Django:使用一些自定义列序列化queryset，并格式化一些字段

from rest_framework import serializers

class CustomSerializer(serializers.Serializer):
    # 定义需要序列化的字段
    field1 = serializers.CharField()
    field2 = serializers.IntegerField()

    # 自定义序列化方法
    def to_representation(self, instance):
        # 对字段进行格式化处理
        formatted_field1 = instance.field1.upper()
        formatted_field2 = instance.field2 * 2

        # 返回格式化后的字段值
        return {
            'field1': formatted_field1,
            'field2': formatted_field2
        }

from rest_framework.response import Response
from .serializers import CustomSerializer
from .models import YourModel

def your_view(request):
    queryset = YourModel.objects.all()
    serializer = CustomSerializer(queryset, many=True)
    serialized_data = serializer.data

    return Response(serialized_data)
