Validation is skipped.
Callbacks are invoked.
updated_at/updated_on column is updated if that column is available.
Updates all the attributes that are dirty in this object.

This method raises an ActiveRecord::ActiveRecordError if the attribute is marked as readonly.

If any of the before_* callbacks throws :abort the action is cancelled and #update_attribute! raises ActiveRecord::RecordNotSaved. See ActiveRecord::Callbacks for further details.
