I have a simple test model defined:
class Friend(models.Model):
name = models.CharField(max_length=120)
class Person(models.Model):
name = models.CharField(max_length=120)
friend = models.OneToOneField(Friend)
Here is a sample of usage, and obviously I am doing something wrong...
>>> p = mymodels.Person()
>>> p.name="John Smith"
>>> f = mymodels.Friend()
>>> f.name = "John Q. Smith"
>>> p.friend = f
>>> p.save()
Traceback (most recent call last):
File "<console>", line 1, in <module>

168, in execute
return Database.Cursor.execute(self, query, params)
IntegrityError: polls_person.friend_id may not be NULL
So then I try the following:
>>> p.friend.save()
>>> p.save()
And get the same error?
Any help would be appreciated.
Sincerely,
Dudley
