问题: 怎么才能实现 和drf最佳实践里面 类似的url
GET /cars/711/drivers/ Returns a list of drivers for car 711
GET /cars/711/drivers/4 Returns driver #4 for car 711

代码:

model

class Car(models.Model):
    name = models.CharField(u'车名', max_length=10)


class Driver(models.Model):
    name = models.CharField(u'人名',max_length=10)
    car = models.ForeignKey(Car, related_name='drivers', verbose_name='司机')

serializers

class CarSerializer(serializers.ModelSerializer):
    class Meta:
        model = Car
        fields = ('name',)


class DriverSerializer(serializers.ModelSerializer):
    car = CarSerializer(many=False)
    class Meta:
        model = Driver
        fields = ('name', 'car')

views:

class CarViewSet(viewsets.ModelViewSet):
    queryset = Car.objects.all()
    serializer_class = CarSerializer


class DriverSerializer(viewsets.ModelViewSet):
    queryset = Driver.objects.all()
    serializer_class = DriverSerializer
    

urls：

root_router = DefaultRouter()

root_router.register(r'cars', CarViewSet, base_name='cars')
