Override ActiveRecord:Base.destroy

Dear rails developpers Im build a new adapter (mongo)

I need to override this:

      # Deletes the record in the database and freezes this instance
to reflect that no changes should
      # be made (since they can't be persisted).
      def destroy
        unless new_record?
            "DELETE FROM #{self.class.quoted_table_name} " +
            "WHERE #{connection.quote_column_name
(self.class.primary_key)} = #{quoted_id}",
            "#{self.class.name} Destroy"


I tried (As I see on the web) to override it with
destroy_without_callbacks, but didn't work. Any suggestion?
