Question

EasyAdminBundle使用FOSUserBundle用户操纵器来创建＆amp;管理用户。我想捕获创建用户时使用的密码来更新后缀数据库。创建用户时，dev profiler不会显示已侦听任何FOSUserBundle事件。唯一的EasyAdminBundle事件是easy_admin.post_initialize。 EasyAdminEvents班级显示

/** @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 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)
    {
        ...
    }

然而，这样做给了我这个Catch 22：

必须是。的实例 JavierEguiluz \ Bundle \ EasyAdminBundle \ Event \ EasyAdminEvents，实例给出“
的Symfony \ Component \ EventDispatcher \ GenericEvent

Answer 1

所以最简单的答案是改变类型提示，如：

    public function onPostInitialize(GenericEvent $event)
    {
        ...
    }

EasyAdminBundle事件POST_INITIALIZE是未定义的类常量
