我使用passport.js对Express和Sequelize进行了以下身份验证策略：
var LocalStrategy = require('passport-local').Strategy;
var User = require('../../models').User;
module.exports = function (passport) {
passport.use('register', new LocalStrategy({
passReqToCallback: true,
usernameField: 'email'
}, function (req, email, password, done) {
//var findOrCreateUser = function () {
// find a user in Mongo with provided username
User.findOrCreate({where: {email: email}}).spread(
function (user, created) {
// In case of any error, return using the done method
//if (err) {
// console.log('Error in SignUp: ' + err);
// return done(err);
//}
if (email !== req.param('email-confirm')) {
console.log('Registration: Email address do not match');
return done(null, false, {message: 'Email addresses do not match'});
}
// already exists
if (user) {
console.log('User ' + email + ' is already registered.');
return done(null, false, {'message': 'The email ' + email + ' is already registered.'});
} else {
// if there is no user with that email
// create the user
var newUser = new User();
// set the user's local credentials
newUser.email = email;
newUser.password = password;
// save the user
newUser.save(function (err) {
if (err) {
console.log('Error in Saving user: ' + err);
throw err;
}
console.log('New user registration', newUser);
return done(null, newUser);
});
}
});
//};
//// Delay the execution of findOrCreateUser and execute the method
//// in the next tick of the event loop
//process.nextTick(findOrCreateUser);
})
);
};
问题在于，当我执行代码时，它无法插入到db中，并出现以下错误：

我知道这是在用户创建期间，因为如果我使用相同的电子邮件地址来解决错误，那么一切都有效。但是如果它开始创建一个用户就会出错，并且网页会停止。
更新：如果我只使用.find运行它：
Executing (default): SELECT "id", "email", "password", "lastLogin", "createdAt", "updatedAt", "deletedAt" FROM "Users" AS "User" WHERE ("User"."deletedAt" IS NULL AND "User"."email" = 'user@email.com') LIMIT 1;

答案 0 :(得分：1)
sequelize模型不是构造函数（即你不能调用new）。
http://docs.sequelizejs.com/en/latest/api/model/
将其用作工厂，方法是调用build，返回一个未保存的新实例，或调用create，返回一个使用已保存实例解析的承诺
