Hi,

I have two plugins with rails active-rbac and actionflow. Actionflow  
uses his own controller, so I have two super controllers one for the  
application (ApplicationController) and one for actionflow  
(FlowApplicationController with base ActionFlow::Base). Now I want to  
use functionality in both controllers like authorization en  
authentication. What is the best way to such a thing, must I build a  
class a module, etc. And are there examples with a solution for my  
problem.

Thanks in advance.

Thanks for your reply. So I’ll put the code in a seperate module. Is  
there some example how to do this?

don’t know about that. There’s not really much to explain - you just  
do it.
