我正在尝试运行 pytest 并收到此错误:RuntimeError: Database access not allowed, use the "django_db" mark, or the "db" or "transactional_db" fixtures to enable it.
我在 test_models.py 中有以下测试,用于检查 uuid 是否已添加到用户中(它在自动添加中):
import pytest
from backendapps.core.models import User
pytestmark = pytest.mark.django_db
class TestUserModel():
user = User.objects.create()
assert user.uuid is not None
我在根级别还有一个名为 conftest.py 的 fixture 文件。import pytest
from backendapps.core.models import Org, User
@pytest.fixture(autouse=True)
def enable_db_access(db):
pass
然后我在根级别也有这个 pytest.ini :[pytest]
testpaths = backendapps
addopts = --ds=config.settings.local --reuse-db --create-db
python_files = tests.py test_*.py *_tests.py```
我的测试数据库设置为: 'TEST': {
'NAME': 'project_test_db',
},
通过其他帖子,以下是我采取的调试步骤:pytestmark = pytest.mark.django_db
line - 我有这个 关于尝试什么或如何获得更清晰的错误的任何想法?

我猜这个错误是由于您试图直接在测试对象上创建用户。因此,代码将在设置数据库之前执行,因此会出现错误。
您可以尝试在测试方法中创建用户:
class TestUserModel:
def test_user_uuid_is_not_none(self):
user = User.objects.create()
assert user.uuid is not None
或者你可以简单地运行一个测试功能def test_user_uuid_is_not_none(self):
user = User.objects.create()
assert user.uuid is not None
如果您需要在测试中多次访问用户,请创建一个装置并在测试中使用它:[conftest.py]
@pytest.fixture
def user() -> settings.AUTH_USER_MODEL:
# return the UserFactory (factoryboy)
return UserFactory()
[test_models.py]
import pytest
from django.contrib.auth import get_user_model
pytestmark = pytest.mark.django_db
User = get_user_model()
class TestUserModel:
def test_user_uuid_is_not_none(self, user: User):
assert user.uuid is not None
关于django - RuntimeError : Database access not allowed, 使用 "django_db"标记,或 "db"或 "transactional_db"设备来启用它,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/63717925/
