Using: Django 1.10, python 3.5 and django-positions 0.5.4
Example model:
import uuid
class Example(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True)
parent = models.ForeignKey(SomeOtherModel)
position = PositionField(null=True, blank=True, collection='parent')
When saving this django will first try an update call because the primary key is already set, which will call the pre_save on the position field with add=False, which will then throw the DoesNotExist error because it tries to load the model from the database which doesn't exist yet.
Maybe it should have a try except in the pre_save to make sure it won't blow up.
