##***************第二种继承方法

from app01 import seria2
from rest_framework import mixins
from rest_framework import generics

class PublsherGenView(generics.ListCreateAPIView):

    queryset = models.Publisher.objects.all()
    serializer_class = seria2.PublisherModelSerializer

    serializer_class = seria2.BookModelSerializer

class BookDetailGen(generics.RetrieveUpdateDestroyAPIView):

    queryset = models.Book.objects.all()
    serializer_class = seria2.BookModelSerializer


#####*********第三种********viewsets.ModelViewSet**
from rest_framework import viewsets
class BookViewSet(viewsets.ModelViewSet):
    queryset = models.Book.objects.all()
    serializer_class = seria2.BookModelSerializer

urls.py

from django.conf.urls import url,include
from django.contrib import admin
from app01 import views

#第三种url简写
#简写第一步
from rest_framework import routers

routers = routers.DefaultRouter()
routers.register(r"books001",views.BookViewSet) #books001为URL前缀



urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^publisher/$', views.PublsherMixView.as_view()),
    # url(r'^publisher/(d+)/$', views.PublisherDetailView.as_view()), #不加超链接
    url(r'^publisher/(?P<pk>d+)/', views.PublisherDetailMix.as_view(), name="publisher_detail"),


    url(r'^book/$', views.BookMixView.as_view()),
    url(r'^book/(?P<pk>d+)/$', views.BookDetailMix.as_view()),

    ##**********第二种*******
    url(r'^publishers/$', views.PublsherGenView.as_view()),
    url(r'^publishers/(?P<pk>d+)/$', views.PublisherDetailGen.as_view()),

    url(r'^books/$', views.BookGenView.as_view(),name="book_list"),
    url(r'^books/(?P<pk>d+)/$', views.BookDetailGen.as_view(),name="book_detail"),

    ##*****第三种 这种还可以简写
    # url(r'^books1/$', views.BookViewSet.as_view({"get":"list","post":"create"}),name="book_list"),
    # url(r'^books1/(?P<pk>d+)/$', views.BookViewSet.as_view({
    #             'get': 'retrieve',
    #             'put': 'update',
    #             'patch': 'partial_update',
    #             'delete': 'destroy'
    #         }),name="book_detail"),


    ##简写第二步
    url(r'^', include(routers.urls)),


]

#简写默认生成如下url
# # ^books001/$ [name='book-list']
# ^ ^books001.(?P<format>[a-z0-9]+)/?$ [name='book-list']
# ^ ^books001/(?P<pk>[^/.]+)/$ [name='book-detail']
# ^ ^books001/(?P<pk>[^/.]+).(?P<format>[a-z0-9]+)/?$ [name='book-detail']
