user.create()
.then(function(responce){
    // do something with responce
})
.catch(function(error){
    // error ...
})

// use nested models
user.gender.isMale() // true

// send user data to server to update user data
var user = new User({
    id: 1,
    first_name: 'john',
    last_name: 'doe',
    gender: {
        id: 1,
