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.

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.
