I''m trying to write a privileging system in Rails and getting confused with the usage of Module. Here''s what I want: #file app/controllers/application.rb class ApplicationController < ActionController::Base include PrivilegeSystem before_filter :check_privilege end #file lib/privilege_system.rb module PrivilegeSystem def check_privilege @session[''privileges''].each do |priv| return true if ???.include?(priv) end redirect_to(:controller => ''error'', :action=>''exceeded'') end end #file app/controllers/some_controller.rb class SomeController < ApplicationController privilege_level :hello => [:read, :write], :some_form => [:write] def hello end def some_form end end ----------------------------------- The problem is where to put the privilege_level routine and then once I''ve got one, where to store the data so it can be retrieved at the ??? above. I tried the following (in both environments.rb and privilege_system.rb): module ActionController module Dependencies module ClassMethods def privilege_level(privs) @@access = privs end def get_access_level(action) @@access || {})[action.to_sym] end end end end The data just goes off into the ether. I tried breakpointing but can''t make any sense of where it''s at when it''s called. Help me OB1 Kenobi... Shawn __________________________________ Yahoo! Music Unlimited Access over 1 million songs.
