I've just started using DBIC in catalyst, and the intro docs show you ho 
to do just what you need right from the start.

IMHO this is a good reason (among others that anybody here will be glad 
to show you :-) to change from cdbi models to dbic ones.

Unfortunately, migrating an app (even a simple one) from cdbi to dbic 
(natively, i.e. without using dbic's compatibility layer) is not so 
easy... (well, at least not for the ancillary features I've added to my 
cdbi model classes :-)
