python - 如何使用 pytest-django 为每个 session 只创建一次用户对象？

Question

首先，我厌倦了这个:

@pytest.mark.django_db
@pytest.fixture(scope='session')
def created_user(django_db_blocker):
    with django_db_blocker.unblock():
        return CustomUser.objects.create_user("User", "UserPassword")

def test_api_create(created_user):
    user = created_user()
    assert user is not None

但我收到了 UndefinedTable错误。所以用 @pytest.mark.django_db 标记我的灯具不知何故实际上并没有注册我的 Django DB。所以接下来我尝试将 db 对象直接传递给 fixture :

@pytest.fixture(scope='session')
def created_user(db, django_db_blocker):
    with django_db_blocker.unblock():
        return CustomUser.objects.create_user("User", "UserPassword")

def test_api_create(created_user):
    user = created_user()
    assert user is not None

但后来我得到了一个错误

ScopeMismatch: You tried to access the 'function' scoped fixture 'db' with a 'session' scoped request object, involved factories

所以最后，为了确认一切正常，我尝试了:

@pytest.fixture
def created_user(db, django_db_blocker):
    with django_db_blocker.unblock():
        return CustomUser.objects.create_user("User", "UserPassword")

def test_api_create(created_user):
    user = created_user()
    assert user is not None

这工作得很好，但现在每次设置或拆除我的函数时都会调用我的 create_user 函数。这里的解决方案是什么？

@hoefling 有答案，我需要通过 django_db_setup反而。

@pytest.fixture(scope='session')
def created_user(django_db_setup, django_db_blocker):
    with django_db_blocker.unblock():
        return CustomUser.objects.create_user("User", "UserPassword")
