以下是我的数据库结构：

以下是我的代码：

我也得到了同样的错误我的路线，如果你有任何帮助，请让知道，这里是代码

 router.post('/UpdateStatus', function(req, res) { if(sess){ var id = req.body.id; var type = req.body.type; var status = req.body.status; if(type == "licence"){ var up = TableUser.child(id).update({ licenceStatus:status }); if(up){ //res.redirect('/drivers'); res.render('d'); }else{ console.log("error updating code"); } } }else{ res.redirect('/'); } });
