You could customize the Admin Book Creation Form's save() method to check
for X number of books an author already has.

Note: I have very limited experience customizing the Admin application and
have only used this method through a normal Form.

limit number of related instance for m2m field in django-admin

[vijay shanker]

hi
is there any way to limit the number of instances that can be attached
to a m2m field.
e.g
author = models.manytomany(Book)

i want to limit the max number of book objects that can be attached to
author.
How to go about this.
