Description
I have a situation where I need to load huge db fixture which is created by a function. The fixture is needed in all api tests. So I made a session fixture at conftest.py which would do it. But the problem is pytest throws following exception even though I have marked django_db:
E Failed: Database access not allowed, use the "django_db" mark to enable it.
Below is my code snippet.
from permission.helpers import update_permissions
pytestmark = [
pytest.mark.django_db(transaction = True),]
@pytest.fixture(scope="session", autouse = True)
def permission(request):
load_time_consuming_db_fixture()

Research direction
Start with the session-scoped fixture in conftest.py and the pytest.mark.django_db(transaction=True) declaration. Reproduce the database-access failure in the API tests, then determine the supported session-fixture setup so the generated database fixture loads successfully without the exception.
