Overview

SimpleAccessControl

Acknowledgements: I give all credit to Ezra and Technoweenie for their two plugins which inspired the interface design and a lot of the code for this one.

SimpleAccessControl is a streamlined, intuitive authorisation system. It derives heavily from acl_system2 and has made clear some problems which plagued the author when first using it. Some fixes to acl_system2’s design:

* a normal Rails syntax:
      access_rule 'admin', :only => :index
      access_rule '(moderator || admin)', :only => :new
* error handling for helper methods (permit? bombs out with current_user == nil)
* one-line parser, easy to replace or alter
* proper before_filter usage, meaning access rules are parsed only when needed
* no overrideable default (which I found counter-intuitive in the end)

Also, it has two methods, access_control and permit?, for those moving from acl_system2.

But, let me stress, everyone likes a slightly different system, so this one may not be your style. I find it synchronises very well with the interface of Acts as Authenticated (even though I have modified it so much that it’s now called Authenticated Cookie).
