rails 3.1 authentication

I have the rails 3.1 authentication set up, how do I get it to make sure I authenticate system wide?

If you want everything controller to use Authentication then I would
suggest using a before_filter in the ApplicationController. Something
like this

class ApplicationController < ActionController::Base
  before_filter: some_authentication_method


Use before_filter in ApplicationController class?

If by system wide you mean every action on every controller you can
set up a before_filter on ApplicationController and check for the
current_user there.

Hope it helps.


I am currently using the devise gem for authentication. It provides a
great base for authentication so that you don't have to reinvent the
