Hi   I have a function in ApplicationHelper say an example

def url_needed   if current_user.is_staff?     home_url   else     another_url   end end

And in ApplicationController what I did is

   def check_for_the_feature        flash[:notice] = 'You have no permission to do this.'        self.extend ApplicationHelper        redirect_to url_needed    end

Is there any problem extending helper like this.

Thanks
