I have also attached the image so that you can look at the model itself

Also I am attaching you the created model ComicBook

 C:\Ruby\joker\chapter3>ruby script/generate model ComicBook
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/comic_book.rb
      create  test/unit/comic_book_test.rb
      create  test/fixtures/comic_books.yml
      create  db/migrate
      create  db/migrate/20100923101842_create_comic_books.rb

The environment I am working is

Ruby version    1.8.7 (i386-mingw32)
RubyGems version    1.3.7
Rack version    1.1
Rails version   2.3.8
Active Record version   2.3.8
Active Resource version 2.3.8
Action Mailer version   2.3.8
Active Support version  2.3.8
Application root    C:/Ruby/joker/chapter3
Environment development
Database adapter    mysql
Database schema version 20100923101842

Looking forward for your help

Thank You

Answer 1

Methods self.up and self.down must be in the migration(db/migrate/20100923101842_create_comic_books.rb)

Clean class of the CookBook model must look like this:

class CookBook < ActiveRedord::Base
end

Last 'end' missing in your code (models/comic_book.rb)
