根因分析

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。

English

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.

解决方案

  1. 98% 成功率 
    import pytest

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

无效尝试

常见但无效的做法:

  1. 85% 失败

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

  2. 80% 失败

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