在邮递员上使用 POST 时，它会返回 TypeError：列表索引必须是整数或切片，而不是 str。如果我从客户端 POST(react) 我得到一个网络错误 'int' object is not iterable

PostMan POST:
    [
 {
    "time": "2019-12-12","user": 1,"title": "Test123","description": "Nice!","photo": "http://localhost:8000/asd","activity": [{"name": "hike"},{"name": "swimming"}]
}

Django 查看位置创建

 def get_queryset(self):
        LOCATIOn = LOCATIOn.objects.all()
        return LOCATIOn

    def create(self,request):
        """Handle LOCATIOn operations for categorIEs"""
        

        data = request.data
        user = VacaUser.objects.get(user=request.auth.user)
        

        new_LOCATIOn = LOCATIOn.objects.create(
            user=user,photo=data["photo"]
        )

        new_LOCATIOn.save()

        for activity in data["activity"]:
            activity_obj = Activity.objects.get(activity_name=activitY["activity"])
            new_LOCATIOn.activity.add(activity_obj)

        serializer = LOCATIOnserializer(new_LOCATIOn,context={'request': request})

        try:
            return Response(serializer.data)
        except ValIDationError as ex:
            return Response({"reason": ex.messagE},status=status.http_400_BAD_requEST)

这就是数据=

    [{'time': '2019-12-12','user': 1,'title': 'Test123','description': 'Nice!','photo': 'http://localhost:8000/asd',> 'activity': [{'name': 'hike'},{'name': 'swimming'}]}]
