Rails - Dec 2005 - Application.rb / Application_Helper.rb / DRY help

Hi all,

I have defined the following method in both application.rb and
application_helper.rb:

  def still_logged_in?
    !session[:user_id].nil?
  end

This method is called in a before_filter in my application.rb, as well
as in my layout/application.rhtml and view/user/login.rhtml (for
showing a login / logout button, etc.)

I had to put it both places, otherwise I would get an ''undefined
method'' error.

Is there a better approach I should take to DRY this duplicate logic up?

Any suggestions appreciated!

Thanks,
Best Regards,
EJC

helper_method will make still_logged_in? available to your views as well.
