是否找不到application.rb定义的方法？

Question

I'm working on a project where I've inherited some legacy code from an old version of Rails (1 or 2, I think). After tinkering with it, I tried starting it up, but I'm running into trouble in one of my controllers. Specifically, the line @user = current_user || User.new @user = current_user || User.new is stating that current_user can't be found. After doing some digging, I see that def current_user is hanging out in my application.rb file. Why isn't the app loading this method?

Am I misunderstanding how application.rb is supposed to work?

(If it matters, this method seems to be protected, but I don't know how that would prevent the app from seeing this definition.)
