好的，我按照Joel Verhagen的思路在 Codeigniter 中使用 Doctrine2 ，一切正常，但现在我遇到了一个神秘的问题。
销毁物品时，一切正常：
$delete = $this->doctrine->em->getRepository('Entities\Item')->findOneBy(array('slug' => $item));
$this->doctrine->em->remove($delete);
$this->doctrine->em->flush();
但是在 getRepository() 之后，更新项目会默默地失败：
$item = $this->doctrine->em->getRepository('Entities\Item')->findOneBy(array('id' => $id));
$item->setDescription(html_entity_decode($_POST['content']));
$this->doctrine->em->persist($item);
$this->doctrine->em->flush();
相同的控制器，这就是每个动作中的所有代码。我所有的其他控制器都很好，但这失败了，没有任何日志。拆分 getRepository 和 find 调用在 getRepository 之后立即终止。将 getRepository 移动到 __construct 会导致 update() 因查找而死。
想法？线索？似乎 SO 上的其他任何人最终要么走向不同的方向，要么从未解决过问题。
谢谢！
