nodejs中使用mongoose保存数据 | Wukong's Blog

最近在学习mongdb

以下是使用mongoose模块来保存数据

var mongoose = require('mongoose');  
var moment = require('moment');  

// 连接字符串格式为mongodb://主机/数据库名  
mongoose.connect('mongodb://localhost/test');  
var db = mongoose.connection;  
//输出连接日志  
db.on('error', function callback() {  
    console.log("Connection error");  
});  

db.once('open', function callback() {  
    console.log("Mongo working!");  
});  

// 创建schema  
var Schema = mongoose.Schema;  
var userSchema = new Schema({  
    name: String,  
    age: Number,  
    createTime: {  
        type: Date,  
        default: moment().format('YYYY-MM-DD HH:mm:ss')  
    },  
    updateTime: {  
        type: Date,  
        default: moment().format('YYYY-MM-DD HH:mm:ss')  
    },  
    telphone: String  
});  
// 构建model  
var User = mongoose.model('User', userSchema);  
//构建model实例  
var userData = new User({  
    name: 'root',  
    age: 21,  
    telphone: '18766560229'  
});  

// 保存数据  
userData.save(function(err) {  
    if (err) {  
        console.log(err)  
    } else {  
        console.log('Save success');  
    }  
})

还有，输出信息有以下信息：
(node:7780) DeprecationWarning: Mongoose: mpromise (mongoose’s default promise library) is deprecated, plug in your own promise library instead: http://mongoosejs.com/docs/promises.html
也不不知道是什么意思，需要补充
