Mongoose: `TypeError: undefined is not a function` when creating a new model

I am using mongoose to connect to an MongoLab database, I have separated my database model and stuff as a separate module form the rest of my code. I am trying to create an new Model and then save it to the database. unfortunately, it keeps throwing an error: TypeError: undefined is not a function

This is my database module

var mongoose = require('mongoose');

module.exports = (function() {
    var database = {};

    database.Schema = mongoose.Schema,
        ObjectID = database.Schema.ObjectID;

    database.Task = new database.Schema({
        task: String, 
    });

    database.Tasks = mongoose.model('Tasks', database.Task);

    return database;
});

Here is the code that is generating the error:

var express = require('express');
var database = require('./database');

var router = express.Router();

router.get('/', function(req, res) {
    res.render('../views/index.jade', {title: 'TODO'});
}); 

router.post('/', function(req, res) {
    // res.render('../views/index.jade', {title: 'TODO', tasks: req.body.name});
    var task = new database.Task(req.body.name);
    task.save(function(err) {
        if(!err) {
            console.log('Task: ' + task + 'successfully saved!');
        } else {
            res.render('../views/index.jade', {title: 'Error', tasks: 'Error: ' + err});
        }
    });
});

module.exports = router;

I think it has to deal with the scope of database.js but I am not to sure. How can I fix this problem?

Here is the full Stacktrace

.save() is a method on mongoose models, not schemas. Try:

var task = new database.Tasks(req.body.name); task.save(...);
