Let's say I have Books and Author models.
假设我有书籍和作者模型。
class Author(models.Model):
name = CharField(max_length=100)
class Book(models.Model):
title = CharField(max_length=250)
authors = ManyToManyField(Author)
I want each Book to have multiple Authors, and on the Django admin site I want to be able to add multiple new authors to a book from its Edit page, in one go. I don't need to add Books to authors.
我希望每本书都有多个作者,在Django管理网站上,我希望能够一次性从编辑页面中将多个新作者添加到一本书中。我不需要为作者添加书籍。
Is this possible? If so, what's the best and / or easiest way of accomplishing it?
这可能吗?如果是这样,最好和/或最简单的方法是什么?

It is quite simple to do what you want, If I am getting you correctly:
做你想做的事很简单,如果我找到你的话:
You should create an admin.py file inside your apps directory and then write the following code:
您应该在apps目录中创建一个admin.py文件,然后编写以下代码:
from django.contrib import admin
from myapps.models import Author, Book
class BookAdmin(admin.ModelAdmin):
model= Book
filter_horizontal = ('authors',) #If you don't specify this, you will get a multiple select widget.
admin.site.register(Author)
admin.site.register(Book, BookAdmin)

Try this:
尝试这个:
class AuthorInline(admin.TabularInline):
model = Book.authors.through
verbose_name = u"Author"
verbose_name_plural = u"Authors"
class BookAdmin(admin.ModelAdmin):
exclude = ("authors", )
inlines = (
AuthorInline,
)
You might need to add raw_id_fields = ("author", )
to AuthorInline
if you have many authors.
如果您有许多作者,则可能需要将raw_id_fields =(“author”,)添加到AuthorInline。
