How to set up a maximum value in a Django DurationField?

I have a Django models with a DurationField. I would like that the users cannot put a value over 00:09:59. Unfortunately I could not find any information to do this in the doc : https://docs.djangoproject.com/en/4.1/ref/models/fields/#durationfield

>Solution :

You can add validators for that.

It will look something like:

DurationField(
    validators=[MaxValueValidator(datetime.timedelta(minutes=10)]
    )
