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

我正在寻找一个原则扩展程序生命周期事件侦听器。

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。图书馆不支持的内容，但可以通过直接设置正确的左，右，等级等来实现。

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...

是否可以删除生命周期甚至从控制器内部？对于这种情况，什么是可能的解决方案。

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

我以为这样的事情可能会起作用，但没有

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

$evm = $em->getEventManager();

$listener = new \Gedmo\Tree\TreeListener();
$evm->removeEventListener( array( 'postUpdate' ), $listener );

推荐答案

是的，它会工作，但有不同的事件：

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);
