Read the replies about scaffolding basically you’ll need to install the  
scaffolding gem:

From a command prompt in your app root:

ruby script/plugin install scaffolding

or install a previous version of rails (if you are working through a  
book it’s probably a good idea to use the same version it uses)

gem install rails -v=“1.2.3”

For simplicities sake probably just uninstall your current rails version  
(gem uninstall rails) first then install the older version; that way  
you’ll know the rails commands are running the correct version.

Cheers
