8648	Admin ignores to_field on ForeignKey	Karen Tracey	nobody	"As reported here: http://groups.google.com/group/django-users/browse_thread/thread/47d31f56c1924cfa#

With current (I'm running [8661]) admin, for a model specified like so:

{{{
class Inventory(models.Model):
   barcode = models.PositiveIntegerField(unique=True)
   parent = models.ForeignKey('self', to_field='barcode', blank=True, null=True)
   name = models.CharField(blank=False, max_length=20)
   def __unicode__(self):
      return self.name
}}}

The admin treats 'parent' as though it refers to the pk field, not the barcode field.  

Old admin (0.96) handled this properly, that is it showed information for the related model that matched on the barcode field, not the pk field.
