Root Cause

pytest-django blocks DB access by default to keep tests fast. Any ORM query in a test without the django_db marker or db fixture raises this error.

generic

中文

pytest-django 默认阻止数据库访问以保持测试快速。任何未带 django_db 标记或 db fixture 的 ORM 查询都会引发此错误。

Workarounds

  1. 98% success 
    import pytest

@pytest.mark.django_db
def test_user_count():
    from myapp.models import User
    assert User.objects.count() == 0
  2. 95% success 
    def test_user_count(db):
    from myapp.models import User
    assert User.objects.count() == 0

Dead Ends

Common approaches that don't work:

  1. 85% fail

    That variable is for async ORM access, not for pytest-django's DB access guard.

  2. 80% fail

    Django is already set up; the guard is enforced by pytest-django at the connection level.
