I think I must be doing something wrong... when a form returns params
to the controller, empty fields appear to be returned as blank, not
nil. so what's the point of an :allow_nil=>true setting on a
validation? it fails because blank is not the same as nil.
i would expect either returned empty fields to be nil, or :allow_nil
to really be :allow_blank. otherwise i have to do a search through
params every time i do a create/update to convert blank to nil.
totally unrailslike. someone straighten me out please...
thx - mike
