How to create object with Foreign Key - json

Question

Fisrt,here is my models:
class Question(models.Model):
description = models.CharField(max_length=200)
analysis = models.CharField(max_length=50)
def __str__(self):
return self.description
class QuestionOption(models.Model):
question = models.ForeignKey(Question,related_name='options')
content = models.CharField(max_length=100)
isAnswer = models.BooleanField()
def __str__(self):
return self.question.description + " " + self.content
My Serializers:
class QuestionSerializer(ModelSerializer):
class Meta:
model = Question
fields = '__all__'
The Serializer of QuestionOption is as same
My ViewSet:
class QuestionViewSet(ModelViewSet):
queryset = Question.objects.all()
serializer_class = QuestionRetriveSerilzer
I want to post a Json data,like this:
{
"options": [
{
"content": "This is the first option",
"isAnswer": false
},
{
"content": "This is the second option",
"isAnswer": true
}
],
"description": "which one is true?",
"analysis": "It's esay"
}
I hope my QuestionViewSet can create a Question and two QuestionOption for me automatically，and when I post that Json data,the options is null list,so I override the create method of QuestionViewSet,like this:
def create(self, request, *args, **kwargs):
serializer = QuestionSerializer(data=request.data)
question = serializer.save()
for data in request.data['options']:
data['question'] = question.id
optionSeializer = OptionSerializer(data=data)
print optionSeializer.is_valid()
optionSeializer.save()
return Response(serializer.data,status=status.HTTP_200_OK)
And this method can work,but I want to find a simpler way to do it,cause I must override update and other methods,it's not a easy task...
So how to design Serializers and ViewSet in order to automatically create objects and update objects with foreign key ?
