This is probably more of a ruby question than radiant but here goes…

I have two controllers in my extension that I’d love to inherit access  
rules (only\_allow\_access\_to) since they share the same rules.

Basically, I’d like to put:  
only\_allow\_access\_to :index, :new, :edit, :remove,  
:when =\> [:developer, :admin],  
:denied\_url =\> { :controller =\> ‘page’, :action =\> ‘index’ },  
:denied\_message =\> ‘You must have developer or admin privileges to  
perform this action.’

in my parent controller class and have the two child classes inherit it.  
The only\_allow\_access\_to method is added as a part of radiant’s  
lib/login\_system.rb and the method call in the parent doesn’t seem to  
inherit. Any clever way to do this?

This isn’t a major show stopper as I can just stick the rules into the  
two child classes – but finding a way to make this work has become sort  
of a mission at this point 🙂
