Comment (by gordyt):
I just uploaded a self-contained ''models.py'' file at the request of
Karen T. from [[http://groups.google.com/group/django-
users/browse_thread/thread/e2ed78ae41011b75/ this thread]]. The comments
at the top of the file show the error message. It is possibly related to
this ticket and, if so, is very easy to reproduce because you don't need
to write any views, etc.
Just drop this into an app and file up the admin interface. Add a Book
and (using the inline admin interface), add one or more Authors. This
should save with no errors. Then, click on the Book entry in the admin
interface. This should display just fine and also show the associated
Author(s).
You can make a change or not, just click Save again and you should get an
error message.
You will notice that both the Book and the Author models are using a
custom primary key - a UUIDField that came straight out of the django-
extensions project.
This error seems to occur only with using a custom primary key with an
inline object. So if Book and Author each have separate admin pages, no
errors occur.
Hope this helps!

P.S. - At the top of the thread that I referenced I referred to a
customized version of the UUIDField -- one that uses native uuid database
types if the backend supports it. To eliminate the possibility that my
customized UUIDField was causing the problem, I replicated the issue using
an unmodified version of the UUIDField and that is what is included in the
models.py file.
