Question

我尝试注册用户。当试图将关于他的信息保存到数据库中时（使用PostgreSQL）我得到的错误不是函数。

如果我需要添加更多代码，请不要犹豫。

如果您对node.js和postgres的用户注册有一个很好的教程，请将它链接到我。

感谢您的帮助：D

完整错误：

Passport.js

var passport = require('passport')
    , LocalStrategy = require('passport-local').Strategy
    , db = require('../models')

// Serialize Sessions
passport.serializeUser(function(user, done){
    done(null, user);
});

//Deserialize Sessions
passport.deserializeUser(function(user, done){
    db.User.find({where: {id: user.id}}).success(function(user){
        done(null, user);
    }).error(function(err){
        done(err, null)
    });
});

// For Authentication Purposes
passport.use(new LocalStrategy(
    function(username, password, done){
        db.User.find({where: {username: username}}).success(function(user){
            passwd = user ? user.password : ''
            isMatch = db.User.validPassword(password, passwd, done, user)
        });
    }
));

user.js的

var bcrypt = require('bcrypt-nodejs')

module.exports = function (sequelize, DataTypes) {
    var User = sequelize.define('User', {
            name: {type: DataTypes.STRING},
            email: {type: DataTypes.STRING, unique: true},
            username: {type: DataTypes.STRING, unique: true},
            password: {type: DataTypes.STRING}
        }
        , {
            instanceMethods: {
                generateHash: function (password, done) {
                    bcrypt.genSalt(SALT_WORK_FACTOR, function (err, salt) {
                        bcrypt.hash(password, salt, null, done);
                    });
                },
                validPassword: function (password, next) {
                    bcrypt.compare(password, this.password, next)
                }
            }
        })
    User.beforeCreate(function (user, done) {
        user.generateHash(user.password, function (err, encrypted) {
            if (err) return done(err);
            user.password = encrypted;
            done(null, user);
        })
    })
    return User;

User.beforeCreate有3个参数模型，选项和回调函数，这是在你的情况下完成所以写这个：

User.beforeCreate(function (user, options, done)

如何使用node.js在postgres DB中保存用户 - TypeError：done不是函数
