在导轨中创建新对象时出错

我在导轨中遇到此错误，当我尝试为模型创建对象时。我工作在Windows 7在导轨中创建新对象时出错

C:\Ruby\joker\chapter3>ruby script/console 
Loading development environment (Rails 2.3.8) 
>> mycb = ComicBook.new

我还附上图像，这样你可以看看模型本身

而且我附上你创建的模型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

我工作的环境是

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

期待您的帮助

谢谢

方法self.up和self.down必须在迁移（DB /迁移/ 20100923101842_create_comic_books.rb）

清洁类菜谱模型必须是什么样子这样的：

class CookBook < ActiveRedord::Base 
end
