可以“列表显示”在Django ModelAdmin中显示ForeignKey字段的属性？ [英] Can "list_display" in a Django ModelAdmin display attributes of ForeignKey fields?

问题描述

我有一个与书有外键关系的人物模型。书有很多领域，但我最关心的是作者（标准的CharField）。

I have a Person model that has a foreign key relationship to Book. Book has a number of fields, but I'm most concerned about "author" (a standard CharField).

据说，在我的PersonAdmin模型中， d喜欢使用list_display显示book.author。我已经尝试了所有这些明显的方法（见下文），但似乎没有任何效果。任何建议？

With that being said, in my PersonAdmin model, I'd like to display "book.author" using "list_display". I've tried all of the obvious methods for doing so (see below), but nothing seems to work. Any suggestions?

class PersonAdmin(admin.ModelAdmin):
  list_display = ['book.author',]

推荐答案

作为另一个选择，你可以做一些查找： / p>

As another option, you can do look ups like:

class UserAdmin(admin.ModelAdmin):
    list_display = (..., 'get_author')

    def get_author(self, obj):
        return obj.book.author
    get_author.short_description = 'Author'
    get_author.admin_order_field = 'book__author'
