    I've spent hours watching videos on signals to no avail. Dennis comes in and explains it in frickin' 13 minutes.

    I like that you talk meaningfully fast enough to make it impossible for me to listen at 2X speed.

    As far as I go deep within Dennis´ lessons, the more I learn. Haven´t ever found a so clear teacher about Django during my time of research in the net. Thanks a bunch man.

    Really superb video with simple and understandable instructions. Previously, I was scared by another other tutorial video that I was unable to comprehend the simple concept. Great Work.

    Thanks a lot. My signals were not working as I had installed my app using the app name only. But when I used the config file as you say the signal worked perfectly.

    Great tutorial. The Django documentation was a bit vague, especially with tying in the signals within the ready() method. This got me up and running.

    Why signals do not work because you need to register it. In order to register you need to update __init__.py file with default_app_config = 'app_name.apps.app_nameConfig' so you don't have to do it in settings.py
