var mongoose = require('mongoose'); 
var db  = mongoose.createConnection('mongodb://127.0.0.1:27111/foo'); 

var Schema = mongoose.Schema; 
var Tasks = new Schema({ 
    project: String,

mongoose.model('Task', Tasks); 

var Task =mongoose.model('Task'); 

var task = new Task();  
task.project = 'bikeshed'; 
task.description = 'paint the bideshed red.'; 
task.save(function(err){ //save 
    if(err) throw err; 
    console.log('Task saved');

//搜索文档 
Task.find({"project": 'bikeshed'}, function(err, tasks) { 
    for (var i = 0 ; i < task.length ; i++) { 
    console.log('--------------ID:' + tasks[i]._id);

相反的mongoose.createConnection，使用mongoose.connect

var db = mongoose.connect('mongodb://127.0.0.1:27111/foo');
