我正在制作用户注册表格，以便将记录插入mongodb。我在那里使用：
一切正常，除非使用构造函数 var newUser = new User（{...}）; 它返回错误对象不是函数
其余的工作正常。我在返回错误之前得到了日志，但我不知道如何解决这个问题。
users.js
var express = require('express');
var router = express.Router();
var User = require('../models/user');
/* GET users listing. */
router.get('/', function(req, res, next) {
res.send('respond with a resource');
});
router.get('/Registreren', function(req, res, next) {
res.render('Registration', { title: 'Registreren' });
});
router.get('/Aanmelden', function(req, res, next) {
res.render('Aanmelden', { title: 'Aanmelden' });
});
router.post('/Registreren', function(req, res, next){
// Get form value
console.log('Bericht in behandeling ...')
var username = req.body.username;
var email = req.body.email;
var password = req.body.password;
var password_confirm = req.body.password_confirm;
console.log('username: ' + username);
console.log('email: ' + email);
console.log('password: ' + password);
console.log('password_confirm: ' + password_confirm);
console.log('FIRST TEST: ' + JSON.stringify(req.file));
console.log('SECOND TEST: ' + req.file.profileimage);
console.log('THIRD TEST: ' + req.file.originalname);
// Check for image field
if (req.file || req.file.profileImage){
console.log('Uploading file....');
//File Info
var profileImageOrginalName = req.file.originalname;
var profileImageName = req.file.name;
var profileImageMimetype = req.file.mimetype;
var profileImagePath = req.file.path;
var profileImageExt = req.file.extension;
var profileImageSize = req.file.size;
} else{
console.log('profileImageFile not found....');
// Set default image
var profileImageName = 'noimage.png';
}
// Form validation
req.checkBody('username','Gebruikersnaam is verplicht').notEmpty();
req.checkBody('email','email is verplicht').notEmpty();
req.checkBody('email','email is niet geldig').isEmail();
req.checkBody('username','Gebruikersnaam is verplicht').notEmpty();
req.checkBody('password','Wachtwoord is verplicht').notEmpty();
req.checkBody('password_confirm','Wachtwoorden zijn niet `gelijk').equals(req.body.password);`
// Error handling
var errors = req.validationErrors();
console.log(errors);
if(errors){
console.log('Error handling....');
res.render('Registration',{
errors: errors,
email: email,
username: username,
password: password,
password_confirm: password_confirm
});
} else {
console.log('Make new User ....');
console.log('email: ' + email);
console.log('username: ' + username);
console.log('password: ' + password);
console.log('profileImageName: ' + profileImageOrginalName);
var newUser = new User({
email: email,
username: username,
password: password,
profileimage: profileImageOrginalName
});
console.log('---------------- START TEST----------------------------');
console.log('FIRST TEST: ' + JSON.stringify(newUser));
console.log('SECOND TEST: ' + newUser);
// Create User
User.createUser(newUser, function(err,user){
if(err) throw err;
});
// Succes message
req.flash('succes','Je bent succesvol aangemedld');
res.location('/');
res.redirect('/');
}
});
module.exports = router;

我已阅读以下帖子：
我已尝试构建更多日志记录，您可以在脚本中看到，以便我可以确定问题的来源。但我不知道如何解决这个问题。我希望你能帮助我。
