This is likely a mistake on my part. I'm not a Django expert, and I really struggle and grope when working with a relational database model. Possibly we should be generating ManyToManyField instead of ForeignKey? I'll take a look. But, since I suspect that you understand this better than I do, you might be better off if you figure out what code you think it should generate then either let me know or modify django/generatedssuper.py in the distribution yourself. If you have suggestions about the correct code to generate, please let me know. > > Look at the attachment - ZPWP element can have unbounded number of > PM elements, i.e. we have a relationship ZPWP(1) - (n)PM.

I do not understand relational database talk very well, but I think I understand what you mean here. Would replacing ForeignKey with ManyToManyField fix this? Or, do we have to put the ForeignKey at the other end? When I wrote that code, I wondered about that. I'll take another look. Maybe I'll learn something. > > Is it a correct situation or I don't understand it correctly? > > Thanks for any answer, > Piotr Kaczynski > > P.S.

But, answering your questions does take some Django expertise, so you are likely to get better answers to questions about Django models at django-user (http://groups.google.com/group/django-users). Either way, let me know what I can do to help out. And, like I say, I'll take another look at that code. - Dave -- Dave Kuhlman http://www.rexx.com/~dkuhlman ------------------------------------------------------------------------------ What Every C/C++ and Fortran developer Should Know!
