Ajax Star Rating in Rails 2.1

I've searched high and low and come up with:

http://blog.aisleten.com/2007/05/03/ajax-css-star-rating-with-acts_as_rateable/ http://www.naffis.com/blog/articles/2006/08/31/rails-ajax-star-rating-system

But they are all pretty old. Even searching the list I'm only seeing incomplete conversations of people trying to implement something. The first one is filled with text errors (so it seems anyway) so I'm having a big difficulty getting it working. Does anyone know of more recent information on using acts_as_rated or acts_as_rateable doing an Ajax submission similar to those above?

Much thanks, Tim

Well it just seems little information is out there with current working assistance to show how to do this. For those of you that are curious too on how to do this perhaps you wouldn't mind voting up at http://railscasts.uservoice.com/pages/general/suggestions/33964 - maybe Ryan and RailsCasts might cover something.

Thanks,

Tim
