Ruby Forum Rails deployment > NoMethodError (undefined method `model' for ContactControlle

First rails application!

I can not figure out all the details of how the method 'model' is
defined !

The error occurs when processing the statement:
model :contact
in the file app/controllers/contact_controller.rb

following the commands:
rails AddressBook
cd AddressBook
ruby script/generate model contact
ruby script/generate controller contact
... fix the db to use mysql .. where the database table is created as
per..
http://www-128.ibm.com/developerworks/linux/library/l-rubyrails/

Error happens when I connect: http://...:8000/contact

------------------------------------
--> file: app/controllers/contact_controller.rb
class ContactController < ApplicationController
  model :contact
  scaffold :contact
end

--> file: app/models/contact.rb
class Contact < ActiveRecord::Base
end

I think the rails forum is more appropriate for this message and I have 
posted a copy of the message there.  Regards, Keith Tice
