Root Cause

pytest-django blocks DB access by default to keep tests fast and isolated. Any ORM call in a test without @pytest.mark.django_db or the db fixture raises this failure.

generic

中文

pytest-django 默认阻止数据库访问，以保持测试快速且隔离。任何没有 @pytest.mark.django_db 或 db fixture 的 ORM 调用都会引发此失败。

Workarounds

  1. 97% success 
    import pytest

@pytest.mark.django_db
def test_create_user():
    User.objects.create(email='[email protected]')
    assert User.objects.count() == 1
  2. 96% success 
    def test_create_user(db):
    User.objects.create(email='[email protected]')
    assert User.objects.count() == 1

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The block is enforced by pytest-django's plugin, not by the database backend; the failure occurs before any connection is attempted.

  2. 80% fail

    NameError: name 'pytest' is not defined, or the mark is silently ignored if imported incorrectly.
