如何使用一个URI获取多个资源

Question

当我发出这个curl命令时：curl http://localhost/refeq/v1/vehiclesequipements/?format=json -s | jq .我得到：

{
"objects":[
{ 
"vehicle_id": 9759,
"resource_uri": "/refeq/v1/vehiclesequipements/9759/",
"noArticle": "",
"name": "OBCIV_TFT2",
"mac": "84:7e:40:e9:f2:1e"
},
{
"vehicle_id": 9899,
"resource_uri": "/refeq/v1/vehiclesequipements/9899/",
"noArticle": "",
"name": "FILM_FRONT",
"mac": "00:40:9d:a2:36:fe"
},
{
"vehicle_id": 9899,
"resource_uri": "/refeq/v1/vehiclesequipements/9899/",
"noArticle": "",
"name": "OBCIV_TFT1",
"mac": "84:7e:40:ea:a4:36"
}
],
"meta": {
"total_count": 3,
"offset": 0,
"limit": 0
}
}

我想获得两个关于车辆的资源_id:9899

得到这样的东西：

{
"objects":[
{
"vehicle_id": 9899,
"resource_uri": "/refeq/v1/vehiclesequipements/9899/",
"noArticle": "",
"name": "FILM_FRONT",
"mac": "00:40:9d:a2:36:fe"
},
{
"vehicle_id": 9899,
"resource_uri": "/refeq/v1/vehiclesequipements/9899/",
"noArticle": "",
"name": "OBCIV_TFT1",
"mac": "84:7e:40:ea:a4:36"
}
],
"meta": {
"total_count": 2,
"offset": 0,
"limit": 0
}
}

我面临的问题是curl http://localhost/refeq/v1/vehiclesequipements/9899/?format=json -s退货：More than one resource is found at this URI.

如何返回多个具有resssource_uri的资源？

我看了医生，但我不明白如何做到这一点。。

这是我的api.py

from tastypie.resources import ModelResource
from tastypie.serializers import Serializer
from tastypie.authorization import Authorization
from refeq.models import VehiclesEquipements
USE_LOCAL_TIME = True
class MyDateSerializer(Serializer):
def format_datetime(self, data):
return data.strftime("%Y-%m-%dT%H:%M:%S")
class VehiclesEquipementsResource(ModelResource):
class Meta:
queryset = VehiclesEquipements.objects.all()
resource_name = 'vehiclesequipements'
#filtering = {"vehicle_id":["exact","in"]}
authorization=Authorization()
limit = 0
max_limit = 0
if USE_LOCAL_TIME:
serializer = MyDateSerializer()

和型号.py

class VehiclesEquipements(models.Model):
vehicle_id = models.IntegerField(primary_key=True)
noArticle = models.CharField(max_length=30, blank=True)
name = models.CharField(max_length=30, blank=True)
mac = models.CharField(max_length=30, blank=True)
class Meta:
db_table = 'vw_vehicles_equipements'
managed = False

最后说明：我无法使用uri筛选：

curl 'http://dope-apipc01/refeq/v1/vehiclesequipements/?format=json&vehicle_id__exact=9899'

我是Django和tastypie的新手。。。感谢您的帮助。

访问资源似乎必须具有唯一的resource_uri，否则返回异常MultipleObjectsReturned。
