Ok - I might be complicating too much. Heres how I would do it with c++, not 100% sure what approach should I take with rails on the database/model level.
If I want to have generic data-storage model Vehicle (which will hold information the same information for all the vehicles - car, boat, etc.) class vehicle holds: color, max-speed, .. class car: color, max-speed, number of seats, .. class boat: color, max-speed, ... with some boat-specific columns I'd just derive car from vehicle and use car-specific data columns because similar operations will be called on it as on boat model. As far as I understand RoR approach: if I have a lot of duplicated code in my application, there must be some better solution for my problem. What do you think?
