Question

I have the requirement that whenever there is a model get’s added/changed/deleted, it should send a mail notification. The content will be more like the django_admin_log entries. I just need to extend this functionality in my model to send the mail. Any suggestions?

Django_log_admin will only track changes made in the admin interface. If the model is changed anywhere else, it will not update the log. However, if you are OK with just admin changes, then you can use a combination of django_log_admin and the post_save signal to do the trick. Put this in your management.py:

from django.db.models.signals import post_save
from django.dispatch import receiver
from django.contrib.admin.models import LogEntry
from django.core.mail import mail_admins
from django.template.loader import render_to_string

#will be triggered every time a LogEntry is saved i.e. every time an action is made.
@receiver(post_save, sender=LogEntry)
def send_notification_email(change, **kwargs):
    mail_admins(subject="model %(model) has been changed by %(user)" % 
                            {'model':change.content_type, 'user': change.user},
                message = render_to_string('change_email.html', { 'change': change }) )

note to self: wow, django really includes all the batteries 😀
