Symfony2 / Doctrine - postFlush

问题描述

如果你看到我以前的问题，这是一种与之相关的一个新问题。所以我有一个实体，我有一个听众连接到这个。在我的createAction中，我创建了我的对象，然后将其刷新到我的数据库。在我的监听器中，我设置了一个postFlush函数

  public function postFlush（PostFlushEventArgs $ args）
 {
 $ em = $ args-> getEntityManager（）; 
 
 foreach（$ em-> getUnitOfWork（） - > getScheduledEntityDeletions（）as $ entity）{
 if（$ entity instanceof AvailabilityAlert）{
 var_dump（TEST ）; 
 $ this-> api_service-> addFlightsAction（$ entity）; 
} 
} 
} 
  

我正在努力做什么在这个函数中获取刚被刷新的实体。我已经尝试过getUnitsOfWork的所有不同的动作。 getScheduledEntityDeletions但是没有一个我可以进入var_dump发生的地方。

如何在这个postFlush函数中获取被刷新的实体？

解决方案

根据Doctrine2文档：您不能调用 PostFlush 事件。但是您可以拆分逻辑：使用 OnFlush 事件来获取这些实体，然后将其传递给 PostFlush 如果刷新成功。

If you saw my previous question, this is kind of linked to it but a new question. So I have an Entity and I have a listener linked up to this. In my createAction I create my Object and then persist-flush it to my database. In my listener, I have set up a postFlush function

public function postFlush(PostFlushEventArgs $args)
{
    $em = $args->getEntityManager();

    foreach ($em->getUnitOfWork()->getScheduledEntityDeletions() as $entity) {
        if ($entity instanceof AvailabilityAlert) {
            var_dump("TEST");
            $this->api_service->addFlightsAction($entity);
        }
    }
}

What I am trying to do in this function is get the entity that was just flushed. I have tried all the different actions of getUnitsOfWork e.g. getScheduledEntityDeletions but for none of them I can get into where the var_dump occurs.

How would I go about getting the flushed entity within this postFlush function?

解决方案

According to Doctrine2 documentation here : http://doctrine-orm.readthedocs.org/en/latest/reference/events.html you can't call the flushed entities on PostFlush event.

However you can split your logic : use the OnFlush event to get these entities and then pass it to the PostFlush if the flush succeeded.
