Comment (by tobias):
verified that WITHOUT inheritance this works OK:
{{{
class Order(models.Model):
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey()
status = models.CharField(max_length=10, default='ordered')
class Visitor(models.Model): # DOES NOT have parent model
order = generic.GenericRelation(Order)
}}}
{{{
SELECT COUNT(*)
FROM "testapp_visitor"
INNER JOIN "testapp_order" ON ("testapp_visitor"."id" =
"testapp_order"."object_id")
WHERE ("testapp_order"."status" = E\'ordered\' AND
"testapp_order"."content_type_id" = 9 )
}}}
