Question

我正在尝试使用节点和护照构建登录和注册系统这是架构

（型号/ user.js的）

var mongoose = require('mongoose');  
var bcrypt = require('bcryptjs');

//User Schema
var UserSchema = mongoose.Schema({
    username: {
        tye: String,
        index: true
    },
    password: {
        type: String
    },
    email: {
        type: String
    },
    name: {
        type: String
    }
});

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

module.exports.createUser = function(newUser, callback){
    bcrypt.genSalt(10, function(err, salt) {
    bcrypt.hash(newUser.password, salt, function(err, hash) {
        newUser.password = hash;
        newUser.save(callback);
    });
});
}

我只使用了单个架构UserSchema

错误是

C:\xampp\htdocs\loginapp\node_modules\mongoose\lib\schema.js:646
    throw new TypeError('Undefined type `' + name + '` at `' + path +
    ^

TypeError: Undefined type `undefined` at `username.index`
  Did you try nesting Schemas? You can only nest using refs or arrays.

这是我的路由文件（routes / user.js）

var express = require('express');
var router = express.Router();

var user = require('../models/user');

//Register
router.get('/register', function(req,res){
    res.render('register');
});

//Login
router.get('/login', function(req,res){
    res.render('login');
});

//Register User
router.post('/register', function(req,res){
   var name = req.body.name;
    var email = req.body.email;
    var username = req.body.username;
    var password = req.body.password;
    var password2 = req.body.password2;

    //Validation
    req.checkBody('name', 'Name is required').notEmpty();
    req.checkBody('email', 'Email is required').notEmpty();
    req.checkBody('email', 'Email is not valid').isEmail();
    req.checkBody('username', 'Username is required').notEmpty();
    req.checkBody('password', 'Password is required').notEmpty();
    req.checkBody('password2', 'Password do not match').equals(req.body.password);

    var errors = req.validationErrors();
    if(errors){
       res.render('register', {
           errors: errors
       });
    }
    else{
        var newUser = new User({
            name: name,
            email: email,
            username: username,
            password: password
        });
        User.createUser(newUser, function(err, user){
            if(err) throw err;
            console.log(user);
        });

        req.flash('success_msg', 'You are registered and can now login');
        res.redirect('/users/login'); 
    }
});


module.exports = router;

我无法找到错误它说你有嵌套模式所以使用refs但我只使用了单一模式我正在尝试使用节点和护照构建登录和注册系统 cameit 我正在尝试使用节点和护照构建登录和注册系统我的app.js完全正常工作包括模式后错误来说你有嵌套模式所以使用refs但我只使用单一模式

Answer 1

您在username的类型声明上有拼写错误。

username: {
  tye: String, // typo here, should read 'type'
  index: true
},

单个模式但仍显示嵌套模式错误
