Rails - Jul 2006 - Refactoring common code to module

Hello Ruby users,

I am stuck with the following problem:


I have an access control list system, with multiple group, section and 
base classes. There are several section types (AroSection, AxoSection, 
AclSection etc.), several group types (AxoGroup, AroGroup) and several 
base Types (Acl, Axo, Aro, Aco).

These share some common funcionality that only differs by name of the 
associations.

module GACL

  class AclSection < ActiveRecord::Base
    set_table_name "gacl_acl_sections"

    has_many :acls, :dependent => true

    validates_presence_of :name, :value
    validates_numericality_of :order_value
    validates_uniqueness_of :value

    def instance_method_for_acl (would be the same functionality for the 
others, too)
     ...
     acls.each do |acl|
       ...
     end
    end
  end
end

Is it possible to do some refactoring, so I only have to define my code 
once and the method names get used from some parameter or extracted from 
the class name?

Best regards
Gregor
