我在symfony2中有一个api，其中添加和删除项目没有问题，但是，更新不会给我带来任何错误，但是我的数据库中的相关行没有得到更新！
我的控制器方法：
/*
* @Route("/complete/uid/{storeUid}",
* name = "media_complete"
* )
*
* @Method({"GET"})
*
* @param String $storeUid - the uid for the store that has completed downloading
*
* @return Response
*/
public function downloadCompleteAction($storeUid)
{
$response = $this->getNewJsonResponse();
$em = $this->getDoctrine()->getManager();
$repo = $em->getRepository("SimplySmartUHDProBundle:Machine");
try {
//get the machine from the db
$machine = $repo->findOneBy(array(
"uid" => $storeUid
));
//set it as download completed
$machine->setStatus(Machine::STATUS_DOWNLOAD_COMPLETE);
$em->persist($machine);
$em->flush();
$response->setStatusCode(200);
} catch (\Exception $e) {
//if there is an error, catch the exception set the status to 500 and return json with the exception error
$error = array("message" => $e->getMessage());
$response->setContent(json_encode($error));
$response->setStatusCode(500);
}
return $response;
}

我完全清楚在更新实体时我不需要使用$ em-＆gt; persist（$ machine），但是删除它似乎没有任何区别。
真正磨练我的齿轮的部分是，当我进入探查器时，看起来它按预期运行所有查询！
答案 0 :(得分：0)
刚才意识到我是一个完全白痴，我的问题是我的实体中状态被设置为布尔字段，所以它正在更新，但始终将其设置为1！
