Django Rest Framework - 注册后返回用户ID和令牌

Question

我尝试注册用户并返回令牌和用户ID.这样做

from django.shortcuts import render
from rest_framework.response import Response
from rest_framework.authtoken.models import Token
from rest_framework import status
from django.contrib.auth import get_user_model

User = get_user_model()

class CreateUser(CreateAPIView):
    queryset = Profile.objects.all()
    serializer_class = UserSerializer

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        headers = self.get_success_headers(serializer.data)
        token, created = Token.objects.get_or_create(user=serializer.instance)
        user = User.objects.filter(user=serializer.instance)
        return Response({'token': token.key, 'id':user.id}, status=status.HTTP_201_CREATED, headers=headers)

我收到一个错误

Cannot resolve keyword "user" into field. Choices are: auth_token, date_joined, email, first_name, groups, id, is_active, is_staff, is_superuser, last_login, last_name, logentry, password, user_permissions, username

我究竟做错了什么 ？

Answer 1

错误就在于此

user = User.objects.filter(user=serializer.instance)

首先,user您的User模型上没有命名的字段.其次,您不需要对User模型进行过滤以获取创建的用户,因为您已经拥有了用户serializer.instance.所以,没有必要这条线.

如果你只是想要id,你可以使用它serializer.instance.id.
