Django Foreign Key reference object or uuid? Correct way here

Trying to make sense of some Django

I have something like(left out other fields): 

class Reservation(Model):
   extendedReservation = models.ForeignKey('Reservation', default=None, blank=True, null=True)

Does it expect a Reservation object or a Reservation ID when creating reserrvation with extendedReservation not null/none?

So should I do(reference the object or the uuid?):

    reservation = Reservation.objects.create(user=forUser, resource=resource, timeFrom=timeFrom, timeTo=timeTo, extendedReservation=extendedReservation)

or 

reservation = Reservation.objects.create(user=forUser, resource=resource, timeFrom=timeFrom, timeTo=timeTo, extendedReservation=extendedReservation.uuid)

You should be able use both variants to pass a value for a foreign key, if your uuid field is a model's primary key.
