## app/controllers/application_controller.rb

  helper :all
  protect_from_forgery
  include Authentication

## lib/authentication.rb

module Authentication
  filter_parameter_logging :password, :password_confirmation
  helper_method :current_user

  private
    def current_user
      return @current_user if defined?(@current_user)
      @current_user = current_user_session && current_user_session.user
    end
end
