Django管理员列排序降序 [英] Django Admin Column Sort Descending

问题描述

在将Django admin与

添加以下两行：

  ..... 
 ..... 
 th_classes = ['sortable'] 
 order_type =''
 
＃换行
 
 default_order_type = getattr（attr，  admin_order_first_type，无）
 new_order_type = default_order_type，如果default_order_type否则为'asc'
 
＃新行结尾
 
 sort_priority = 0 
 sorted = False 
 ... 
 ... 
  

现在在ModelAdmin中，您可以：

  list_display =（'number_of_players'，....）
 
 def number_of_players（self，team ）：
返回整数（team.number_of_players）
 
 number_of_players.short_description ='＃玩家数量'
 number_of_players.admin_order_field ='number_of_players'
 number_of_players.admin_order_first_type = 'desc'＃将使该列按顺序排序，首先
  

我对其进行了测试并成功

When using Django admin with grappelli I would like that a click on a column header will sort the table by descending order.

(I don't want a default ordering to the columns by defining the ordering field in the Model Meta Class.)

The default behavior is Ascending.

The first click should order like this:

解决方案

Rewrite the def result_headers(cl)

add these 2 lines:

    .....
    .....
    th_classes = ['sortable']
    order_type = ''

    #new lines

    default_order_type = getattr(attr, "admin_order_first_type", None)
    new_order_type = default_order_type if default_order_type else 'asc'

    #end of new lines

    sort_priority = 0
    sorted = False
    ...
    ...

now in the ModelAdmin you can:

list_display = ('number_of_players', ....)

def number_of_players(self, team):
        return intcomma(team.number_of_players)

number_of_players.short_description = '# num of players'
number_of_players.admin_order_field = 'number_of_players'
number_of_players.admin_order_first_type = 'desc' #will make the column to be ordered desc first

I tested it and it works
