FOSUserBundle：Get EntityManager实例覆盖Form Handler [英] FOSUserBundle: Get EntityManager instance overriding Form Handler

问题描述

我从Symfony2开始，我试图覆盖FOSUserBundle的FOS\UserBundle\Form\Handler\RegistrationFormHandler。

我的代码是： / p>

 <？php 
 
命名空间Testing\CoreBundle\Form\Handler; 
 
使用FOS\UserBundle\Model\UserInterface; 
使用FOS\UserBundle\Form\Handler\RegistrationFormHandler作为BaseHandler; 
使用Testing\CoreBundle\Entity\User作为UserDetails; 
 
 class RegistrationFormHandler extends BaseHandler 
 {
 
 protected function onSuccess（UserInterface $ user，$ confirmation）
 {
 //我需要一个实体经理的实例，但我不知道在哪里得到它！ 
 $ em = $ this-> container-> get（'doctrine'） - > getEntityManager（）; 
 //或类似的东西：$ em = $ this-> getDoctrine（） - > getEntityManager 
 
 $ userDetails = new UserDetails; 
 $ em-> persist（$ userDetails）; 
 
 $ user-> setId（$ userDetails-> getId（））; 
 
 parent :: onSuccess（$ user，$ confirmation）; 
} 
} 
  

所以，关键是我需要一个Doctrine的实体经理，但我不知道在哪里/如何在这种情况下！

任何想法？

提前感谢！

解决方案

1. 您不应该使用 EntityManager 直接在大多数情况下。使用适当的管理员/提供商服务。

   
   
   

   如果FOSUserBundle服务实现 UserManagerInterface 是这样的经理。它可以通过服务容器中的 fos_user.user_manager 键来访问（这是 fos_user.user_manager.default ）。当然，注册表单处理程序使用该服务，可以通过 userManager 属性。




2. 您不应该将您的域模型（ia Doctrine的实体）视为数据库模型。这意味着您应该将对象分配给其他对象（而不是其ID）。

   
   
   

   原则能够处理实体中的嵌套对象（ UserDetails 和用户对象有直接关系）。最终你将必须用户实体，rel =nofollow>配置级联选项。




3. UserDetails 似乎是每个用户的强制依赖关系。因此，您应该覆盖 UserManagerInterface :: createUser（）而不是表单处理程序 - 您还没有处理用户的详细信息。

   
   

   1. 创建自己的 UserManagerInterface 实现：

        class MyUserManager extends \FOS\UserBundle\Entity\UserManager {
       / ** 
       * {@inheritdoc} 
       * / 
       public function createUser（）{
       $ user = parent :: createUser（）; 
       
       $ user-> setUserDetails（new UserDetails（））; 
       //一个适当的
      所需的一些可选代码//初始化User / UserDetails对象
       //可能需要访问其他对象
       //在实体内不可用
       
       return $ user; 
      } 
      } 
        

   
   

   2. 注册自己的经理作为一个serive里面DIC：

       < service id =my_project.user_managerclass =\MyProject\UserManagerparent =fos_user .user_manager.default/> 
        

   
   

   3. 配置FOSUserBundle以使用您自己的实现：

       ＃/app/config/config.yml 
       fos_user：
       ... 
      服务：
       user_manager：my_project。 user_manager 
        

   
   

I am starting with Symfony2 and I am trying to override FOS\UserBundle\Form\Handler\RegistrationFormHandler of FOSUserBundle.

My code is:

<?php

namespace Testing\CoreBundle\Form\Handler;

use FOS\UserBundle\Model\UserInterface;
use FOS\UserBundle\Form\Handler\RegistrationFormHandler as BaseHandler;
use Testing\CoreBundle\Entity\User as UserDetails;

class RegistrationFormHandler extends BaseHandler
{

    protected function onSuccess(UserInterface $user, $confirmation)
    {
        // I need an instance of Entity Manager but I don't know where get it!
        $em = $this->container->get('doctrine')->getEntityManager();
        // or something like: $em = $this->getDoctrine()->getEntityManager

        $userDetails = new UserDetails;
        $em->persist($userDetails);

        $user->setId($userDetails->getId());

        parent::onSuccess($user, $confirmation);
    }
}

So, the point is that I need an instance of Doctrine's Entity Manager but I don't know where/how get it in this case!

Any idea?

Thanks in advance!

解决方案

1. You should not use EntityManager directly in most of the cases. Use a proper manager/provider service instead.

   In case of FOSUserBundle service implementing UserManagerInterface is such a manager. It is accessible through fos_user.user_manager key in the service container (which is an allias to fos_user.user_manager.default). Of course registration form handler uses that service, it is accessible through userManager property.

2. You should not treat your domain-model (i.a. Doctrine's entities) as if it was exact representation of the database-model. This means, that you should assign objects to other objects (not their ids).

   Doctrine is capable of handling nested objects within your entities (UserDetails and User objects have a direct relationship). Eventually you will have to configure cascade options for User entity.

3. Finally, UserDetails seems to be a mandatory dependency for each User. Therefore you should override UserManagerInterface::createUser() not the form handler - you are not dealing with user's details there anyway.

   1. Create your own UserManagerInterface implementation:

      class MyUserManager extends \FOS\UserBundle\Entity\UserManager {
          /**
           * {@inheritdoc}
           */
          public function createUser() {
              $user = parent::createUser();
      
              $user->setUserDetails(new UserDetails());
              // some optional code required for a proper
              // initialization of User/UserDetails object
              // that might require access to other objects
              // not available inside the entity
      
              return $user;
          }
      }
      

   2. Register your own manager as a serive inside DIC:

      <service id="my_project.user_manager" class="\MyProject\UserManager" parent="fos_user.user_manager.default" />
      

   3. Configure FOSUserBundle to use your own implementation:

       # /app/config/config.yml
       fos_user:
           ...
           service:
               user_manager: my_project.user_manager
