Django signals for beginners | How to use signals in Django

Tutorial on django signals for beginners
This video is an introduction to most commonly used signals in Django that every beginner should know. Learn how to use basic signals in Django : post_save, pre_save, m2m_changed, pre_delete
in an introduction, project based tutorial on Django signals. After watching this video, you'll understand how django signals work and you will be able to include them in your own projects!
I haven't found online a tutorial which would cover in one short video Django signals - so this is my attempt to help beginners get started on this.
Recorded with a fever, but hopefully still understandable enough :)

Awesome job in explaining how django signals work!! I was stuck in a project too trying to implement signals. Your video gave me a clear idea on how they work now... thanks a lot

[@et4493]

by far my favourite channel to learn Django. Django is pretty complex IMO, there's a lot of referencing back and forth but you do a great job of pointing it out and guiding us through it.

Hi Aashay! Thanks for the kind words. Django channels are on my list, but there are still a few videos I want to publish before. In the meantime you can check out Daniel Feldroy's video on Django channels. I haven't seen it, but Daniel is one of the leading experts in django. Link: th-cam.com/video/yizDiX0SOm4/w-d-xo.html

[@GiantsOnTheHorizon]

I may have read this wrong but, in the docs it seems like as long as you use the full "dotted" path in your INSTALLED_APPS, it appears that you don't need to use the default_app_config in your __init__.py file. Anyway, I love your channel! Thanks for all of the great content.
