Rhosync and Rhodes Architecture

Rhosync Object Model

class Mmap < ActiveRecord::Base
  belongs_to :user

class User < ActiveRecord::Base
  has_many :mmaps
  has_many :apps, :through=>:memberships
  has_many :memberships

class App < ActiveRecord::Base
  has_many :users, :through=>:memberships
  has_many :memberships
  has_many :sources

class Membership < ActiveRecord::Base
  belongs_to :app
  belongs_to :user

class Source < ActiveRecord::Base
  belongs_to :app
  attr_accessor :source_adapter,:current_user

Plain English:
  - I need to create an app:
    - I'll name it: "map611"
    - I do it once by hand
  - I need a source:
    - I'll name it "M6"
    - M6 will belong to map611 app
    - I do it once by hand
  - M6 needs to know about its source_adapter
    - I do it once by hand
  - Every user needs a membership to the app:
    - I force this at run-time during each user creation
