autocomplete under Rails 3.1

Requirements: Get coffee-script installed (refer above)

Ref: http://babinho.net/2011/05/autocomplete-fields-in-rails-3-1-with-jquery-ui/

To use this I had to download jquery-ui (http://jqueryui.com/download) and select Autocomplete

Example application with autocomplete
