I read the following book this weekend

and do the exam it mentions, but there is a problem.

Q: NoMethodError (undefined method `scaffold’ for AdminController:Class):
A: my rails version is 2.3.2
the “scaffold” method was removed in Rails 2.0.
in order to resolve it , just run the following commands in the app directory
script/plugin install scaffolding
script/plugin install svn://errtheblog.com/svn/plugins/will_paginate

when u want to practice with the examples, just install the lower version
gem install rails –version 1.2.6 –include-dependencies
