Clear and concise. So many Django tutorials add fluff and muddy the waters when describing what to do when using Django.
Arthur C. Clarke: "Any sufficiently advanced technology is indistinguishable from magic."
This is simple and to the point, thanks.

My god I had been searching on how to send an update to slack when someone posts a message. I put an api call under the model's class and could not figure out how to only make it call when the model was saved. It was actually making api calls every time I ran manage.py migrate lol.
After two days of messing around in my code, placing the api call in defs and out of defs, in models and in views, etc etc.. this tutorial actually fixed it. Thank you so much!

[@muhsinkhalif3621]

Wow! thanks for the explaination other youtubers just glance over this signalling part(i think they just memorized it and not fully understand the underlying concept of send,receive signalling).

[@maahad767]

[@pratiksharma6522]

[@Brun69M]

[@yoga_with_atharva]

nice explanation👌

[@letccc]

Which VScode extension you are using for Django intellisense ?

[@nsulanov312]

Great 👍🏼 tutorial

[@AxmedShiimax]

Something still in my head, is it necessary to use signals while I want to create a user with profile or can I use after user creation form is a valid and saved then save with its profile?
Ur teaching style is awesome.
Thank you

[@tochimclaren]

The best practice will be to set a lot of the profile forms to blank listen to User model signal, create the user object and redirect to user Profile form to update it with information if that's what you are asking about.

[@shashanksharmadon4295]

Awesome...................

[@alimurtuza347]

i am learning from different source in that it make another signals file and define the signal there, while i am doing the same the content you provided in an another file signals.py but cannot connect my signals means it doesnot notify me when the request is finished

[@alimurtuza347]

it is bit confusion that we call that signal before the request is done

[@abdelrhmanahmed1378]

now function are called when ever save() called , so if i create new user then save is called then i will get a signal and my logic will get executed, when i update user then also save() get called ,then i also get a signal or not ?!!

[@defidelity]

Ykb 👍 thanks

[@mr2mato]

We only can use django signals in models.py, or we can use it in view.py too?

[@nomanabid7113]

you can separatly make signals.py where models and views exist. put the functionality there in signals.py. and do the necessary importing stuff like importing POST model from models.py and doing some functionality in signal.py

[@rathnaveljn423]

HOW TO perform some action when a dropdown menu is changed its item in DJANGO?

[@Zzzzzzzzzzzzzzzzzzzzr]

can signals be used on the frontend to instead send the message to the frontend instead of the terminal? Thanks

[@nomanabid7113]

yes

[@Nadeemkhan-fs2ys]

Great

[@mysteriousr7197]

In my project i need something like that..if i save "A" model. Then "A" models imagefield will be automatically added to the "B" models imagefield..can i do it using signal?

[@maahad767]

Yes. use something like this => "AnotherModel.object.imagefield = instance.imagefield"

[@lowkeygaming4716]

Hi. Do you have an idea why I'm getting an error with AUTH_USER_MODEL declaration when I register the signals module that I made in the AppConfig? It says that the model that I set is not properly registered?

[@nomanabid7113]

may be first create a super user

[@Didneodl]

Thank you for the great tutorial! Do you have any plans to make a tutorial about server side rendering with Django and React in the future? As ssr is required for websites focusing on SEO, I think it would be pretty much demanding!

[@mattfreire]

+Jaehong Park Thanks. Yes we do plan on making a tutorial on it in the coming weeks

[@davidmurphy563]

I wonder if anyone else here has experience with the Godot games engine which has a practically identical signals system.

[@shahzadisairaawan5079]

sir, can you please turn up your volume. all of your videos are very low in sound

[@pariszarka7959]

i want to use signals to send an email to the user everytime a user is registerd

[@nomanabid7113]

you can

[@shubhamnaik4205]

Sir, How to stop the "RecursionError" in post_save django signals ? I am calling the post_save signal after updating the post and changing the slug associated with the Post

[@chakradharpalaparthi4691]

Add the slug using pre_save and not post_save.
Because updating a Post in post_save will re-trigger the same receiver.

[@shaheerzaman620]

Good Video. The audio is too low in all your videos. Please make it louder.Thanks.

[@aayushdadhich1822]

as simple as that.
