transformer:
       alias: app.user_to_username_transformer
   app.form.type.username:
       class: AppBundle\Form\Type\UsernameFormType
       arguments: ['@app.user_to_username_transformer']
       tags:
           - { name: form.type }
   

4. 创建一个 NewThreadMessageFormType 表单类型类来覆盖默认的。

   class NewThreadMessageFormType extends AbstractType
   {
       public function buildForm(FormBuilderInterface $builder, array $options)
       {
           $builder
               ->add('recipient', UsernameFormType::class, array(
                   'label' => 'recipient',
                   'translation_domain' => 'FOSMessageBundle',
               ))
           ->add('subject', TextType::class, array(
               'label' => 'subject',
               'translation_domain' => 'FOSMessageBundle',
           ))
           ->add('body', TextareaType::class, array(
               'label' => 'body',
               'translation_domain' => 'FOSMessageBundle',
           ));
       }
   
       public function configureOptions(OptionsResolver $resolver)
       {
           $resolver->setDefaults(array(
               'intention' => 'message',
           ));
       }
   
       /**
        * {@inheritdoc}
        */
       public function getBlockPrefix()
       {
           return 'new_thread_message';
       }
   }
   

5. 创建一个 UsernameFormType 表单类型类来处理用户名的转换和显示。

   class UsernameFormType extends AbstractType
   {
       /**
        * @var UserToUsernameTransformer
        */
       protected $usernameTransformer;
   
       /**
        * Constructor.
        *
        * @param UserToUsernameTransformer $usernameTransformer
        */
       public function __construct(UserToUsernameTransformer $usernameTransformer)
       {
           $this->usernameTransformer = $usernameTransformer;
       }
   
       /**
        * {@inheritdoc}
        */
       public function buildForm(FormBuilderInterface $builder, array $options)
       {
           $builder->addModelTransformer($this->usernameTransformer);
       }
   
       /**
        * {@inheritdoc}
        */
       public function getParent()
       {
           return TextType::class;
       }
   
       /**
        * {@inheritdoc}
        */
       public function getBlockPrefix()
       {
           return 'toolsets_username_type';
       }
   }
   

这应该可以正常工作。
