Javascript NodeJS不'；我不喜欢护照&x2B；续集登录

我对nodejs快发疯了。我正在尝试使用Passport Local和Sequelize库实现一个由NodeJS支持的简单用户管理webapp的后端。现在我刚刚设计了用户模型。我的主要问题是注册过程给了我一个错误：看起来我正在处理一个未定义的对象。有人能帮我弄清楚发生了什么事吗

这是我的代码（与我在互联网上找到的一些解决方案合并在一起——根据墨菲定律，显然什么都不起作用）

如果代码不好，请Javascript程序员原谅我。我的理由是，这是我第一次尝试使用Javascript编程，我必须为一个项目这样做，最后（借口），但并非最不重要的是，我是在C和微芯片的环境中长大的

错误：

TypeError:无法读取未定义的属性“findOne” 在策略中进行验证（/home/me/Documents/cerbero/config/passport.js:21:17）

编辑 我忘了护照策略。 passport.js

var bCrypt = require('bcrypt-nodejs');


module.exports = function(passport, user) {

    var User = user;
    var LocalStrategy = require('passport-local').Strategy;
    console.log('debug: sono nella routine');


    passport.use('local-signup', new LocalStrategy(

        {
            usernameField: 'email',
            passwordField: 'password',
            passReqToCallback: true
        },
        function(req, email, password, done) {
          

            User.findOne({
                where: {
                    email: email
                }
            }).then(function(user) {
                if (user) {
                  return done(null, false, {message: req.flash('email already taken')});
                  console.log('mail already taken');
                }
                else {
                    var pass = generateHash(password);

                    var data =

                        {
                            email: email,
                            password: pass,
                            username: req.body.username,
                            public_key: '0',
                            last_login: null

                        };

                    User.create(data).then(function(newUser, created) {

                        if (!newUser) {

                            return done(null, false);

                        }

                        if (newUser) {

                            return done(null, newUser, {message: req.flash('tappost')});

                        }

                        next();

                    });

                }

            });

        }

    ));

    passport.deserializeUser(function(id, done) {

        User.findById(id).then(function(user) {

            if (user) {

                done(null, user.get());

            } else {

                done(user.errors, null);

            }

        });

    });


    passport.serializeUser(function(user,done) {
      done(null, user.id);
    });

var generateHash = function(password) {
                return bCrypt.hashSync(password, bCrypt.genSaltSync(8), null);
              };

问题解决了。 “Just”更改了如何引用passport.js中的模型，如下所示

var User = user;

不得不重写为

var User = db.user;

这里是最终的passport策略文件

const db = require('./../models/');
var bCrypt = require('bcrypt-nodejs');


module.exports = function(passport) {

    var User = db.user;
    var LocalStrategy = require('passport-local').Strategy;

    passport.use('local-signup', new LocalStrategy(

        {
            usernameField: 'email',
            passwordField: 'password',
            passReqToCallback: true
        },
        function(req, email, password, done) {
          var generateHash = function(password) {
            return bCrypt.hashSync(password, bCrypt.genSaltSync(8), null);
          };

            User.findOne({
                where: {
                    email: email
                }
            }).then(function(user) {
                if (user) {
                  return done(null, false, {message: req.flash('email already taken')});
                  console.log('mail already taken');
                }
                else {
                    var pass = generateHash(password);

                    var data =

                        {
                            email: email,
                            password: pass,
                            username: req.body.username,
                            public_key: '0',
                            last_login: null

                        };

                    User.create(data).then(function(newUser, created) {

                        if (!newUser) {

                            return done(null, false);

                        }

                        if (newUser) {

                            return done(null, newUser, {message: req.flash('tappost')});

                        }

                    });

                }

            }).catch(function(err) {
              console.log(err);
            });

        }

    ));


    passport.serializeUser(function(user, done) {
            done(null, user.id);
        });

        passport.deserializeUser(function(id, done) {
            User.findById(id).then(function(user){
                done(null, user);
            }).catch(function(e){
                done(e, false);
            });
        });

错误来自您的passport.js文件，但这是您没有包含供我们查看的文件！你说得对。我编辑了这个问题。现在你可以找到代码了。嗨，我想做passportJS登录和注册功能。你能和我分享一些关于这方面的教程或博客吗？
