我正在使用 Heroku/Mongolab（我已经用 MongoHQ 尝试过），标题显示了我的设置。这是我的 package.json：

"name": "metatf-web",
"version" : "0.0.3",
"dependencies": {
    "express": "*",
    "ejs": ">=0.4.2",
    "passport": "*",
    "passport-steam": "*",
    "validator": "*",
    "mongoose" : "*",
    "connect-mongo" : "latest",
    "mongodb" : "latest"
}

基本上，当我创建一个新用户时，我的数据库会覆盖数据库中的一个用户，但只是有时。这是我的用户架构：

/**
 * Module dependencies
 */
var mongoose = require('mongoose');
var Schema = mongoose.Schema;

/**
 * User Schema
 */
module.exports = function() {
  var Users = new Schema({
    steamid : { type: String }
    , regdate : { type: Date, default: Date.now }
    , avatar  : { type: String, default: "none" }
    , isadmin : { type: String, default: "no" }
  });
  mongoose.model("Users", Users);
};

这是我用来确定用户是否在数据库中的函数，如果不是，则为：

var checkIfUserAddToDbIfNot = function(req, res, next) {
  var steamID = req.user;
  require('./controllers/user_controller').get(steamID, function(err, doc) {
    console.log(doc);
    if (!doc) { // User not found
      require('./controllers/user_controller').create(steamID);
      console.log('User added');
    }
  });
  return next();
};

我的用户控制器（CRUD）：

/**
 * Module dependencies.
 */
 var mongoose = require('mongoose')
   , Users = mongoose.model("Users")
   , user = new Users();

// Create
exports.create = function (steamID) {
  if (steamID == 76561197991291041) { // Add me as an admin for when database resets.
    user.isadmin = 'yes';
  } else {
    user.isadmin = 'no';
  }
  user.steamid = steamID;
  user.save(function (err, callback) {
    if (err) throw err;
    console.log('User ' + user.steamid + ' added');
    console.log('Admin: ' + user.isadmin);
  });
};

// Read
exports.get = function (steamID, fn) {
  Users.findOne({ steamid: steamID }, function (err, doc) {
    if (err) return err;
    if (doc) {
      fn(null, doc);
    } else {
      fn(null, null); // User not found
    }
  });
};

这里是调用检查用户函数的地方：

app.get('/auth/steam/return',
  passport.authenticate('steam', { failureRedirect: '/' }), checkIfUserAddToDbIfNot, function (req, res) {
    res.redirect('/');
  });

最后是我的 connect-mongo 东西：

app.use(express.session({
  secret: 'dont be walmarting',
  store: new MongoStore(sess_conf.db),
  cookie: {
    maxAge: new Date(Date.now() + 1209600000), // DO NOT CHANGE
    expires: new Date(Date.now() + 1209600000) // DO NOT CHANGE
  },
  maxAge : new Date(Date.now() + 1209600000), // DO NOT CHANGE
  expires: new Date(Date.now() + 1209600000) // DO NOT CHANGE
}));

这里的任何帮助将不胜感激，我一生都无法弄清楚为什么用户被覆盖。我曾尝试在站点中添加新用户之前清除 cookie，因为我认为这是 Connect-Mongo 会话，但这不起作用。感谢任何可以帮助我的人。

编辑：我正在下面初始化 Passport 会话：

// Initialize Passport!  Also use passport.session() middleware, to support
// persistent login sessions (recommended).
app.use(passport.initialize());
app.use(passport.session());
app.use(app.router);
// END APP CONFIG (annotated)

我认为这是你的问题： 

var mongoose = require('mongoose')
   , Users = mongoose.model("Users")
   , user = new Users(); // <-- this creates a module variable `user`, but only once                             
                         //     (the first time the file is require()'d)

// Create
exports.create = function (steamID) {

  // ...which is being re-used every time this function is called.
  // Instead, you need to create the new user here:
  var user = new Users;

  if (steamID == 76561197991291041) { // Add me as an admin for when database resets.
    user.isadmin = 'yes';
  } else {
    user.isadmin = 'no';
  }
  user.steamid = steamID;
  user.save(function (err, callback) {
    if (err) throw err;
    console.log('User ' + user.steamid + ' added');
    console.log('Admin: ' + user.isadmin);
  });
};
