Python 创建&；序列化程序中的返回标记

当前在我的注册视图中返回令牌时遇到困难

如何修复此问题，以便UserSerializer的create可以返回令牌和用户名

View.py

@permission_classes([AllowAny])
class UserCreate(generics.CreateAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer

序列化程序.py

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('username', 'password')
        extra_kwargs = {'password': {'write_only': True}}

    def create(self, validated_data):
        password = validated_data.pop('password')
        user = User(**validated_data)
        user.set_password(password)
        user.save()
        token, _ = Token.objects.get_or_create(user=user)
        return Response(
            {
                'username': validated_data['username'],
                'token': token.key,
            },
            status=HTTP_200_OK
        )

错误

最终将其放入序列化程序：

class UserCreate(generics.CreateAPIView):
    queryset = User.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)
        token, created = Token.objects.get_or_create(user=serializer.instance)
        return Response({'token': token.key, 'username': serializer.instance.username}, status=HTTP_201_CREATED)```

错误显示数据中缺少

username

。这是我的请求：

httpposthttp://127.0.0.1:8000/account/register username='test37'password='password'

将

打印（已验证的\u数据）

放入序列化程序中，查看是否包含所有必需的字段。{“username”：“test40”}

class UserCreate(generics.CreateAPIView):
    queryset = User.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)
        token, created = Token.objects.get_or_create(user=serializer.instance)
        return Response({'token': token.key, 'username': serializer.instance.username}, status=HTTP_201_CREATED)```
