Question

I’m using Django’s post_save signal to send emails to users whenever a new article is added to the site. However, users still receive new emails whenever I use save() method for already created articles. How is it possible to receive emails only when NEW entry was added?

Thanks in advance

Answer 1

The post_save signal receives a boolean created argument which indicates if the saved instance was created.

def my_callback(sender, **kwargs):
    if kwargs['created']:
        print('Instance is new')
