hm, what i wrote vanished, but empty and blank strings shouldn't pass that validation, as the above shows.

This behaviour is controlled by the
:allow_niloption for the format validator. The option defaults to true, which is why empty strings pass the validator (they don't even touch the regex). I would suggest combining the validator with avalidates_presentor setting:allow_nil => falsefor the format validator. I'm marking the ticket n/a, but if you think the default behaviour should change, please raise it for discussion on the mailing list or on IRC.
