编译猫鼬后无法覆盖模型

编译猫鼬后无法覆盖模型

发生错误是因为您已经定义了一个架构，然后又在定义该架构。通常，您应该做的是一次实例化架构，然后在需要它时让一个全局对象调用它。

例如：

user_model.js

var mongoose = require('mongoose');var Schema = mongoose.Schema;var userSchema = new Schema({   name:String,   email:String,   password:String,   phone:Number,   _enabled:Boolean});module.exports = mongoose.model('users', userSchema);

check.js

var mongoose = require('mongoose');var User = require('./user_model.js');var db = mongoose.createConnection('localhost', 'event-db');db.on('error', console.error.bind(console, 'connection error:'));var a1= db.once('open',function(){  User.find({},{},function (err, users) {    mongoose.connection.close();    console.log("Username supplied"+username);    //doSomethingHere   })});

insert.js

var mongoose = require('mongoose');var User = require('./user_model.js');mongoose.connect('mongodb://localhost/event-db');var new_user = new User({    name:req.body.name  , email: req.body.email  , password: req.body.password  , phone: req.body.phone  , _enabled:false });new_user.save(function(err){  if(err) console.log(err); });
