Best rating plugin

Hi,

I just joined rails and i need to create a website that rates
products. Been googling but the rating plugins are either outdated or
obsolete. Can someone point me to a working tutorial for a rating
plugin?

Regards
Shawn

I am new to Ruby on Rails and downloaded the Instant Rails package to
start
and I used this tutorial:
http://www.tanguay.info/web/tutorial.php?idCode=rubyOnRails

The tutorial is preatty good and easy but I got stuck on this section
below, could anyone help me? THANK YOU. This is the link that will
bring
you to the same place I got stuck, is about “Make Mmebers Page”
http://www.tanguay.info/web/tutorial.php?idCode=rubyOnRails&sectionIdCode=makeMembersPage

I done everything by the tutorial but can`t get this done, how do I
write
in there?
