Simple passive model implementation

SModel
==

Simple passive model implementation.

Usage:

class TrackInfo
  include SModel::BaseModel
  element :number, Integer
  element :description, String, :default_value => 'it`s another track'
  element :file_name, String
  element :file_url, String
end

class MoreInfo
  include SModel::BaseModel
  element :credits, String
end

class MusicAlbum 
  include SModel::BaseModel
  element :id, String
  element :name, String
  element :create_date, DateTime  
  has_many :tracks, TrackInfo
  has_many :feedback, String
  has_one :more, MoreInfo
end

Now we can use it like that:

album = MusicAlbum.new

album.set_value :name, ‘Machine memory shells’

album.set_value :create_date, Time.now

album.set_value ‘tracks > 0 > number’, 1

album.set_value ‘tracks > 0 > file_name’, ‘Summer Breeze.mp3’

album.set_value ‘more > credits’, ‘Some credits here’

album.to_hash

This assignation is also valid:

album.set_value ‘feedback’, [‘why only 5?’, ‘it`s like idm’, ‘when will be mbwm?’]

Now you can pass result hash to view, db, checksum calc or others.
