mongoose dao

mongoosedao = mongoose data access object

Install

npm install --save mongoosedao

Usages

require('./db');

var User = require('./User');

User.create({"username":"sss","password":"password"},function(err, user){
  console.log(user);
});

User.delete({"username":"sss","password":"password"},function(err, user){
  console.log(user);
});

扩展

User.model is a mongoose model. You can do all as mongoose model。

more features

• statics
• methods
• pre or post hook
• aggregation

比如直接扩展方法

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var Promise = require('bluebird');

var User = require('../app/models/user');

User.schema.statics.find_by_openid = function(openid, cb) {
  console.log('find_by_openid...')
};

// 此处必须要重置一下model
User = mongoose.model('User', User.schema);

var MongooseDao       = require('mongoosedao');

var UserDao = new MongooseDao(Test);

UserDao.model.find_by_openid({}, function(err,docs){
  // console.dir(docs);
  process.exit();
}); 

当然我们更推荐的是在model定义上直接加

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

 
UserSchema = new Schema({
  username: {
    type: String,
    required: true,
    index: {
      unique: true
    }
  },
  password: {
    type: String,
    required: true
  },
  avatar: String,
  address: String,
  created_at: {
    type: Date,
    "default": Date.now
  }
});

UserSchema.methods.find_by_name = function(cb) {
  return this.model('UserModel').find({
    username: this.username
  }, cb);
};

UserSchema.methods.is_exist = function(cb) {
  var query;
  query = {
    username: this.username,
    password: this.password
  };
  return this.model('UserModel').findOne(query, cb);
};

UserSchema.statics.delete_by_name = function(name, cb_succ, cb_fail) {};

var UserModel = mongoose.model('UserModel', UserSchema);

var MongooseDao = require('../../');

 
var MeetingDao = new MongooseDao(UserModel);
 
module.exports = MeetingDao;

只要mongoose支持的，使用mongoosedao都可以完成，甚至更好
