嗨，我有这个型号：
user.js的
// app/models/user.js
// load the things we need
var Schema = require('mongoose').Schema;
var bcrypt = require('bcrypt-nodejs');
var db = require('mongoose');
// define the schema for our user model
// create the model for users and expose it to our app
module.exports = function(app){
var userSchema = Schema({
local : {
email : String,
password : String,
},
facebook : {
id : String,
token : String,
email : String,
name : String
},
twitter : {
id : String,
token : String,
displayName : String,
username : String
},
google : {
id : String,
token : String,
email : String,
name : String
}
});
// methods ======================
// generating a hash
userSchema.methods.generateHash = function(password) {
return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null);
};
// checking if password is valid
userSchema.methods.validPassword = function(password) {
return bcrypt.compareSync(password, this.local.password);
};
return db.model('User', userSchema);
};
post.js
var db = require('mongoose');
module.exports = function(app){
var Schema = require('mongoose').Schema;
var post = Schema({
title: String,
private: Boolean,
text: String,
tags: [],
createdAt: { type: Date, default: Date.now }
});
return db.model('post', post);
};
护照配置文件：
// config/passport.js
// load all the things we need
var db = require('../config/db_connect')();
var LocalStrategy = require('passport-local').Strategy;
// load up the user model
var User = db.model('User');
// expose this function to our app using module.exports
module.exports = function(passport) {
// =========================================================================
// passport session setup ==================================================
// =========================================================================
// required for persistent login sessions
// passport needs ability to serialize and unserialize users out of session
// used to serialize the user for the session
passport.serializeUser(function(user, done) {
done(null, user.id);
});
// used to deserialize the user
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
// =========================================================================
// LOCAL SIGNUP ============================================================
// =========================================================================
// we are using named strategies since we have one for login and one for signup
// by default, if there was no name, it would just be called 'local'
passport.use('local-signup', new LocalStrategy({
// by default, local strategy uses username and password, we will override with email
usernameField : 'email',
passwordField : 'password',
passReqToCallback : true // allows us to pass back the entire request to the callback
},
function(req, email, password, done) {
// asynchronous
// User.findOne wont fire unless data is sent back
process.nextTick(function() {
// find a user whose email is the same as the forms email
// we are checking to see if the user trying to login already exists
User.findOne({ 'local.email' : email }, function(err, user) {
// if there are any errors, return the error
if (err)
return done(err);
// check to see if theres already a user with that email
if (user) {
return done(null, false, req.flash('signupMessage', 'That email is already taken.'));
} else {
// if there is no user with that email
// create the user
var newUser = new User();
// set the user's local credentials
newUser.local.email = email;
newUser.local.password = newUser.generateHash(password);
// save the user
newUser.save(function(err) {
if (err)
throw err;
return done(null, newUser);
});
}
});
});
}));
};
至少我的app.js
var express = require('express')
, load = require('express-load')
, bodyParser = require('body-parser')
, cookieParser = require('cookie-parser')
, passport = require('passport')
, flash = require('connect-flash')
, mongoose = require('mongoose')
, session = require('express-session')
, app = express();
require('./config/passport')(passport);
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(cookieParser('blog'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
// required for passport
app.use(session({
secret: 'appsecret',
resave: false,
saveUninitialized: true,
cookie: {
secure: true,
maxAge: new Date(Date.now() + 3600000)
}
}));
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session
app.use(express.static(__dirname + '/public'));
load('models')
.then('controllers')
.then('routes')
.into(app);
require('./routes/login.js')(app, passport);
app.listen(3030, function(){
console.log("Blog no ar.");
});
但是当我尝试运行我的应用程序时，我得到了一个例外：
/home/caio/workspace/personal-blog/node_modules/mongoose/lib/index.js:323
throw new mongoose.Error.MissingSchemaError(name);
^
MissingSchemaError: Schema hasn't been registered for model "User".
Use mongoose.model(name, schema)

我正在注册我的用户模型，但是mongoose没有认识到，任何人都可以帮助我吗？
答案 0 :(得分：0)
在你的app.js中，首先加载mongoose。
var mongoose = require('./config/mongoose'),
express = require('./config/express');
var db = mongoose();
var app = express();
不要忘记注册模型。你的代码应该是
return db.model('User', userSchema);
答案 1 :(得分：0)
好吧，mongoose Model需要一个架构。
而不是：
var User = db.model('User');
做类似的事情：
var Schema = require('mongoose').Schema
var userSchema = new Schema({
name: {
type: String,
default: 'hahaha'
}
});
var User = db.model('User', userSchema);
