如何在CreateAPIVIew的响应中插入数据

from rest_framework.generics import CreateAPIView

class MyCreateView(CreateAPIView):
    serializer_class = MySerializer
    queryset = MyModel.objects.all()

from rest_framework import serializers

class MySerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = '__all__'

class MyCreateView(CreateAPIView):
    serializer_class = MySerializer
    queryset = MyModel.objects.all()

    def create(self, request, *args, **kwargs):
        # 获取请求数据
        data = request.data

        # 在数据保存之前进行数据插入操作
        data['extra_field'] = 'extra_value'

        # 调用父类的create方法保存数据
        return super().create(request, *args, **kwargs)
