如何在DRF中使用API调用创建多个模型实例(具有一对多关系)

from rest_framework.views import APIView
from rest_framework.response import Response
from .serializers import ParentModelSerializer, ChildModelSerializer
from .models import ParentModel, ChildModel

class CreateModelsAPIView(APIView):
    def post(self, request):
        parent_data = request.data.get('parent')  # 获取主模型实例的数据
        child_data = request.data.get('children')  # 获取子模型实例的数据

        parent_serializer = ParentModelSerializer(data=parent_data)
        if parent_serializer.is_valid():
            parent_instance = parent_serializer.save()  # 创建主模型实例
        else:
            return Response(parent_serializer.errors, status=400)

        child_serializer = ChildModelSerializer(data=child_data, many=True)
        if child_serializer.is_valid():
            child_serializer.save(parent=parent_instance)  # 创建子模型实例，并关联到主模型实例
        else:
            parent_instance.delete()  # 如果子模型实例验证失败，则删除已创建的主模型实例
            return Response(child_serializer.errors, status=400)

        return Response({'message': 'Models created successfully'}, status=201)
