在django admin中将外部模型字段显示为可编辑

问题描述

我有一个带外键的Django模型:

I have a Django Model with a Foreign key:

class Library:
  name=models.CharField()

class Book:
  title=models.CharField()
  library=models.ForeignKey(Library)

models.py

class BookAdmin(admin.ModelAdmin):
  extra = 0
  fields = ['title', 'library__name'] # library__name not found

admin.site.register(Book, BookAdmin)

admin.py

在管理员中，我要显示 Book ，并在 Book 中显示 Library.name 的可编辑字段.代码>视图(与内联相反):

In the admin, I want to display Book and show an editable field for Library.name in the Book view (not the other way around with inlines):

> Book
  * Title: "Foo"
  * Library Name: "Bar"

这是只读的，很容易(只是在Book模型中创建一个返回库名值的方法)，但是我无法使其适用于可编辑字段，因此我尝试使用 fields =('title'，'library.name')和 fields =('title'，'library__name')没有成功

As readonly, it's easy (just creating a method in Book model returning the library name value) but I cannot make it work for editable fields, I tried using fields=('title','library.name') and fields=('title','library__name') without success

推荐答案

您需要内联模型管理员:

You need an inline model admin:
