I wanted a slightly more generic to_xml solution for Recipe #66 so I came up with this:

  def to_xml(options = {})
    options[:only] = self.class.column_names - self.class.attr_protected.to_a

This will only work if you are defining protected attributes but, I’ll leave the accessible case as an exercise for the reader ;)
