Saving & Retrieving Ranges

I would like to be able to save a set of age brackets as a range and have it treated as a Ruby range when retrieved from the database. I’ve done quite a bit of searching (maybe my Google-fu just sucks) but haven’t had any luck in getting to an answer. Anyone have any thoughts on doing this or should I simply save the minimum / maximum and roll my own range-like methods?

You could use serialize

class Person

serialize :age_range

end

teenager = Person.create(:age_range => 13…19)

But be aware that the actual field in the table will be a YAML-ized representation as a string.
