Hi there, Are you sure that you want to denormalize your schema like that ? I now this is a totally different issue and question but in this case do you really need to perform this operation ? Have considered the problems that this approach will bring?
Imagine this simple use case: If one changes the country_of _orign of the Producer that wont reflect on the Car instance! I can see some utility for this use but in any case I would review my requirements. Cheers, N.
