One way is to hook into your inline model's `pre_save' signal:

from django.db.models.signals import pre_save
from your_app.models import YourModel

def callback(sender, **kwargs):
    # 'instance' is the model instance that is about to be saved,
    # so you can do whatever you want to it.
    instance.field = new_value

pre_save.connect(callback, sender=YourModel)

But I'm not sure why you can't just override the save method, which is almost always a better approach.
