Django signals for new entry only
Checking for instance.id is a nice way of determining if the instance is "new". This only works if you use ids that are auto-generated  by your database.
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
