编译 Mongoose 后无法覆盖模型 [英] Cannot overwrite model once compiled Mongoose

问题描述

不知道我做错了什么，这是我的 check.js

Not Sure what I'm doing wrong, here is my check.js

var db = mongoose.createConnection('localhost', 'event-db');
db.on('error', console.error.bind(console, 'connection error:'));

var a1= db.once('open',function(){
var user = mongoose.model('users',{ 
       name:String,
       email:String,
       password:String,
       phone:Number,
      _enabled:Boolean
     });

user.find({},{},function (err, users) {
    mongoose.connection.close();
    console.log("Username supplied"+username);
    //doSomethingHere })
    });

这是我的 insert.js

and here is my insert.js

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/event-db')

var user = mongoose.model('users',{
     name:String,
     email:String,
     password: String,
     phone:Number,
     _enabled:Boolean
   });

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); 
   });

每当我尝试运行 check.js 时，我都会收到此错误

Whenever I'm trying to run check.js, I'm getting this error

一旦编译就无法覆盖用户"模型.

我知道这个错误是由于架构不匹配造成的，但我看不出这是在哪里发生的?我对猫鼬和 nodeJS 还很陌生.

I understand that this error comes due to mismatching of Schema, but I cannot see where this is happening ? I'm pretty new to mongoose and nodeJS.

这是我从 MongoDB 的客户端界面得到的信息:

Here is what I'm getting from the client interface of my MongoDB:

MongoDB shell version: 2.4.6 connecting to: test 
> use event-db 
  switched to db event-db 
> db.users.find() 
  { "_id" : ObjectId("52457d8718f83293205aaa95"), 
    "name" : "MyName", 
    "email" : "[e-mail]", 
    "password" : "myPassword", 
    "phone" : 900001123, 
    "_enable" : true 
  }

推荐答案

出现此错误的另一个原因是，如果您在不同的文件中使用相同的模型，但您的 require 路径具有不同的大小写.

Another reason you might get this error is if you use the same model in different files but your require path has a different case.

例如，在我的情况下，我在一个文件中有 require('./models/User')，然后在另一个需要访问 User 模型的文件中，我有 require('./models/user').

For example, in my situation I had require('./models/User') in one file, and then in another file where I needed access to the User model, I had require('./models/user').

我猜是查找模块 &猫鼬将其视为不同的文件.一旦我确定大小写匹配，就不再是问题了.

I guess the lookup for modules & mongoose is treating it as a different file. Once I made sure the case matched in both it was no longer an issue.
