thanks - I've tried it both ways and with __str__ get the error __str__ returned non-string (type NoneType).
the top-level error dump is Request Method: GET Request URL: http://localhost:8000/admin/papers_admin/paper/35/ Exception Type: TypeError Exception Value: __str__ returned non-string (type NoneType) Exception Location: C:\Python25\lib\site-packages\django\db\models \fields\__init__.py in get_choices, line 302 all the models where I apply __str__ are of the form class LuPaperContentRegion(models.Model): paper_content_region = models.CharField(maxlength=150) def __str__(self): return self.paper_content_region class Meta: db_table='lu_paper_content_region' Now, I am a little confused as to the general set-up for attaching a list to the FK model as Country = models.ForeignKey(LuCountry) since this would be a link to the LuCountry table by the ID and my expectation is this might display the ID in the linked table, not a string so perhaps this may be the source of the problem -- but that is just a guess. Thanks for your response - hopefully there is a simple thing I am not getting. On Apr 13, 8:35 pm, Michael <[EMAIL PROTECTED]> wrote: > Try changing __unicode__ to __str__.
