About Default Auto Field
If you are developing a third-party Django app that is providing any models, always set the default_auto_field in the apps.py.
class MyAppConfig(AppConfig):
default_auto_field = "django.db.models.BigAutoField"
# or default_auto_field = "django.db.models.AutoField"
Otherwise, the individual DEFAULT_AUTO_FIELD setting at a project level will trigger database migration creation in your app whenever it doesn't match your apps' migrations and a developer runs makemigrations.
