使用 Django REST framework 的 Viewsets

 

简单点说，DRF的Viewsets就允许你将一批功能类似或者有流程的接口写在一个类里面。

比如我有一个流程：需要先A, 后B，再C，后D，完成4个顺序接口，则可以这样使用Viewsets。

view.py

view.py
from rest_framework import viewsets
from rest_framework.decorators import list_route
class UserViewSet(viewsets.GenericViewSet):
"""
A viewset that provides the standard actions
"""

@list_route(methods=['post'])
def A(self, request):
return Response('A')

@list_route(methods=['get'])
def B(self, request):
return Response('B')

@list_route(methods=['post'])
def C(self, request):
return Response('C')

@list_route(methods=['get'])
def D(self, request):
return Response('D')

url.py
from django.conf.urls import url
from rest_framework.routers import DefaultRouter

from rs_account.views import (
UserViewSet
)

router = DefaultRouter()
router.register(r'user', UserViewSet, base_name='user')

urlpatterns = [
# search question
]

urlpatterns += router.urls

这样配置完，你就有4个接口URL：

post /user/A/
get /user/B/
post /user/C/
get /user/D/

DRF 3.8 更新
根据最新的官方文档，在DRF 3.8这个版本使用 @action 代替了 @list_router和@detail_router。

Deprecations
action decorator replaces list_route and detail_route
#5705 list_route and detail_route have been merge into a single action decorator. This improves viewset action introspection, and will allow extra actions to be displayed in the Browsable API in future versions.

Both list_route and detail_route are now pending deprecation. They will be deprecated in 3.9 and removed entirely in 3.10.

The new action decorator takes a boolean detail argument.

Replace detail_route uses with @action(detail=True).
Replace list_route uses with @action(detail=False).
