[Django]-Django Rest Framework Without Database

✅

The actual cause of the problem is that DRF trys to add a user attribute to the request. Briefly mentioned in the documentation, the mechanism is as follows:

How authentication is determined

If no class authenticates, request.user will be set to an instance of
django.contrib.auth.models.AnonymousUser

So it needed the django.contrib.auth application to run correctly, consequently django.contrib.auth requires a working configuration of Database to be able to perform.

The solution to this problem is to set the settings UNAUTHENTICATED_USER property to None.

Configuration will be like this after the changes:

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [],
    'DEFAULT_PERMISSION_CLASSES': [],
    'UNAUTHENTICATED_USER': None,
}

If you are really forced to use a database but you don’t want to, you can use :memory: with the SQLite backend, like this:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': ':memory:',
    }
}

This uses an in-memory database, so that your filesystem won’t be touched.

Because memory is volatile, you might need to run migrations automatically every time your web app starts.

You don’t have any option. DATABASES dict should be in settings.py. You can use this:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

[not tested] maybe you could use a dummy backend. I see there’s one from django:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.dummy',
    }
}
