Question

喜欢标题，
django-rest-framework中list_route和detail_route的不同之处是什么？
如果我想在网址1中获取xxx/books/1/，如何撰写url.py和views.py？

Answer 1

**阅读本文，肯定会有所不同，以及如何使用它**

如果我们有一个ad hoc方法（例如，当前方法与我们用于不同方法的视图集相同，基本上 ad-hoc意味着'这个'），我们可以使用自定义路由为这个方法，我们可以在@list_route和@中的方法上面定义我们自己的url @detail_route装饰者

@ list_route和@detail_route之间的区别在于@detail_route装饰器在其URL模式中包含pk，适用于需要单个实例的方法。 @list_route装饰器适用于对象列表（记录列表）进行操作的方法

通过获取参考资料 enter link description here

例如

**It will hit to the same url at the url.py but for @list_raoute we have append /reset-user-password/ which we have mention on @list_route to the url when we call it.(e.g 

/// In url.py**

router = routers.DefaultRouter()

router.register(r'register', api_views.UserProfileViewSet,  base_name="userprofileviewset")
urlpatterns = [
    url(r'^api/v1/', include(router.urls)),
]

** //////在API通话或网址调用中

用于创建用户**

http://127.0.0.1:8000/api/v1/register/

###忘记密码

detail_route，是一个实例。我的意思是，用细节路线生成的方法将在实例方法之后附加，即检索。 {前缀} / {查找} /

检查：django drf router doc

如果您的模型图书且 1 是ID：

class ParkingViewSet(viewsets.ModelViewSet):
serializer_class = BookSerializer

def retrieve(self, request, pk=None):
    # Here pk will be 1.
    queryset = Book.objects.get(pk=pk)         
    serializer = BookSerializer(queryset)                         
    return Response({'msg':"",'data':serializer.data, 'status':'OK'})

如果xxx是您的实例，您应该使用url_path变量来更改默认网址。像这样：

@detail_route(methods=['get'], url_path='(books/?P<num>\d+)')

然后在该方法中，您将使用num作为参数

urls.py，将使用默认路由器生成：

from django.conf.urls import url, include                                        
from recharge_card import views                                                  
from rest_framework.routers import DefaultRouter                                 

# Create a router and register our viewsets with it.                             
router = DefaultRouter()                                                         
router.register(r'xxx', views.XxxViewSet, base_name="xxx")  

urlpatterns = [  
    url(r'^api/', include(router.urls)),                                         
]
