将admin date_hierarchy设置为ForeignKey日期字段 [英] Set admin date_hierarchy to a ForeignKey date field

问题描述

当我尝试设置

date_hierarchy = "schedule__date"  

计划是外键的地方。

我收到以下错误。

'TestAdmin.date_hierarchy' refers to field 'schedule__date' that is missing from model 'testing.Test'.

我了解此错误。我希望这里有一种解决方法，可以让我从外键日期字段获得date_hierarchy。我尝试在Test模型中设置一个返回日期的方法和属性，并将该方法/属性设置为date_hierarchy，但是没有运气。

I understand the error. What I'm hoping for is that there is some sort of workaround here to allow me to have date_hierarchy from a foreign key date field. I have tried setting a method and propery within the Test model that returns the date and setting that method/property as the date_hierarchy, but no luck.

当我已经通过外键将其存储在另一个表中时，不得不在schedule_date的表中添加另一列似乎很愚蠢。

It seems foolish to have to add another column to my table for the schedule__date when I already have it stored in another table from the foreign key.

推荐答案

不幸的是，当前的django无法做到这一点。明确要求 date_hierarchy 选项是 DateTimeField 或 DateField ：

Unforturnately, this isn't possible with the current django. The date_hierarchy option is explicitly required to be a DateTimeField or DateField:
