Mean Stack MissingSchemaError：架构尚未注册模型“User”

我已经尝试了许多堆栈溢出解决scheme，但没有在我的情况下工作…这是我的代码… server.js这是我的应用程序的入口点。

process.env.NODE_ENV = process.env.NODE_ENV || 'development'; var config = require('./config/config'), mongoose = require('./config/mongoose'), passport = require('./config/passport'), express = require('./config/express'); var passport = passport(); var db = mongoose(), app = express(); app.listen(config.port); module.exports = app; console.log(process.env.NODE_ENV + ' server running at http://localhost:' + config.port); 

我的config.js是

 module.exports = require('./env/' + process.env.NODE_ENV + '.js'); 

Mongoos.js

 var config = require('./config'), mongoose = require('mongoose'); module.exports = function() { var db = mongoose.connect(config.db); require('../app/models/user.server.model'); return db; }; 

Passport.js

 var mongoose = require('mongoose'); var passport = require('passport'); var User = mongoose.model('User'); module.exports = function() { passport.serializeUser(function(user, done) { done(null, user.id); }); passport.deserializeUser(function(id, done) { User.findOne( {_id: id}, '-password', function(err, user) { done(err, user); } ); }); require('./strategies/local.js')(); }; 

Express.js

 var config = require('./config'), express = require('express'), bodyParser = require('body-parser'), passport = require('passport'); module.exports = function() { var app = express(); var session = require('express-session'); var flash = require('connect-flash'); app.use(flash()); app.use(session({ saveUninitialized: true, resave: true, secret: 'OurSuperSecretCookieSecret' })); app.use(bodyParser.urlencoded({ extended: true })); //use this code before any route definitions app.use(passport.initialize()); app.use(passport.session()); app.use(bodyParser.json()); app.set('views', './app/views'); app.set('view engine', 'ejs'); require('../app/routes/index.server.routes.js')(app); require('../app/routes/users.server.routes.js')(app); app.use(express.static('./public')); return app; }; 

最后模态文件users.server.model.js在这里。

 var mongoose = require('mongoose'), crypto = require('crypto'), Schema = mongoose.Schema; var UserSchema = new Schema({ name: String, email: String, username: { type: String, trim: true, unique: true }, password: String, provider: String, providerId: String, providerData: {}, todos: {}//we will use this in the next tutorial to store TODOs }); UserSchema.pre('save', function(next) { if (this.password) { var md5 = crypto.createHash('md5'); this.password = md5.update(this.password).digest('hex'); } next(); } ); UserSchema.methods.authenticate = function(password) { var md5 = crypto.createHash('md5'); md5 = md5.update(password).digest('hex'); return this.password === md5; }; UserSchema.statics.findUniqueUsername = function(username, suffix, callback) { var _this = this; var possibleUsername = username + (suffix || ''); _this.findOne( {username: possibleUsername}, function(err, user) { if (!err) { if (!user) { callback(possibleUsername); } else { return _this.findUniqueUsername(username, (suffix || 0) + 1, callback); } } else { callback(null); } } ); }; var User = mongoose.model('User', UserSchema); exports = User; 

在最后两行我已经尝试了不同的方法，我也尝试了简单的mongoose.model（'用户'，UserSchema）; 这一行，但没有奏效。 我正在使用本教程https://hackhands.com/mongodb-crud-mvc-way-with-passport-authentication/

Answer 1

您正在注册模型之前加载您的/configuration/护照。 您需要先注册您的模型的文件。 所以像这样的东西：

 var config = require('./config/config'), mongoose = require('./config/mongoose'), // require the file that has your model model = require('./path/to/users.server.model'), passport = require('./config/passport'), express = require('./config/express'); var passport = passport(); var db = mongoose(), app = express(); 

或者，您可以在调用var User = mongoose.model('User');之前在/config/passport.js中包含该文件var User = mongoose.model('User');
