在django教程中，was_published_recently.admin_order_field ='pub_date' [英] From the django tutorial was_published_recently.admin_order_field = 'pub_date'

问题描述

来自django教程

 was_published_recently.admin_order_field = 'pub_date'

这句话到底在做什么?

推荐答案

这是django的admin部分的参考.

This is in reference to the admin section of django.

在与模型相对应的管理部分中，每个模型都有一个名为

In the admin section corresponding to models, each models has a property called list_display, which control which fields are displayed on the change list (list display of all the objects) page of the admin.

现在，如果您希望在 list_display 中更改 was_published_recently 的默认排序顺序，则可以通过设置 admin_order_field 属性来进行.

Now, if you wish to change the default sort order for was_published_recently in the list_display you can do so by setting the admin_order_field attribute.

因此，在示例中:

class Poll(models.Model):
    # ...
    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
    was_published_recently.admin_order_field = 'pub_date'
    was_published_recently.boolean = True
    was_published_recently.short_description = 'Published recently?'

您要添加一个名为 was_published_recently 的自定义列，并在列 was_published_recently <的"sort"选项中将排序顺序指定为数据库字段 pub_date ./code>单击.

You are adding a custom column called was_published_recently and specifying the sort order to be the database field pub_date when the "sort" option for the column was_published_recently is clicked.
