'AuthToken'类型的对象不可JSON序列化

Question

创建令牌时出现上述错误，代码如下：

from rest_framework import generics, permissions
from rest_framework.response import Response 
from knox.models import AuthToken
from .serializers import UserSerializer, RegisterSerializer

class RegisterAPI(generics.GenericAPIView):
    serializer_class = RegisterSerializer

def post(self, request, *args, **kwargs):
    serializer = self.get_serializer(data=request.data)
    serializer.is_valid(raise_exception=True)
    user = serializer.save()
    return Response({
        "user": UserSerializer(user, context=self.get_serializer_context()).data,
        "token": AuthToken.objects.create(user)
    })

我在这里做错了什么

Answer 1

Token.objects.create返回一个元组（实例，令牌）。因此，为了获得令牌，请使用索引1

"token": AuthToken.objects.create(user)[1]

Answer 2

更好的方法是在python中使用此方法

_, token = AuthToken.objects.create(user)
return Response({
    "user": UserSerializer(user, context=self.get_serializer_context()).data,
    "token": token
})
