Alternative Extending Mongoose.js Schemas with functions declared elsewhere

gistfile1.js

// models/player.js
var mongoose = require('mongoose'),
    Schema   = mongoose.Schema;

var Player= new Schema({
  name: String
});

Player.statics = {
  foo: function() {
    console.log('foo');
  }
}

Player.methods = {
  bar: function() {
    console.log('bar');
  }
}

module.exports = mongoose.model('players', Player);

// database/schema.js
var mongoose = require('mongoose'),
    Schema   = mongoose.Schema;

connect = function(db, cb) {
  mongoose.connect(db);
  var Player = require('../models/player');

  return cb({
    Player: Player
  });
};

module.exports = { connect: connect };

// In Node REPL
> db = require('./database/schema');
> models = db.connect('mongodb://localhost/db', function(a) { return a });
> models.Player
{ [Function: model] modelName: 'players', foo: [Function] }
> models.Player.foo()
foo
> player = new models.Player();
{ _id: 5048faa8abb6407343000002 }
> player.bar()
bar
