Comment:

 If you want to use `Derived.base` as your inheritance parent link you have
 to
 
[https://docs.djangoproject.com/en/2.2/ref/models/fields/#django.db.models.OneToOneField.parent_link
 mark it accordingly].

 Right now your table `Derived` model has two o2o fields pointing at
 `Base`; the explicit one you defined and the implicit parent link
 `base_ptr`. When you try to create your `Derived` object in `test_bug`
 it's the `base_ptr.v` field value that is missing.

 Adding `parent_link=True` to your `Derived.base` field should address your
 issue.

 Closing per TicketClosingReasons/UseSupportChannels.
