ExpressJS / Mongodb POST请求并丢失用户数据

Question

我有一个NodeJS应用程序，我正在尝试向我的用户个人资料页面添加一个'请求票证'功能。用户提交了一个在mongodb中创建新票证的请求，但是当我提交请求并尝试重新加载个人资料页面时，我丢失了用户数据。 （即未定义user.username）。

//User Open Ticket post
router.post('/openTicket', function(req,res,){
        var userDescription = req.body.userDescription
        var requestDevice     = req.body.requestDevice;
        var phonenumber = req.body.phonenumber;


        req.checkBody('requestDevice', 'Device is required').notEmpty();
        req.checkBody('userDescription', 'description is required').notEmpty();



        var errors = req.validationErrors();

    if(errors){
            console.log('Request has errors...');
            res.render('profile', {
                errors: errors,
                requestDevice: requestDevice,
                userDescription: userDescription,
            });
    } else {
            var phonenumber = phonenumber;

            var newTicket = {
                id: Math.random().toString(36).substring(2),
                requestDevice: requestDevice,
                userDescription: userDescription,
                openDate: new Date(),
                closeDate: "",
                techComment: "",
                status : "open",
            }

            db.users.update( {phonenumber: phonenumber }, {$set: {"tickets":  [newTicket]  } }, false, function(err, doc) {
                if(err){
                        res.send(err);
                    } else {
                        console.log('ticket Added...');
                        res.render('profile');

                    }
            });


        }
});

和我的控制台

[呈现个人资料页面时，您应该传递用户数据，res.render（'profile'，{用户：doc}）这样。
