python - create() 接受 1 个位置参数，但给出了 3 个

Question

这是我第一次使用 django 休息框架创建 api 休息，我到了注册用户并使用 token 记录它们的地步，我的问题是我可以使用 Django 的默认用户完成所有这些操作，在我的情况下，我需要一个具有另一个名为 is_technical (is_technical) 的 bool 变量的个性化用户。我将放置到目前为止我所做的相关代码，但要清楚的是，我想制作一个带有 DRF 和一对一链接的登录系统...

models.py(我尝试多次重写创建方法，但不起作用)

class Usuario(models.Model):
    user = models.OneToOneField(User, on_delete = models.CASCADE)
    es_tecnico = models.BooleanField(name = 'es_tecnico', default = False, blank = True)

View .py

class UsuarioViewSet(viewsets.ModelViewSet):
    lookup_field = 'id'
    serializer_class = UsuarioSerializer
    queryset = Usuario.objects.all().filter(es_tecnico = False)


class TecnicoViewSet(viewsets.ModelViewSet):
    lookup_field = 'id'
    serializer_class = UsuarioSerializer
    queryset = Usuario.objects.all().filter(es_tecnico = True)


class PedidoViewSet(viewsets.ModelViewSet):
    lookup_field = 'id'
    serializer_class = PedidoSerializer
    queryset = Pedido.objects.all()


# class PedidoMiUsuarioSet(viewsets.ModelViewSet):
#     serializer_class = PedidoSerializer
#     queryset = Pedido.objects.all().order_by('-id').filter(autor = "3")

class Registrar(mixins.CreateModelMixin, viewsets.GenericViewSet):
    serializer_class = UsuarioSerializer

    def create(self, request, *args, **kwargs):
        #  Creando un nuevo usuario
        username = request.POST.get('user.username')
        password = request.POST.get('user.password')
        es_tecnico = request.POST.get('user.es_tecnico')
        print(username)

        user = User.objects.create_user(username, password)
        user.save()

        token = Token.objects.create(user=user)

        # usuario = Usuario.objects.create(user, es_tecnico)
        # usuario.save()

        return Response({'detail': 'El usuario fue creado con el token: ' + token.key})


class LoginView(mixins.CreateModelMixin, viewsets.GenericViewSet):
    serializer_class = LoginSerializer

    def create(self, request):
        serializer = LoginSerializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.validated_data["usuario"]
        django_login(request, user)
        token, created = Token.objects.get_or_create(user=user)
        return Response({"token": token.key}, status=200)


class LogoutView(mixins.CreateModelMixin, viewsets.GenericViewSet):
    authentication_classes = (TokenAuthentication, )

    def create(self, request):
        django_logout(request)
        return Response(status=204)
    enter code here

如果您需要更多信息或代码，请告诉我，我会尽快回复。或者，如果您推荐另一个与“自定义用户”一起使用的框架，我将不胜感激

Answer 1

改变

usuario = Usuario.objects.create(user, es_tecnico)

至

usuario = Usuario.objects.create(user=user, es_tecnico=es_tecnico)

在/misitio/pedidos/views.py中，第58行
