FOSUserBundle给用户添加一个组不会做任何事情

Question

我使用FOSuser与SonataUserBundle，我试图添加一个用户到客户组每次有人注册，但它不起作用。我没有得到任何错误，但我也没有添加组…我尝试了两种方法:

1)我重写了registrationController，并使confirmAction像这样保存新组:

    /**
     * Tell the user his account is now confirmed
     */
    public function confirmedAction()
    {
     $repository = $em->getRepository('ApplicationSonataUserBundle:Group');
        $group = $repository->findOneByName('Clients');
        $em = $this->getDoctrine()->getEntityManager();
        $user = $this->getUser();
        $user->addGroup($group);
        $this->em->flush();
        $userManager = $this->get('fos_user.user_manager');
        $userManager->updateUser($user);
    }
}

2)创建一个eventListener并在那里进行分组:

<?php
namespace ApplicationSonataUserBundleEventListener;
use FOSUserBundleFOSUserEvents;
use FOSUserBundleEventFormEvent;
use SymfonyComponentEventDispatcherEventSubscriberInterface;
use DoctrineORMEntityManager;
/**
 * Listener responsible to change the redirection at the end of the password resetting
 */
class GrouppingListener implements EventSubscriberInterface
{
    protected $em;
    protected $user;
    public function __construct(EntityManager $em)
    {
        $this->em = $em;
    }
    /**
     * {@inheritDoc}
     */
    public static function getSubscribedEvents()
    {
        return array(
            FOSUserEvents::REGISTRATION_SUCCESS => 'onRegistrationSuccess',
        );
    }
    public function onRegistrationSuccess(FormEvent $event)
    {
        $this->user = $event->getForm()->getData();
        $entity = $this->em->getRepository('ApplicationSonataUserBundle:Group')->findOneByName('Clients'); // You could do that by Id, too
        $this->user->addGroup($entity);
        $this->em->flush();
    }
}

我的组实体被这样扩展:

<?php
/**
 * This file is part of the <name> project.
 *
 * (c) <yourname> <youremail>
 *
 * For the full copyright and license information, please view the LICENSE
 * file that was distributed with this source code.
 */
namespace ApplicationSonataUserBundleEntity;
use SonataUserBundleEntityBaseGroup as BaseGroup;
/**
 * This file has been generated by the Sonata EasyExtends bundle ( http://sonata-project.org/bundles/easy-extends )
 *
 * References :
 *   working with object : http://www.doctrine-project.org/projects/orm/2.0/docs/reference/working-with-objects/en
 *
 * @author <yourname> <youremail>
 */
class Group extends BaseGroup
{
    /**
     * @var integer $id
     */
    protected $id;
    /**
     * Get id
     *
     * @return integer $id
     */
    public function getId()
    {
        return $this->id;
    }
}

这些选项都不起作用…我这样做是基于其他stackoverflow的答案…为什么行不通呢?

Answer 1

您在两个案例中都缺少persist。为了使实体变得可管理，它首先需要被持久化。

$user->addGroup($group);
$this->em->flush();

在你的控制器动作中将此改为:

$user->addGroup($group);
$this->em->persist($user);
$this->em->flush();

教条手册中的一段:

实体可以通过传递给EntityManager#persist($entity)方法来持久化。通过在某些实体上应用持久化操作，该实体变成MANAGED，这意味着它的持久化从现在开始由EntityManager管理。因此，当调用EntityManager#flush()时，这样一个实体的持久状态随后将与数据库正确同步。
