DataError on get_or_create with nullable fields

[mccc]

(this is mostly copied/pasted from my comment on an eight-years-old issue here)

I cannot get the get_or_create operation to create non-existing object with nullable field, getting a `DataError: integer out of range` error.

The query goes like so: `Test.objects.get_or_create(**{u'device_preference__isnull': True, u'test_type': u'TextTest', u'master_id': 1234, u'testset_id__isnull': True})` where `device_preference` is a nullable PositiveIntegerField and `testset_id` is a ForeignKey.

Attached traceback shows that the issue happens on creation, I believe.

I have not reopened the issue, just because, but I'd welcome any possible comment.

Thank you.

Well turns out it was actually the `master_id` foreign key that was being set to garbage, hence the DataError;

everything besides me is working as intended.
