Re: Call a custom python function during each model save

[Andy Mikhailenko]

Try signals[1], namely pre_save[2]. I would stick to this way instead
of overriding model's save() method.

[2] 
http://docs.djangoproject.com/en/dev/ref/signals/#django.db.models.signals.pre_save

Re: Call a custom python function during each model save

[ANIL KARADAĞ]

you can override model save method:

for example

class Student(models.Model):
name = models.CharField(blabla)

def save(self, *force_insert=False*, *force_update=False*):
# call spesific python method
# operations
super(Student, self).save(force_insert=force_insert,
force_update=force_update)
