JSON 직렬화 불가능한 django REST 프레임웍

Question

안녕하세요, 'MyUser'유형의 객체가 JSON 직렬 가능하지 않습니다. 동일한 문제가있는 많은 게시물에서 Checke하지만 아무 것도 내 코드 작업을하지 못합니다.

누군가 나를 도와 드릴까요? 내보기에

:

class TeamChartData(APIView): 
    queryset = MyUser.objects.all() 
    serializer_class = MyUserSerializer 
    permission_classes = [] 
    http_method_names = ['get',] 


    def get_serializer_class(self): 
     return self.serializer_class 


    def get(self, request, format=None, *args, **kwargs): 
     chunk_team = get_chunk_team(self) 
     data = { 
      "chunk_team":chunk_team 
     } 
     return Response(data) 

def get_chunk_team(self, format=None, *args, **kwargs): 
    current_team_member = Project.objects.get(id = self.kwargs['pk']).team_id.members.all() 
    print(current_team_member) 

    return current_team_member

해당보기는 다음과 같습니다.

class TeamChartData(APIView): 
    queryset = MyUser.objects.all() 
    serializer_class = MyUserSerializer 
    permission_classes = [] 
    http_method_names = ['get',] 


    def get_serializer_class(self): 
     return self.serializer_class 


    def get(self, request, format=None, *args, **kwargs): 
     chunk_team = get_chunk_team(self) 
     chunk_team = MyUserSerializer(chunk_team).data #included line 
     data = { 
      "chunk_team":chunk_team 
     } 
     return Response(data) 

def get_chunk_team(self, format=None, *args, **kwargs): 
    current_team_member = Project.objects.get(id = self.kwargs['pk']).team_id.members.all() 
    print(current_team_member) 

    return current_team_member
