urls.py

# /music/alubm/add/
  url(r'^album/add/$', views.AlbumCreate.as_view(), name="album-add"),

　　# /music/alubm/3/update/
　　url(r'^album/(?P<pk>\d+)/update/$', views.AlbumUpdate.as_view(), name="album-update"),

　　# /music/alubm/3/delete/
　　url(r'^album/(?P<pk>\d+)/delete/$', views.AlbumDelete.as_view(), name="album-delete"),

views.py

from django.views.generic.edit import CreateView, UpdateView, DeleteView

from django.core.urlresolvers import reverse_lazy

class AlbumCreate(CreateView):
    model = Album
    fields = ['artist', 'album_title', 'genre', 'album_logo']
    # default: template_name =  <app_name>/<model_name>_form.html   创建、更新、删除的默认模板都是这个,这里为：music/album_form.html

class AlbumUpdate(UpdateView):
    model = Album
    fields = ['artist', 'album_title', 'genre', 'album_logo']

class AlbumDelete(DeleteView):
    model = Album
    success_url = reverse_lazy('music:index')   #删除成功后，当前页面将不存在了，所以需要重定向一下

form-template.html   通用模板，可通过include标签引入

{% for field in form %}
