Application Controller instance variable available to all views

Currently, I have this on the application controller...   def company_name     User.find_by_id(session[:user_id]).account.name   end

So then in each controller I have to add this, which is not very DRY. The @company_id needs to be used in almost every page and it's accessed on the application.html.erb on a link @company_id = company_id (has to be added to EVERY CONTROLLER)

How can I NOT have to add the above line in every controller? Is there a way to add it to the application controller and have it available to application.html.erb regardless on what page im on?

You asked a nearly identical question a few days ago. Please read http://groups.google.com/group/rubyonrails-talk/msg/c8a1cc193e362316 again, where I answered this exact question.

A before_filter is not restricted to use with a regular controller, it can also be used with the application_controller.
