Django：强制管理员用户在TabularInline中输入至少一个项目 [英] Django: Forcing admin users to enter at least one item in TabularInline

问题描述

在我的管理员对象主席我有一个 TabularInline 任意数量的 Desk 对象。我希望每个椅子总是至少有一个与它相关联的 Desk 对象。有没有办法使管理界面强制用户至少输入一个 Desk ？如果没有输入 Desk ，则显示错误。

In my admin for an object Chair I have a TabularInline for an arbitrary number of Desk objects. I want every Chair to always have at least one Desk object associated with it. Is there a way to make the admin interface force the user to enter at least one Desk? Like show an error if no Desk is entered?
