Authorization is a project mainly written in Ruby, based on the MIT license.
Basic authorization for Rails (3.0)
The authorization method is inspired by the authorization recipe in "Rails Recipes" and this blog entry:
http://metaautonomo.us/2008/09/30/easy-role-based-authorization
Each user belongs to a single Role. Each role has multiple permissions identified by their name. You can check if a user belongs to role with the dynamic "is_role?" method:
user.is_admin? user.is_admin_or_editor? etc ...
You can check if the user has permission to do something using the "can_xyz?" method:
user.can_edit_page? user.can_view_published_page? user.can_view_unpublished_page?
Example goes here.
