Module problems

I’m new at Ruby/Rails, so must have missed something obvious.

I’m trying to use the module “sortable_column_headers”, which I obtained
from https://svn.elctech.com/svn/public/sortable_column_headers/. When
I try to load a view that uses this module, I get the following error.
The line with “before_filter” is this:

    before_filter :init_sortable_column_headers

I’m running ruby 1.8.4.

Welcome. You’ll have more luck with rails questions here:

Many of us here don’t use rails, as this in a general ruby language
mailing list. But good luck!
