django rest框架manytomy字段排序

我有以下型号:

class BusStop(m.Model):
    street_name = m.CharField(max_length=255)

    class Meta:
        ordering = ['street_name']
    ...

class Carrier(m.Model):
    name = m.CharField(max_length=255)
    ...

class CarrierStop(m.Model):
    bus_stop = m.ManyToManyField(BusStop, related_name='carrier_stop_fk')
    carrier = m.ForeignKey(Carrier, on_delete=m.CASCADE, related_name='test_carrier_fk')

我做了序列化程序:

    class CarrierStopSerializer(serializers.ModelSerializer):
        carrier = serializers.StringRelatedField()
        bus_stop = serializers.StringRelatedField(many=True)

             class Meta:
                    model = CarrierStop
                    fields = ['id', 'carrier', 'bus_stop']

我有一些BusStop模型的对象,序列化程序给出如下表示:

    [
        {
            "id": 1,
            "carrier": "Fremiks",
            "bus_stop": [
                    "Armii Krajowej",
                    "Kino Lot 01",
                    "KosynierÃ³w I 02"
            ]
        }
    ]

从carriersTopSerializer返回按名称排序的公共汽车站字段。我想按ID订购中间表carrierstop_bus_站,由Django Manytomy字段创建。我知道我应该使用序列化方法字段而不是StringRelatedField(或者PrimaryKeyRelatedField,不重要),但我不确定如何准确地做到这一点。
