具有视图集查询集过滤器的 Django REST Framework 中的路由器

Question

我想在 api 响应中进行数据过滤。即制作这样的地址

/api/v1//CoinCost?coin_id=coin_name&dateStart=2020-02-06T00:00:00&dateEnd=2020-02-08T00:00:00

我现在的代码：

    from django_filters import rest_framework as filters

class CoinCostFilterSet(filters.FilterSet)
    class Meta:
        model = CoinCost
        fields = {
            'coin_id': ['exact'],
            'timestamp': ['gt', 'lt'],
        }

class CoinCostViewSet(viewsets.ViewSet):
    queryset = CoinCost.objects.all()
    serializer_class = CoinCostsSerializer
    filter_backends = (filters.DjangoFilterBackend,)
    filterset_class = CoinCostFilterSet

还有我的urls.py。这个url没用

from django.urls import path, include
from . import views
from .views import CoinsView, CoinsCostsView, CoinCostViewSet
from django.views import generic

from rest_framework.routers import DefaultRouter

router = DefaultRouter()
router.register('CoinCost/$', CoinCostViewSet, basename='Coins')

app_name = 'Coins'

urlpatterns = [
    path('coins/', CoinsView.as_view()),
    path('coins_costs/update/', views.coins_costs_load),
    path('coins_load/update/', views.coins_load),
    path('', include(router.urls)),
    ]

我尝试 /api/v1/CoinCost?coin_id=bulbacoin 我看到错误

Using the URLconf defined in myminter.urls, Django tried these URL patterns, in this order:

admin/
api/v1/ coins/
api/v1/ coins_costs/update/
api/v1/ coins_load/update/
api/v1/ ^$ [name='api-root']
api/v1/ ^\.(?P<format>[a-z0-9]+)/?$ [name='api-root']
The current path, api/v1/CoinCost/, didn't match any of these.

为什么我的路由器不工作以及如何制作一个工作的路由器？谢谢！

更改以下行：

router.register('CoinCost/$', CoinCostViewSet, basename='Coins')

像这样:

router.register('CoinCost', CoinCostViewSet, basename='Coins')

另外请注意，您的 CoinCostViewSet 中没有视图，因此请添加操作或使用 class，例如 viewsets.ModelViewSet:

class CoinCostViewSet(viewsets.ModelViewSet):
    queryset = CoinCost.objects.all()
    serializer_class = CoinCostsSerializer
    filter_backends = (filters.DjangoFilterBackend,)
    filterset_class = CoinCostFilterSet
