I don't know if it's clever or stupid, but this is what I have done in a
similar situation:
#-------------------------------------------------
class Item(models.Model):
....
typecode = models.CharField(max_length=30, editable=False)
def save(self, force_insert=False, force_update=False):
self.typecode = self.__class__.__name__.lower()
super(Item, self).save(force_insert, force_update)
def get_related(self):
return
self.__class__.__dict__[self.typecode].related.model.objects.get(id=self.id)
class SubItem(Item):
....
#-------------------------------------------------
If called from an Item instance, 'get_related' will return the related
SubItem instance. In your case, you would first get the 'restaurant',
then call it's 'get_workforce'. Still working on it, so there may be
unforseen issues.
