将 LoginBackEnd 模块导入 settings.py 时出错

Question

我只使用电话号码作为唯一的登录字段。 所以我正在尝试编写我的自定义后端身份验证。 在尝试导入 LoginBackend 模块时，出现以下错误。

配置身份验证后端时出错：

 File "C:\Users\UBITEK\AppData\Local\Programs\Python\Python38-32\lib\site-packages\django\conf\__init__.py", line 161, in __init__
    raise ImproperlyConfigured("The SECRET_KEY setting must not be empty.")
django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

@csrf_exempt
@api_view(["POST"])
@permission_classes((AllowAny,))
def logins(request):
    phone_number = request.data.get("phone_number")
    if phone_number is None:
        return Response({'error': 'Please provide your phone number'},
                        status=HTTP_400_BAD_REQUEST)
    user = authenticate(phone_number=phone_number)
    if not user:
        return Response({'error': 'Invalid Credentials'},
                        status=HTTP_404_NOT_FOUND)
    token, _ = Token.objects.get_or_create(user=user)
    return Response({'token': token.key},
                    status=HTTP_200_OK)

后端.py

from django.contrib.auth.backends import ModelBackend
from .models import User

class LoginBackend(ModelBackend):
    def authenticate(self, request, **kwargs):
        phone_number= kwargs['phone_number']
        user = User.objects.get(phone_number=phone_number)
        if user:
            return user
        else:
            return None

设置.py

from .backends import LoginBackend
from django.contrib.auth.backends import ModelBackend
AUTHENTICATION_BACKENDS = ['django.contrib.auth.backends.ModelBackend',
    'findr.backends.LoginBackend']

使这些东西正常工作所需要做的就是撤消 settings.py 中的导入语句。
