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

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


Example
=======

== for Controllers

# app/controllers/application.rb
class ApplicationController < ActionController::Base
  concerned_with :rescues
end

# app/controllers/application_controller/rescues.rb
class ApplicationController < ActionController::Base
  rescue_from ActionController::RoutingError, :with => :route_not_found

  protected

  def route_not_found
    render :text => 'Page is not exist', :status => :not_found
  end
end


== for Models

# 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
