Django Rest-Framework 嵌套序列化器顺序

所以基本上顺序 song_set 下面的 json 数据显示从最近到最新创建的对象，在本例中为 order_by('-timestamp') 或 order_by('-pk')

json数据

class Album(models.Model):
    album_name     = models.CharField(max_length=100, blank=True)
class Song(models.Model):
    album          = models.ForeignKey('album.Album', default=1)
    timestamp      = models.DateTimeField(auto_now_add=True, auto_now=False)
class SongListSerializer(HyperlinkedModelSerializer):
    class Meta:
        model = Song
        fields = [
            'pk',
            'timestamp'
class AlbumSerializer(HyperlinkedModelSerializer):
    song_set = SongListSerializer(many=True, read_only=True)
    class Meta:
        model = Album
        fields = [
            'pk',
            'timestamp',
            'song_set'
