Since django insists on throwing a DoesNotExist rather than just returning a None from the far side of a null OneToOneField, I wrote this to have a sane way of getting those fields out without having to try/except all over in my code.

from django.core.exceptions import ObjectDoesNotExist

def get_onetoone_or_none(obj, attr):
    """ Instead of letting django throw and exception, return None when a OneToOneField is null """
    try:
        return getattr(obj, attr)
    except ObjectDoesNotExist:
        return None
