mixing in action view helper methods in a class

I've got a class where I would like to use the TextHelper truncate method. It's not a M, V or C but is called by a controller. I figured I should be able to mixin the TextHelper in order to have access to the truncate method. But I can't get it to work. I'm new to Ruby and ROR, so I haven't done mixins before.

Here's what I've got...

class Searcher   require 'action_view/helpers/text_helper'   include ActionView::Helpers::TextHelper

I get a NoMethodError: undefined method `truncate' for Searcher:Class. How do I get this to work?

By the way, I apologize if this has already been answered in this group (as is likely), but I did a search and couldn't find it.

Thanks, Myron
