EasyAdminBundle 使用 FOSUserBundle 用户操纵器来创建和管理用户。我想捕获创建用户以更新后缀数据库时使用的密码。创建用户时,开发分析器不会显示已侦听任何 FOSUserBundle 事件。唯一的 EasyAdminBundle 事件是easy_admin.post_initialize
. 班级EasyAdminEvents
展示
/** @Event("Symfony\Component\EventDispatcher\GenericEvent") */
const POST_INITIALIZE = 'easy_admin.post_initialize';
但是一个事件监听器:
use Symfony\Component\EventDispatcher\GenericEvent;
...
public static function getSubscribedEvents()
{
return array(
GenericEvent::POST_INITIALIZE => 'onPostInitialize',
);
}
抛出:
致命错误:未捕获的 Symfony\Component\Debug\Exception\FatalThrowableError:未定义的类常量 'POST_INITIALIZE' ...
我认为答案是使用JavierEguiluz\Bundle\EasyAdminBundle\Event\EasyAdminEvents
事件而不是 Symfony GenericEvent
。如在
use JavierEguiluz\Bundle\EasyAdminBundle\Event\EasyAdminEvents;
...
public static function getSubscribedEvents()
{
return array(
EasyAdminEvents::POST_INITIALIZE => 'onPostInitialize',
);
}
...
//error occurs on the following line:
public function onPostInitialize(EasyAdminEvents $event)
{
...
}
但是,这样做给了我这个 Catch 22:
必须是 JavierEguiluz\Bundle\EasyAdminBundle\Event\EasyAdminEvents 的实例,给定 Symfony\Component\EventDispatcher\GenericEvent 的实例”
