Django post_save preventing recursion without overriding model save()

Question

There are many Stack Overflow posts about recursion using the post_save signal, to which the comments and answers are overwhelmingly: \"why not override save()\

Answer 1

the Model's .objects.update() method bypasses the post_save signal

Try this something like this:

from django.db import models
from django.db.models.signals import post_save


class MyModel(models.Model):

    name = models.CharField(max_length=200)
    num_saves = models.PositiveSmallIntegerField(default=0)

    @classmethod
    def post_save(cls, sender, instance, created, *args, **kwargs):
        MyModel.objects.filter(id=instance.id).update(save_counter=instance.save_counter + 1)

post_save.connect(MyModel.post_save, sender=MyModel)

In this example, an object has a name and each time .save() is called, the .num_saves property is incremented, but without recursion.
