使用Symfony official documentation, 我正在清理一些代码,并想替换Symfony中的Doctrine事件监听器(正在运行):
namespace App\EventListener;
use App\Entity\Comment;
use Doctrine\ORM\Event\LifecycleEventArgs;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
class CommentAuthorAssignmentListener
{
private $tokenStorage;
public function __construct(TokenStorageInterface $tokenStorage)
{
$this->tokenStorage = $tokenStorage;
}
public function prePersist(Comment $comment, LifecycleEventArgs $event)
{
dump($comment, $event); exit;
$comment->setAuthor($this->tokenStorage->getToken()->getUser());
}
}
services:
App\EventListener\CommentAuthorAssignmentListener:
autowire: true
tags:
- { name: doctrine.event_listener, event: prePersist }
使用更具体的Entity侦听器(没有错误,但根本没有触发):
namespace App\EventListener;
use App\Entity\Comment;
use Doctrine\ORM\Event\LifecycleEventArgs;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
class CommentAuthorAssignmentListener
{
private $tokenStorage;
public function __construct(TokenStorageInterface $tokenStorage)
{
$this->tokenStorage = $tokenStorage;
}
public function prePersist(Comment $comment, LifecycleEventArgs $event)
{
$comment->setAuthor($this->tokenStorage->getToken()->getUser());
}
}
services:
App\EventListener\CommentAuthorAssignmentListener:
autowire: true
tags:
- { name: doctrine.entity_listener , entity: 'App\Entity\Comment', event: prePersist }
一些注意事项:
cache:clear
答案 0 :(得分:1)
您好像打错了字
# these are the options required to define the entity listener
name: 'doctrine.orm.entity_listener'
event: 'postUpdate'
entity: 'App\Entity\User'
注意“ .orm”。在标签名称中,因此适合您的用例:
services:
App\EventListener\CommentAuthorAssignmentListener:
autowire: true
tags:
- { name: doctrine.orm.entity_listener , entity: 'App\Entity\Comment', event: prePersist }
