django drf框架自带的路由及最简化的视图

from rest_framework.routers import SimpleRouter

router = SimpleRouter()

router = SimpleRouter()
# 注册各种接口路由
router.register('cars', views.CarModelViewSet, base_name='car')
#car为链接的开头,views.CarModelViewSet为当路由为cars的时候的调用的函数
urlpatterns = []
urlpatterns.extend(router.urls)

urlpatterns = [
 url(r'^cars/$', views.CarModelViewSet.as_view()),
 url(r'^cars/(?P<pk>.*)/$', views.CarModelViewSet.as_view()),
]

from rest_framework.viewsets import ModelViewSet

class ModelViewSet(mixins.CreateModelMixin,
     mixins.RetrieveModelMixin,
     mixins.UpdateModelMixin,
     mixins.DestroyModelMixin,
     mixins.ListModelMixin,
     GenericViewSet):
 #所有他当中以及对于get等等的方法自动进行了封装
mixins是在generics再进行方法的分装成5个方法
RetrieveModelMixin：retrieve 单取
ListModelMixin：list 群取
CreateModelMixin：create 单增
UpdateModelMixin：update 单整体改
UpdateModelMixin: partial_update 单局部改
DestroyModelMixin：destroy 单删
class CarModelViewSet(ModelViewSet):
 queryset = models.Car.objects.filter(is_delete=False) 
 serializer_class = serializers.CarModelSerializer
 ........
 #queryset serializer_class 必须给与
 ...
 def get(self):
  他会调用retrieve或者list方法其他也类似
  .....
