Question

我在https://github.com/KnpLabs/DoctrineBehaviors/#softDeletable的实体中使用SoftDeletable特征它工作正常，但有时我想强行删除实体。我怎么能这样做？

当我使用<?php if(file_exists($_SERVER['DOCUMENT_ROOT'].'/'.$row['PandFoto3'])) { unlink($_SERVER['DOCUMENT_ROOT'].'/'.$row['PandFoto3']); } else { echo $row['PandFoto3']; }时，它会被软删除，但我需要将其从数据库中完全删除。

Answer 1

只需从EventManager移除订阅者，然后在remove() / flush()操作后重新添加订阅者。

// get the event-manager
$eventManager = $this->get('doctrine')->getEventManager();

// get the listener
$subscriber = $this->get('knp.doctrine_behaviors.softdeletable_subscriber');

// remove the the subscriber for all events
$eventManager->removeEventListener($subscriber->getSubscribedEvents(), $subscriber);

// remove the entity
$em->remove($entity);
$em->flush();

// add it back to the event-manager
$eventManager->addEventSubscriber($subscriber);

由于nifr的答案在当前版本的行为中不再起作用，我对问题有了更深入的了解并得到了解决方案：

$em = $this->getDoctrine()->getManager();

// initiate an array for the removed listeners
$originalEventListeners = array();

// cycle through all registered event listeners
foreach ($em->getEventManager()->getListeners() as $eventName => $listeners) {
    foreach ($listeners as $listener) {
        if ($listener instanceof Knp\DoctrineBehaviors\ORM\SoftDeletable\SoftDeletableSubscriber) {

            // store the event listener, that gets removed
            $originalEventListeners[$eventName] = $listener;

            // remove the SoftDeletableSubscriber event listener
            $em->getEventManager()->removeEventListener($eventName, $listener);
        }
    }
}

// remove the entity
$em->remove($entity);
$em->flush();

// re-add the removed listener back to the event-manager
foreach ($originalEventListeners as $eventName => $listener) {
    $em->getEventManager()->addEventListener($eventName, $listener);
}

我找到了简单的解决方案。实体将首先被软删除，但如果它已经被软删除，它将被删除，所以我的简单解决方案是：

$entity->setDeletedAt(new DateTime());
$entityManager->remove($entity);
$entityManager->flush();

当然你需要禁用＆＃39; softdelete＆＃39;首先过滤并删除它是一个sofdelete字段。
