Symfony2 + Doctrine2在我的數據庫中未更新

Question

我在symfony2中有一個api，在其中沒有添加和刪除項的問題，但是，更新不會引發任何錯誤，但是數據庫中的relevent行不會得到更新！

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;
}

我完全知道，在更新實體時，我不需要使用$ em-> persist（$ machine），但是刪除它似乎沒有任何區別。

真正磨合我的齒輪的部分是，當我進行探查器時，它按預期運行了所有查詢！

Answer 1

剛剛意識到我一直是個白痴，我的問題是狀態在我的實體中設置為布爾值字段，因此它正在更新，但始終將其設置為1！
