Question

我有3个型号：BzMediaMusician，BzMediaSinger和BzMediaAlbum。 BzMediaAlbum有2个字段id_singer和id_musician与2个模型BzMediaMusician，BzMediaSinger相关。

在这里，id_singer和id_musician可以为null，因为某些专辑没有

id_singer = models.ForeignKey('BzMediaSinger', null=True, blank=True, db_column='id_singer')
id_musician = models.ForeignKey('BzMediaMusician', null=True, blank=True, db_column='id_musician')

我已请求httpx：// localhost：8000 / api / album /获取结果

{
"meta": {
"limit": 20,
"next": "/api/album/?limit=20&offset=20",
"offset": 0,
"previous": null,
"total_count": 501
},
"objects": [
{
"album_cat": "69",
"album_name_ascii": "truong ca kinh pho mon",
"album_viewed": 1618,
"album_viewed_month": 0,
"des": "Võ Tá Hân phổ nhạc",
"id_album": 7,
"name_en": "",
"name_vn": "Trường ca kinh Phổ Môn",
"order": "1",
"pic_thumb": "http://local.com/nhac/img/truong_ca_kinh_pho_mon.jpg",
"resource_uri": "/api/album/7/"
},]

上面的结果是它不包含id_singer和id_musician。我所需要的就是在这两个领域拥有音乐家和歌手的完整信息。请帮忙。
