Comment:
The `PizzeriaBar` model is inheriting the `restaurant_ptr` field from both
`Pizzeria` and `Bar`, so you need to specify the parent link field on at
least one of them, per
https://docs.djangoproject.com/en/dev/topics/db/models/#specifying-the-
parent-link-field. This gets a little complicated if you are creating this
child model and overriding these field names at a later date than the
parent since you are changing the field name, it is going to require using
the `db_column` arg on the field or more complex migrations.
This seems to me to have a lot of caveats to be provided as an example in
the docs; however, here is a PR that updates the existing example to be
working.
