You don't actually say what the problem is. What happens when you save
an object using the code above?
The main problem that i can see with your code is not with save()
particularly, but with the way you're accessing the related values.
'self.responsible' is a ForeignKey, so using it as the lookup value
compared to a 'name' field is not likely to work.
The much easier and more obvious way is to do this:
if not self.responsible:
self.supervisor = self.byline.supervisor
else:
self.supervisor = self.responsible.supervisor
