fromObject.js

var db = /* ... */

var obj = {
    _id: '21245b528adfad75b0480baf',
    email: 'jeansebtr@xpensia.com',
    username: 'jeansebtr',
    fullname: 'Jean-Sébastien Tremblay'
};


var User = db.model('User');
var user = new User(undefined, undefined, true).init(obj);

user.fullname = 'Jean-Seb Tremblay';
user.save(function(err) {
   console.log(err); // null
});

user.js

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var User = module.exports = new Schema({
    // ...
});

User.statics.deserialize = function(txt) {
    var User = this.model('User');
    var obj = JSON.parse(txt);
    return new User(undefined, undefined, true).init(obj);
};
