Rails - Jan 2006 - Handling specific page editing permissions for members

Hi all,

I''m building a custom content management system for a website in Rails.
What''s the best way of restricting members to being able to edit 
specific pages?

For example, a members might belong to a branch, along with many other 
members (n:1 relationship). But I only want specific members to be able 
to edit their branch page on the site, and no other branch pages.

Should I be making a join table with an extra attribute for permission 
to edit? I understand that it''s a bit messy in rails 1.0, and 1.1 will 
have has_many :members, :through => branch_permissions, or something 
like that. Is it worth waiting, or is there a better way?

Thanks!

Tom
