如何在不使用视图集的情况下序列化Django中带注释的字段？

from rest_framework import serializers

class MySerializer(serializers.Serializer):
    my_field = serializers.CharField()

    def to_representation(self, instance):
        data = super().to_representation(instance)
        # 在这里对带注释的字段进行处理
        data['my_field'] = instance.my_field  # 假设my_field是一个带注释的字段
        return data

from rest_framework.views import APIView
from rest_framework.response import Response

class MyView(APIView):
    def get(self, request):
        queryset = MyModel.objects.all()  # 假设MyModel是你要序列化的模型
        serializer = MySerializer(queryset, many=True)
        return Response(serializer.data)
