Check if OneToOneField is None in Django

Question

I have two models like this:

class Type1Profile(models.Model):
    user = models.OneToOneField(User, unique=True)
    ...


class Type2Profile(models.Model):
            


        

Answer 1

Use select_related!

>>> user = User.objects.select_related('type1profile').get(pk=111)
>>> user.type1profile
None
