如何动态地指定“list_display”一个django ModelAdmin类的属性？ [英] How can I dynamically specify the "list_display" attribute of a django ModelAdmin class?

问题描述

在尝试动态更改django管理员模型列表页面中显示的列时，我尝试将我的ModelAdmin类的 __ init __（）方法重写为根据当前用户的权限，从list_display属性动态添加或删除特定字段。但是，我发现ModelAdmin类只能在每次重新启动时实例化一次，因此不起作用。

In trying to dynamically change the columns that are displayed in the model-list page of the django admin, I tried overriding the __init__() method of my ModelAdmin class to dynamically add or remove a particular field from the list_display attribute, depending on the permissions of the current user. However, I found that ModelAdmin classes are only instantiated once per restart, so that doesn't work...

是否有另一种方式动态更改list_display字段？ / p>

Is there another way to dynamically change the list_display field?

票据＃14206 表示此功能已添加到django前一段时间（1.4版，我相信）。 ModelAdmin类现在支持get_list_display（）方法：

Ticket #14206 indicates that this feature was added to django some time ago (version 1.4, I belive). ModelAdmin classes now support a get_list_display() method:

def get_list_display(self, request):
    if request.user.has_perm('my_app.my_permission'):
        list_display = ('field_1', 'field_2', 'dynamic_field',)
    else:
        list_display = ('field_1', 'field_2',)
    return list_display
