I’m having an odd problem… in application.rb I have:

helper\_method :admin?

…since I use this all the time in my views to test if the user is an  
administrator, of course. Pretty standard.

I thought I’d be able to use this in specific helpers, but I’m getting  
“method not found”:

undefined method `admin?’

I’m surprised the admin? method works in a view but not in the  
respective helper. Anything I’m missing? How can I use this method in  
helpers?

Thanks!
