serializable_attribute_names() public

To replicate the behavior in ActiveRecord#attributes, :except takes precedence over :only. If :only is not set for a N level model but is set for the N+1 level models, then because :except is set to a default value, the second level model can have both :except and :only set. So if :only is set, always delete :except.
