Django使用一个字段进行反序列化，但使用其他字段进行序列化

from rest_framework import serializers

class MySerializer(serializers.Serializer):
    serialized_field = serializers.CharField()
    deserialized_field = serializers.CharField()

    def to_representation(self, instance):
        # 序列化对象时，使用其他字段来生成serialized_field的值
        serialized_value = instance.other_field + 'some_string'
        return {
            'serialized_field': serialized_value,
            'deserialized_field': instance.deserialized_field
        }

    def to_internal_value(self, data):
        # 反序列化对象时，使用deserialized_field的值作为deserialized_field字段的值
        deserialized_value = data.get('deserialized_field', None)
        return {
            'serialized_field': deserialized_value,  # 也可以根据deserialized_field的值生成serialized_field的值
            'deserialized_field': deserialized_value
        }
