我正在从 django 后端的 api 获取数据并序列化数据以获取所需的字段并将其发送到前端
序列化器
class EventSearchOutputSerialiser(Serializer):
date_time = DateTimeField(source='dates.start.dateTime')
icon = URLField(source='images.0.url', allow_null=True)
event = CharField(source='name')
genre = CharField(source='classifications.0.genre.name')
venue = CharField(source='_embedded.venues.0.name')
所以基本上我在这里尝试从嵌套字段中提取数据。
获取的数据将被传递以进行序列化的示例。此数据是从 Ticketmaster api 获取的。

我遇到了问题 基本上我以错误的方式理解了关键字 source 的含义 source 关键字描述的是输出字段而不是传递对象的属性
