mongoose Schema为续集模型

标签: mysql node.js mongodb mongoose sequelize.js

我用mongodb制作了一个应用程序(mongoose作为ODM),但现在想使用mysql(工作义务)所以我拿了Sequelize模块,但我真的不明白如何将我的userSchema转换为用户模型及其所有méthodes (我正在使用passportJs进行身份验证,所以我有一些方法可以使用例如setpassword ...)

这里我的userSchema(mongoose)完美无缺。

var mongoose = require('mongoose');
var crypto = require('crypto');
var jwt = require('jsonwebtoken');
var validator = require('node-mongoose-validator');
var Schema = mongoose.Schema;

var userSchema = new Schema({
    name: {
      type: String,
      maxlength: 50},
    mail: {
      type: String,
      required: true,
      maxlength: 50,
      index: {
        unique: true
      }
    },
    hash: String,
    salt: String,
    {
    collection: "user"
    }
);

userSchema.methods.setPassword = function(password) {
  this.salt = crypto.randomBytes(16).toString('hex');
  this.hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
};

userSchema.methods.validPassword = function(password) {
  var hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
  return this.hash === hash;
};

userSchema.methods.generateJwt = function() {
  var expiry = new Date();
  expiry.setDate(expiry.getDate() + 7);

  return jwt.sign({
    _id: this._id,
    mail: this.mail,
    name: this.name,
    exp: parseInt(expiry.getTime() / 1000),
  }, process.env.JWT_SECRET); // secret code from .env
};

module.exports = mongoose.model('user', userSchema);

在这里我用sequelize尝试了:

 var crypto = require('crypto');
    var jwt = require('jsonwebtoken');

    var User = sequelize.define('user', {
      name: Sequelize.STRING,
      mail: Sequelize.STRING,
      hash: Sequelize.STRING,
      salt: Sequelize.STRING


    });

    User.methods.setPassword = function(password) {
      this.salt = crypto.randomBytes(16).toString('hex');
      this.hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
    };

    User.methods.validPassword = function(password) {
      var hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
      return this.hash === hash;
    };

    User.methods.generateJwt = function() {
      var expiry = new Date();
      expiry.setDate(expiry.getDate() + 7);

      return jwt.sign({
        _id: this._id,
        mail: this.mail,
        name: this.name,
        exp: parseInt(expiry.getTime() / 1000),
      }, process.env.JWT_SECRET); // DO NOT KEEP YOUR SECRET IN THE CODE!
    };


module.exports = User;

我没有测试那个因为开发另一个部分但我需要知道你是否考虑过这个问题,我觉得它充满了错误。

提前谢谢

我将重点介绍使用实例方法定义模型,某些方法可能与passwordjs和猫鼬特定,您可能需要以不同的方式实现。

2 ways个定义模型。

  1. 使用sequelize.define就像您实现的方式一样,您可以使用User.prototype.yourMethod附加实例方法,因为User is a ES6 class
var User = sequelize.define('user', {
  name: DataTypes.STRING,
  mail: DataTypes.STRING,
  hash: DataTypes.STRING,
  salt: DataTypes.STRING,
/* ... */
});

User.prototype.validPassword = function(password) {
  var hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
  return this.hash === hash;
};

/*
If you want an equivalent of User.statics.yourStaticMethod = function() {}
or User.static('yourstaticmethod', function() {})
You can use the following
*/

User.yourStaticMethod = function() {};
  1. 您也可以extend Model
class User extends Model {
  static yourStaticMethod() {} // in mongoose equivalent to User.statics.yourStaticMethod = function() {}
  validPassword(password) {
    var hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
    return this.hash === hash;
  }
};

User.init({
  name: DataTypes.STRING,
  mail: DataTypes.STRING,
  hash: DataTypes.STRING,
  salt: DataTypes.STRING,
/* ... */
}, {
  sequelize,
  modelName: 'user'
});
