具有可编辑外键关系的Django Inlineformset

Question

I'm trying to create a formset of related objects, where the relation itself is also an editable field.

Let's say we have a models.py like the one below.

from django.db import models

class Author(models.Model):
    name = models.CharField(max_length=45)

class Book(models.Model):
    name = models.CharField(max_length=45)
    author = models.ForeignKey(Author)

Is there a good, pythonic way to create a formset of all Books by a certain Author, and be able to change the Author of any of those books? This would be a particularly useful way to fix any errors in the foreign key relations.

My first instinct was that inlineformset would solve this for me, but I can't seem to get the Author of each book to be an editable field, even when I use custom forms.

Answer 1

using modelformset_factory will do the trick. (pulled from my comments here for completeness of the systems question/answer model)
