I get an error message:

> NoMethodError (undefined method `model’ for ContactController:Class):

The error occurs when processing the statement:

> model :contact  
> in the file app/controllers/contact\_controller.rb (see below)

I built the application with the following commands:

> rails AddressBook  
> cd AddressBook  
> ruby script/generate model contact  
> ruby script/generate controller contact  
> … I fixed the db to use mysql … I created the needed database table  
> per…  
> [http://www-128.ibm.com/developerworks/linux/library/l-rubyrails/](http://www-128.ibm.com/developerworks/linux/library/l-rubyrails/)

The error happens when I connect: http://…:8000/contact

This is my first rails application!

I can not figure out all the details of how the method ‘model’ is  
defined and called from the controller!

## Thanks for any information.

→ file: app/controllers/contact\_controller.rb  
class ContactController \< ApplicationController  
model :contact  
scaffold :contact  
end

→ file: app/models/contact.rb  
class Contact \< ActiveRecord::Base  
end

That’s obsolete. You don’t need it anymore. I’d follow another  
tutorial if i were you, that one is 3 years old which is positively  
ancient for rails.
