例子，添加一个方法，批量更新文章，代码如下:
from django.contrib import admin
from myapp.models import Article
def make_published(self, request, queryset):
rows_updated = queryset.update(status=’p’)
if rows_updated == 1:
message_bit = "1 story was"
else:
message_bit = "%s stories were" % rows_updated
self.message_user(request, "%s successfully marked as published." % message_bit)
class ArticleAdmin(admin.ModelAdmin):
list_display = [’title’, ’status’]
ordering = [’title’]
actions = [make_published]
admin.site.register(Article, ArticleAdmin)
效果如下：
自定义动作的权限控制，重载get_actions方法，如下：（只允许名字以J大头的删除记录）
from django.contrib import admin
from myapp.models import Article
def make_published(self, request, queryset):
rows_updated = queryset.update(status=’p’)
if rows_updated == 1:
message_bit = "1 story was"
else:
message_bit = "%s stories were" % rows_updated
self.message_user(request, "%s successfully marked as published." % message_bit)
class ArticleAdmin(admin.ModelAdmin):
list_display = [’title’, ’status’]
ordering = [’title’]
actions = [make_published]
def get_actions(self, request):
actions = super(MyModelAdmin, self).get_actions(request)
if request.user.username[0].upper() != ’J’:
if ’delete_selected’ in actions:
del actions[’delete_selected’]
return actions
