That is very strange... I recreated this on my development system and it
worked fine. I looked for Django bugs, but haven't found any related to
this issue. To be clear, the table n_nics_groups definitely exists in the
same database as n_test_staff, right? It does in mine because I used python
manage.py syncdb to create them from the models. If so, maybe we should try
to create a raw() query to see if the system has a bug creating the query.
This should be similar:
form = StaffForm(instance = Staff.objects.raw("SELECT s.*, g.n_group_name
FROM n_test_staff s LEFT JOIN n_nics_groups g ON(g.n_group_number =
s.nics_group) WHERE s.username = 'tsamuel'))
If that throws an error, we may have a problem in the DB layer.
Thanks,
Furbee
