Good morning Martin I wrote this Saturday night, it uses Moose as both HTML::FormHandler and Catalyst do... as long as result_source->columns_info gives you what I think, it should work... beware I only wrote on quick test :)
https://github.com/ThisUsedToBeAnEmail/HTML-FormHandler-Role-Default/blob/master/lib/HTML/FormHandler/Role/Default.pm If you're adamant on having this logic in your schema I would looking into just writing a new_with_defaults method where you just loop through the Results column info build a hash and then return new_result(%defaults).
