【问题描述】：

我对 Express 和 Sequelize 使用 passport.js 有以下身份验证策略：

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);
        })
    );

};

问题是当我执行代码时，它无法插入到数据库中，并出现以下错误：

Executing (fa4929e4-6b35-40ce-9e02-daf80af507e1): START TRANSACTION;

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出错，一切正常。但是如果它开始创建一个用户，它就会出错，并且网页会停止。

更新：如果我只用 .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;

更新：删除.spread：

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;

【问题讨论】：

如果将 findOrCreate 替换为 find 会发生什么？由于您稍后创建用户，因此无需使用它。
删除spread:findOne({email: email}).then(function(user){ ... })
抱歉什么意思？
spread 期望值数组或承诺。但是findOne/find 返回单个值。所以用User.findOne({email: email}).then(function(user){ ... })替换User.findOne().spread()

【解决方案1】：

sequelize 模型不是构造函数（即不能调用new）。

http://docs.sequelizejs.com/en/latest/api/model/

将其用作工厂，通过调用 build（它返回一个新的、未保存的实例）或调用 create（它返回一个使用已保存实例解析的 Promise）来使用
