Hey, I’m trying as a test to make a simple wiki with RoR. I wanted to  
use restful\_authentication plugin, which creates a couple controllers,  
one of which is the Sessions controller. It has all the ‘logged\_in?’  
checks and the ‘current\_user’ variable. However, I don’t know how to use  
another controller’s variables/methods from within another controller.  
Ie, in my Wiki controller, or in it’s views, I can’t make these sort of  
calls to make sure the user is logged in. Can anyone guide me in the  
right direction?

restful\_authentication does provide all those extras, but they live in  
the .lib file, not in the controllers. You should be able to called  
logged\_in?, current\_user etc from any controller.

They key is to include the restful\_auth lib in application\_controller.  
As long as you do this, all the functionality will be available  
site-wide.

Aah, so in the application controller, just a quick ‘include  
“restful\_auth”’ at the top o’ the file?

I believe it’s actually “include AuthenticatedSystem”. When you run  
script/generate to make the restful\_auth controllers, it will put that  
line at the top of the Sessions controller. The docs recommend you move  
it to the application controller so it’s globally available.
