'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)
    })

我做错了什么

Answer 1

Token.objects.create returns 一个元组（实例，令牌）。所以为了获得令牌使用索引 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
})

Answer 3

发生此特定错误是因为 Token.objects.create returns 一个元组（实例、令牌）。只需使用第二个位置 [1] 而不是 former

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

'AuthToken' 类型的对象不可 JSON 序列化

Object of type 'AuthToken' is not JSON serializable
