I am getting the following warning:
DEPRECATION WARNING: observer is deprecated and will be removed from Rails 2.0 See http://www.rubyonrails.org/deprecation for details.
And I would like to know how do I have to replace the ActiveRecord::Observer class. Nowadays, I am using Ruby 1.8.6, do I have to change it for the 2.0 version?
I have done a small research, but found almost nothing. On the http://www.rubyonrails.org/deprecation there is nothing about observer.
Then,I have read somewhere is that "What's deprecated is calling 'observer' from a controller. Instead, you need to set it in your config/environment.rb file: config.active_record.observers = :user_observer"
Is it correct? Otherwise what I should change?
Thank you for your help,
