出现错误：AttributeError：'dict'对象没有属性'usertype'

Question

当我尝试从对象中获取价值时，它给我错误AttributeError: 'dict' object has no attribute 'usertype'，我可以看到我正在获取正确的queryset结果，但无法从中获取值，我的queryset <QuerySet [{'usertype': 2}]> ，这是我的完整代码，任何人都可以帮助我解决其中的问题吗？

class Login(APIView):
    permission_classes = (AllowAny,)

    def post(self, request):
        username = request.data.get("username")
        password = request.data.get("password")
        if username is None or password is None:
            return Response({'success': False, 'error': 'Please provide both username and password'},
                            status=HTTP_400_BAD_REQUEST)
        user = authenticate(username=username, password=password)
        # return Response({'success': True, 'user': user},status=HTTP_200_OK)
        if not user:
            return Response({'success': False, 'error': 'Invalid Credentials'},
                            status=HTTP_400_BAD_REQUEST)
        access_token, refresh_token = utils.generate_tokens(user)


        user_profile = UserProfile.objects.filter(user_id=user.id).values('usertype')

        print(user_profile[0].usertype)
