Я работаю над проектом django, и у меня есть сообщение модели django:

 class Message(models.Model):
    content     = models.TextField(_('Content'))
    sender      = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='sent_dm', verbose_name=_("Sender"),on_delete=models.CASCADE)
    recipient   = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='received_dm', verbose_name=_("Recipient"),on_delete=models.CASCADE)
    sent_at     = models.DateTimeField(_("sent at"), null=True, blank=True)
  

views.py

 class MessageCreateView(APIView):
    queryset = Message.objects.all()
    serializer_class = MxCreateSerializer

    def get(self, request, format=None):
        serializer = MxCreateSerializer()
        return Response({'serializer':serializer})
        
    def post(self, request):
        sent_data   = request.data
        #print(sent_data)
        data_       = [elem for elem in sent_data.values()]
        sender      = data_[0]
        content     = data_[1]
        recipient   = data_[2]
        csrf        = data_[3]
        sender      = get_object_or_404(User,username=sender).username
        recipient   = get_object_or_404(User,username=recipient).username
        new_resp    = {'sender':sender,'content':content,'recipient':recipient, 'csrfmiddlewaretoken':csrf}
        qdict       = QueryDict('', mutable=True)
        qdict.update(new_resp)
        #print(qdict)
        serializer          = MxCreateSerializer(data=qdict)
        if not serializer.is_valid():
            return Response({'message':'no'})
        serializer.save()
        return Response({'message':'yes'})
  

serializers.py

 class MxCreateSerializer(serializers.ModelSerializer):
    class Meta:
        model = Message
        fields = ['sender','content','recipient']

    def create(self, validated_data):
        message = Message.objects.create(**validated_data)
        print(message)
        return message
  

Я получаю эту ошибку:

Обратная трассировка (последний последний вызов):

Тип исключения: ошибка типа в /mxcreate/

Значение исключения: Объект типа MxCreateSerializer не сериализуем в формате JSON

Спасибо за любые предложения

Данные сериализатора в ответ должны быть отправлены следующим образом

 def get(self, request, format=None):
    serializer = MxCreateSerializer()
    return Response({'serializer':serializer.data})
  

Примечание: .data с сериализатором
