如何在 Django 中成功发布与投票 API 中的问题相关联的选项？

Question

我正在创建一个调查/投票 api，我可以成功发布问题，但我收到以下错误 Choice() got an unexpected keyword argument 'question' 当我尝试创建与问题相关联的选择时，我想不通。

这些是模型

from django.db import models
import datetime
from django.utils import timezone
# Модели для опоросов
class Question(models.Model):
    poll_question = models.CharField(max_length=255, blank=False)
    title = models.CharField(max_length=255, blank=True)
    start_date = models.DateTimeField('date published', blank=False)
    
    def __str__(self):
        return self.poll_question
    
    def published_not_longage(self):
        now = timezone.now()
        return now - datetime.timedelta(days=1) <= self.start_date <= now
    
 
       
#Модель для Выбора
class Choice(models.Model):
    poll_question = models.ForeignKey(Question, on_delete=models.CASCADE)
    poll_question_choice = models.CharField(max_length=255)
    votes = models.IntegerField(default=0)




The choices serializer
class ChoiceSerializer(serializers.Serializer):
    poll_question_choice = serializers.CharField(max_length=255)
    
    def create(self, validated_data):
        return Choice.objects.create(**validated_data)


#The choices view

- The error is arising when I pass in the question instance in the serializer.save() method.

@api_view(['POST'])
def choice_details(request, pk):
    question = Question.objects.get(pk=pk)
    # question = get_object_or_404(Question, pk=pk)
    serializer = ChoiceSerializer(data=request.data)
    if serializer.is_valid():
        poll_question_choice = serializer.save(question=question)
        return Response(ChoiceSerializer(poll_question_choice).data, status=status.HTTP_201_CREATED)
    return  Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

根据模型Choice，该字段被命名为poll_question，因此需要在save 中使用（而不是question）：

poll_question_choice = serializer.save(poll_question=question)
