Hi
Since upgrading Rails my application generates errors for some (but not
all) of my controllers. Something to do with Helpers - which I don''t
use. I have tried freshly installing Ruby and Rails but it doesn''t
help.
Thanks for any help
Peter

I have found a workaround to the problem:- Delete all your empty helper files This suggests that Rails is (incorrectly?) expecting something in the helper file besides:- module FooHelper end Peter
Peter, Did you update your environment.rb? What does your logfile say? I seem to remember that the NameError error wasn''t always a useful message when getting it from the browser, so scout your logfile. Rails doesn''t expect anything but module FooHelper;end; in helpers -- johan On Apr 1, 2005 2:34 PM, Cutting Peter <Peter.Cutting-CwpgxV1jTAxWk0Htik3J/w@public.gmane.org> wrote:> I have found a workaround to the problem:- > Delete all your empty helper files > > This suggests that Rails is (incorrectly?) expecting something in the > helper file besides:- > module FooHelper > end > > Peter > > _______________________________________________ > Rails mailing list > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails >
