Hello,

How can i apply a before\_filter on all controllers in application.rb  
without some specific controllers. Is there something like :only and  
:except for controllers like there is for methods?

You can use skip\_after\_filter, skip\_before\_filter, or skip\_filter to  
skip filters in a controller.
