Rails 3 observers

Rails Guides says: ...the UserObserver ... would be saved as app/models/user_observer.rb and registered in config/environment.rb this way: config.active_record.observers = :user_observer

But the observer registration above doesn't work because there is no 'config'. For now, I've put it in the config/environments/[APP_ENV].rb but that seems really sloppy and redundant.

What am I missing here?


If you are using rails 3 the configuration goes in the application.rb file in the config folder. Look at line 23.
