rails 3 auto complete (prototypejs)

I'm looking for a good auto complete plugin for rails3, based on prototyp开发者_如何学Pythone.

The plugin of dhh should be the right one, but a bit old (last commit in 2007)

do you have any good experience with one of the 68 fork with rails 3? (rails/auto_complete/network)

thanks

First result on google and incredibly easy to get up and running. May require a bit of DIY and elbow grease but I found it to be minimally invasive...

Rails3-jquery-autocomplete is the best plugin to date :

It has a good documentation on github, it can get you up & running in a few minutes.
