Question

我想在api响应中进行数据过滤。即做出这样的地址

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

现在我的代码：

    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。该网址无效

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并且看到错误

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.

为什么我的路由器无法正常工作，以及如何使路由器正常工作？谢谢！

更改以下行：

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

要这样：

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

另外，请注意，CoinCostViewSet中没有视图，因此可以添加操作或使用类似viewsets.ModelViewSet的类：

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

具有Viewset查询集过滤器的Django REST Framework中的路由器
