http://mongoosejs.com (GitHub)에 대하여 알아보자. (mongoose의 light-weight ORM version으로 몽고리안-mongolian-도 존재한다)


1) mongoose의 schema는 extension = controller 이다 : Node.js 소스 

/**

* Module dependencies.

*/


var express = require('express')

, routes = require('./routes');


var mongoose = require('mongoose');

var Schema = mongoose.Schema;


mongoose.connect('mongodb://localhost/mydb');


var UserSchema = new Schema({ // MVC controller

age : Number,

name: String,

sex: Boolean

});


var UserModel = mongoose.model('users', UserSchema); // Model ---> collection


var app = module.exports = express.createServer();


// Configuration


app.configure(function(){

app.set('views', __dirname + '/views');

app.set('view engine', 'jade');

app.use(express.bodyParser());

app.use(express.methodOverride());

app.use(app.router);

app.use(express.static(__dirname + '/public'));

});


app.configure('development', function(){

app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));

});


app.configure('production', function(){

app.use(express.errorHandler());

});


// Routes


app.get('/', routes.index);


app.param('name', function (req, res, next, name) {

UserModel.find({ name: name }, function (err, docs) {

req.user = docs[0];

next();

});

});


app.get('/users/:name', function (req, res) {

// res.json({ user: req.user });

res.render('./show',{ title: 'Express User',user: req.user });

});


app.get('/users/:name/edit', function (req, res) {

res.render('./edit',{ title: 'Express User',user: req.user });

});


app.get('/users', function (req, res) {

// res.json({ user: req.user });

UserModel.find({},function(err,docs) {

res.render('./users', { title: 'Express User', users: docs });

});

});


app.get('/user/new', function (req, res) {

res.render('new',{layout:false}); //,user:{name:'',age:0,sex:false}}); //,{ title: 'Express User'});

});


app.del('/users/:name', function (req, res) {


UserModel.remove({ name: req.params.name }, function (err) {

res.redirect('/users');

});


});


app.post('/users', function (req, res) {

var b = req.body;

new UserModel({

name: b.name,

age: b.age,

sex:b.sex

}).save(function (err, user) {

if (err) res.json(err);


res.redirect('/users/' + user.name);

});

});


app.put('/users/:name/edit', function (req, res) {

var b = req.body;

UserModel.update(

{ name: req.params.name },

{ name: b.name, age: b.age, sex: b.sex },

function (err) {

res.redirect('/users/' + b.name);

}

);


});


app.listen(process.env.port || 3000);

console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);


  - Jade 소스

h1 Edit User


form(method='POST', action('/users/#{user.name}'))

input(type='hidden',name='_method',value='PUT')

p Name:

input#name(type='text', name='name', value='#{user.name}')

p Age:

input#age(type='number', name='age', value='#{user.age}')

p Sex:

input#sex(type='boolean', name='sex', value='#{user.sex}')

p

button(type='submit') Update


h1 New User


form(method='POST', action= '/users')

p Name:

input#name(type='text',name='name')

p Age:

input#age(type='number',name='age')

p Sex:

input#sex(type='boolean',name='sex')

button(type='submit') Create


h1 #{user.name}


ul

li Age: #{user.age}

li Sex: #{user.sex}


ul

li: a(href='/users/#{user.name}/edit') Edit

li

form(action='/users/#{user.name}' , method='POST')

input(type='hidden',name='_method',value='DELETE')

button(type='submit') Delete


h1 All Users


ul

each user in users

li: a(href='/users/#{user.name}') #{user.name} #{user.age} #{user.sex}
