How can I enable inline ManyToManyFields on my Django admin site?

Question

Let's say I have Books and Author models.

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.

Is this possible? If so, what's the best and / or easiest way of accomplishing it?

It is quite simple to do what you want, If I am getting you correctly:

You should create an admin.py file inside your apps directory and then write the following code:

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)
