Django restrict input in the admin

Question

I'm wondering how can I retrict the input of a field in the admin to only numbers and a max of 10 digits. The "max of 10 digits" part is confusing.

The model field is this one:

id_student = models.PositiveIntegerField(primary_key=True)

How can I make sure that in the admin it gets a max of 10 digits? I'm kind of lost in the docs and imagining weird ways to achieve this, I bet there is a simple way.

EDIT

Tried adding max_length=10, doesn't work:

id_student = models.PositiveIntegerField(primary_key=True, max_length=10)

Ok what I did that worked was using from django.core.validators import MaxValueValidator:

id_student = models.PositiveIntegerField(primary_key=True, validators=[MaxValueValidator(9999999999)])

Cheers.

I think max_length=10 should do the trick for you.

What happens when you try to enter more than 10 digits in the admin after using this? – WutWut Jun 17 '15 at 11:23
