`alias_method_chain': undefined method `find' for class `ActiveRecord::Base' (NameError)

I can't seem to be able to override the :find method in the model base class, for example, in /lib/usermonitor.rb:

module ActiveRecord   module UserMonitor     def self.included(base)       base.class_eval do         alias_method_chain :find, :user

        def current_site           Thread.current[:user]         end       end     end     def find_with_user(*args)       ...     end   end end

I got this error:

`alias_method_chain': undefined method `find' for class `ActiveRecord::Base' (NameError)

However, overriding :create and :update methods work fine. Why?
