从 Symfony2 控制器中删除 Doctrine 生命周期事件 [英] Remove Doctrine life cycle event from within a Symfony2 controller

问题描述

我希望删除 Doctrine Extensions 生命周期来自控制器内的事件监听器.

我需要删除更新事件的侦听器，因为我需要一次更新树中的所有节点.库不支持的东西，但可以通过直接设置正确的左、右、水平等来实现......

I need to remove the listener for update events because I need to update all nodes in the tree at once. Something that is not supported by the library, but is possible by directly setting the correct left, right, level etc...

是否可以从控制器中删除生命周期?这种情况有什么可能的解决方案.

Is it possible to remove a life cycle even from within a controller? What is a possible solution for this situation.

我认为这样的事情可能会奏效，但它没有

I thought something like this might work, but it did not

$evm = $em->getEventManager();

$listener = new GedmoTreeTreeListener();
$evm->removeEventListener( array( 'postUpdate' ), $listener );

推荐答案

可以，但是使用了不同的事件:

yes it will work, but there are different events used:

$listenerInst = null;
$em; /* entity manager */
foreach ($em->getEventManager()->getListeners() as $event => $listeners) {
    foreach ($listeners as $hash => $listener) {
        if ($listener instanceof WantedListenerClass) {
            $listenerInst = $listener;
            break 2;
        }
    }
}
$listenerInst || die('Listener is not registered in the event manager');
// then you can remove events you like:
$evm = $em->getEventManager();
$evm->removeEventListener(array('onFlush'), $listenerInst);
