I always need to apply alternating item styles when outputting a collection, here''s what I''ve been using recently. In the app helper I define this method: def alternate(items,alt=false items.map{|i| i.class}.each { |k| k.class_eval {attr_accessor :alt}} items.each { |i| i.alt, alt = alt, !alt } end When I call the partial I wrap the collection with this method:

I''m having trouble succesfully getting access to the ActionView::Helpers::TextHelper.strip_tags method from one of my controllers.

I have a model that deals with HTML and I want to use the text_helper.sanitize method to strip the HTML of Javascript.
