如何在django rest框架中从JSONField中删除多余的数据？

from rest_framework.views import APIView
from rest_framework.response import Response
from .models import YourModel
from .serializers import YourSerializer

class YourView(APIView):
    def post(self, request):
        serializer = YourSerializer(data=request.data)
        if serializer.is_valid():
            json_data = serializer.validated_data['your_json_field']
            # 删除多余的字段
            json_data.pop('field_to_be_deleted', None)
            # 保存更新后的数据
            instance = YourModel.objects.create(your_json_field=json_data)
            return Response({'message': 'Data updated successfully.'})
        else:
            return Response(serializer.errors, status=400)
