Rails - Mar 2008 - GateKeeper 0.2 - Model Level Permissions Management

GateKeeper 0.2 is now available.

GateKeeper is a Ruby on Rails plugin providing natural language commands 
to intuitively manage complex access/security permissions on 
ActiveRecord models.  Permissions may be based on user''s system wide 
roles (Admin, Moderator, Employee of the Month) and on user''s 
relationship to individual records through ActiveRecord associations.

Version 0.2 adds traversal of eagerly loaded associations to verify read 
permissions on loaded objects.

Rdocs and installation instructions available at 
http://gatekeeper.rubyforge.org/


As an appetizer, here are some sample permission declarations you can 
add to your models for GateKeeper to enforce.

class Article < ActiveRecord::Base
  crudable_by_admin
  crudable_by_my_author
  readable_by_supervisor_of_my_author
  updateable_by_supervisor_of_my_author :unless => :first_draft?
  readable_by_premium_subscriber :if => :published?
  destroyable_as_my_author  #inherits ''destroy'' permissions
from author
  readable_by_guest :if => lambda { |article| article.published_on < 
3.months.ago }
  etc. etc. etc
