This has nothing to do with your question, but are you sure your data model is right ? The owner foreign key in Ipkunde means that a Person has one or more Ipkunde, and the uremip foreign key in Person means that a Ipkunde has one or more Persons. Seems like you want a many to many relationship here (which by the would solve your problem). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: models and forward declarations
Just found out that ForeignKeyField also accepts the model *name* instead of the model itself. Might solve the problem if this really works out :-) Michael --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I found your thread at: http://groups.google.com/group/django-users/browse_thread/thread/71fc72ab1f547d3/4d0dbfdfd9dc8a05?q=%22forward+references%22=2#4d0dbfdfd9dc8a05 No, unfortunately, this doesn't work within the class itself but only within a def. I tried, just to make sure, this: class Person(models.Model): from django_pop.email_admin.models import Ipkunde ... uremip = models.ForeignKey(Ipkunde, db_column='ipkunde') class Ipkunde(models.Model): ... owner = models.ForeignKey(Owner, db_column='person') Result: Traceback (most recent call last): File "", line 1, in ? File "/home/mir/src/django_pop/../django_pop/email_admin/models.py", line 663, in ? class Person(models.Model): File "/home/mir/src/django_pop/../django_pop/email_admin/models.py", line 664, in Person from django_pop.email_admin.models import Ipkunde ImportError: cannot import name Ipkunde There's also another thread, about my problem, at http://groups.google.com/group/django-users/browse_thread/thread/24a996f32de9c112/35e4a288a7337db9#35e4a288a7337db9 but there's only someone else stating the same problem and no solution :-( Michael --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
