Chapter 7 of the Ruby on Rails Tutorial book
Feb 19, 2010 • posted by Michael Hartl
Chapter 7 is out. It uses Rails 2.3.5 as before, and I'll keep using Rails 2.3 until at least a Rails 3.0 release candidate (RC) is available, but I have got a nice Rails 3 beta setup running so you can expect an updated tutorial in a very timely manner. :-)
