Hi again... :-)

I'm still working on RoR


right now i'm fighting against relationship.


I generated 3 scaffolds
car
wheel
engine


all the 3 CRUD works and now in the database I've many engines , many
wheel and many cars.

I want to correlate this object but how do it ?


I must say that car has_one engine and engine belongs_to car
(every car can have only one engine)

or i must write  that engine has_many cars and car belongs_to engine
(one engine is used on many different car)


or I need to create a new scaffold like road_ready_car which has_one
engine , has_one car and has_many wheels

????
