MissingSchemaError:尚未为模型“用户"注册架构 [英] MissingSchemaError: Schema hasn't been registered for model "User"

问题描述

在我的 models/user.js 文件中:

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var userSchema = new Schema({
    (define schema)
});
...
(save user)
...
(check password)
...
mongoose.model('User', userSchema);

在我的 router/index.js 中，我有:

var mongoose = require('mongoose');
var User = mongoose.model('User');

抛出错误:

MissingSchemaError: Schema hasn't been registered for model "User".

但是，如果在 user.js 中，我会(在最后一行)

If however, in user.js, I do (in the last line)

module.exports = mongoose.model('User', userSchema);

在 index.js 中，我执行 var User = require('../models/User');，然后一切正常.

and in index.js I do var User = require('../models/User');, then everything works.

但它不应该，因为在 config/pass.js 我正在做 var User = mongoose.model('User'); 并且它完美地工作.

But it should not, because in config/pass.js I am doing var User = mongoose.model('User'); and it's working flawlessly.

require('../models/User'); 语法不适用于 Ubuntu，但适用于我的 Mac.

The require('../models/User'); syntax isn't working on Ubuntu, but is on my Mac.

我该怎么办?我如何解决它?我查看了大量示例应用程序，包括 MEAN 但没有什么是真正有用的.

What should I do? How do I fix it? I have looked at tons of sample apps, including MEAN but nothing was really helpful.

推荐答案

我在尝试 MEAN 教程时遇到了同样的问题.

I got the same problem when I am trying the MEAN tutorial.

经过一番研究，我发现在 app.js 中，如果我将 require("./models/User") 放在 var routes = require("./routes/index") 之前，那么它就可以工作.

After done a little bit research, I found that in app.js, if I put require("./models/User") before var routes = require("./routes/index"), then it works.

像这样:

mongoose.connect("mongodb://localhost/news");
require("./models/Posts");
require("./models/Comments");

var routes = require('./routes/index');
var users = require('./routes/users');

var app = express();
