如何在django restframework中将多个数据写入嵌套序列化程序

# models.py
from django.db import models

class ChildModel(models.Model):
    name = models.CharField(max_length=100)
    # other fields

class ParentModel(models.Model):
    name = models.CharField(max_length=100)
    children = models.ManyToManyField(ChildModel)

# serializers.py
from rest_framework import serializers

class ChildSerializer(serializers.ModelSerializer):
    class Meta:
        model = ChildModel
        fields = '__all__'

class ParentSerializer(serializers.ModelSerializer):
    children = ChildSerializer(many=True)

    class Meta:
        model = ParentModel
        fields = '__all__'

# views.py
from rest_framework import viewsets
from .models import ParentModel
from .serializers import ParentSerializer

class ParentViewSet(viewsets.ModelViewSet):
    queryset = ParentModel.objects.all()
    serializer_class = ParentSerializer

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        return Response(serializer.data, status=status.HTTP_201_CREATED)
