-url控制

　　-传统的url配置

	url(r'^books/$', views.BookView.as_view()),

	url(r'^books/(?P<pk>\d+)$', views.BookDetailView.as_view()),

　　-半自动

	url(r'^publish/$', views.PublishView.as_view({'get':'list','post':'create'})),

	url(r'^publish/(?P<pk>\d+)/$', views.PublishView.as_view({'get':'retrieve','put':'update','delete':'destroy'})),

　　-全自动(了解)

	-能自动生成多条路由
