You cannot expect DM to do this on your behalf nor should you. DM resources can parse date strings as properties of course, but you need to massage your params to get the date into an acceptable format. My point was that this would be a responsibility of your web framework or front-end not DM.
A similar example of this is the DateHelper.date_select in rails which does some hocus pocus with param suffixes and Date::civil to get the values from the three options into a proper date that AR can understand.
