Saving without callbacks - any better way?

saving_without_callbacks.rb

module SavingWithoutCallbacks
  def save_without_callbacks
    raise "Only works for saved records" if new_record?
    updates = {}
    changes.each {|key, tuple| updates[key] = tuple.last}
    self.class.update_all(updates, {:id => self.id}, {:limit => 1})
  end
end

ActiveRecord::Base.send :include, SavingWithoutCallbacks

Turns out that ActiveRecord::Base objects already have a method called save_without_callbacks via an alias_method_chain on save/create/update/etc that's put there for adding callbacks to persistence methods (https://github.com/rails/rails/blob/v2.3.11/activerecord/lib/active_record/callbacks.rb#L223-225). Thanks to Bryce Kerley (@BonzoESC) for the answer.
