(stat='1')
change_up.short_description = "up" #Rewrite Action Display Name
def change_down(modeladmin, request, queryset):
(stat='0')
change_down.short_description = "down"
class imgAdmin():
list_display = ('title','summary','file','stat')
fields = ('title',)
actions = [change_up,change_down] #Bind Action
