Django:StackedInline 的更友好的标题，用于通过模型自动生成?

2022-01-25 00:00:00 python django django-admin

问题描述

我用的是Django admin StackedInline，如下:

I'm using a Django admin StackedInline, as follows: 

class BookInline(admin.StackedInline):
    model = Book.subject.through
    verbose_name = 'Book'
    verbose_name_plural = 'Books with this subject'

class SubjectAdmin(admin.ModelAdmin):
    inlines = [
        BookInline,
    ]

一切正常，但标题非常难看:

It all works, but the header is pretty ugly: 

Books With This Subject
Book: Book_subject object

有谁知道我可以如何摆脱或更改 Book_subject 对象 部分?

Anyone know how I can get rid of, or change, the Book_subject object part?

谢谢！

解决方案

我从来没有用过这样的m2m字段，谢谢！学到了新东西.

I've never used an m2m field like this, so thanks! Learned something new.

我找到了两种解决问题的方法:

I found 2 ways to get around the problem:

1:只需用新函数重新分配 __unicode__ 函数

1: simply reassign the __unicode__ function with a new function

class MyInline(admin.TabularInline):
    MyModel.m2m.through.__unicode__ = lambda x: 'My New Unicode'
    model = MyModel.m2m.through

2:设置代理模型对于 m2m.through 模型并改用该模型

2: set up a proxy model for the m2m.through model and use that model instead

class MyThrough(MyModel.m2m.through):
    class Meta:
        proxy = True
    def __unicode__(self):
        return "My New Unicode"

class MyInline(admin.TabularInline):
    model = MyThrough
