Importing setting file directly
Using from django.conf import settings simplifies the code and makes it more maintainable.
It's preferable to use from django.conf import settings instead of importing the settings file directly.
Importing directly can trigger a race condition when your code imports settings before the app is ready.
Overriding settings in tests is simplified when using django.conf.settings as you can then use Django's modify_settings and django-pytest's settings fixture, which rely on the code using django.conf.settings.
So in practice, do this
from django.conf import settings
Instead of this
from example.config import settings
Are you affected? Check with
pip install django-doctor.
Configuring this check
Django Doctor will run this check by default. No configuration is needed but the check can be turned on/off using check code direct-import-settings in your pyproject.toml file.
