Override update method for a queryset - Django

问题

How can we change the default process of update method for a queryset in django as it does not call save method for each object. And since i have overridden the save method, i need it to be called each time the object is changed. I looked for django doc but this is just for get_query_set, Is there is something similar for update method also.

Thanks

This worked for me

class MyQuerySet(models.query.QuerySet):
    def update(self, *args, **kwargs):
        # here queryset update method overridden
        pass

class NewManager(models.Manager):
    def get_queryset(self):
        # this is to use your custom queryset methods
        return MyQuerySet(self.model, using=self._db)

class MyModel(models.Model):
    objects = NewManager()
    myfield = models.SomeTypeOfField(**kwargs)
