ConcernedWith
=============

Simple way to separate model and controller concerns into separate files. Code is from Rick Olson's altered_beast project.


Example
=======

# app/models/user.rb
class User < ActiveRecord::Base
  concerned_with :validations, :authentication
end

# app/models/user/validations.rb
class User < ActiveRecord::Base
  validates_presence_of :name
end

#app/models/user/authentication.rb
class User < ActiveRecord::Base
  def self.authenticate(name, password)
    find_by_name_and_password(name, password)
  end
end

#app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  concerned_with :authentication
end

#app/controllers/application/authentication.rb
class ApplicationController < ActionController::Base
  def logged_in?
    false
  end
end
