如何动态指定“list_display"?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

在尝试动态更改在 django 管理员的模型列表页面中显示的列时，我尝试覆盖我的 ModelAdmin 类的 __init__() 方法以动态添加或删除特定的list_display 属性中的字段，具体取决于当前用户的权限.但是，我发现 ModelAdmin 类每次重启只会实例化一次，所以这不起作用...

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...

还有其他方法可以动态更改 list_display 字段吗?

Is there another way to dynamically change the list_display field?

Ticket #14206 表示这个功能是前段时间加入django的(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
