4 years ago I got into IT because of you and surprised to see such less subscribers. you deserve a lot more.

Would be cool, if you could go deeper into how to structuring larger applications in a sailable and maintanable way. Including folder structure, business logic, validation... There are a lot of beginner tutorials. But it is much harder to find advanced tutorials.

Thank you for the help understanding signals! helped me out a lot. caught you slipping there tho at 17:02.

This is a very good tutorial, i would suggest you make it a series whereby you cover this kind of Django specialized concepts that are not usually covered in general tutorials. You pick them same as you picked signals and focus only on them per video. it would have been nice if you also cover m2m signals. Thank you.

Your explanation is very clear and straightforward to understand the logic. Thanks

Deep drive into full stack testing. Testing views, models, forms, etc.

Thanks. Thank you a lot. Thank you so mush. I have searched for two weeks for that, and finally find it and understand it. Thank you

I would like to see a deep dive into Channels because there seems to be little to no in depth explainations with the same way you present the details which is so unique and understandable

best explaination

Thank you very much man.

thx very much for subtitles

You are amazing. Thank you very much for the effort of teaching in very simplified way. Iam learning a lot from you. Thank you.

Best signals introduce for beginners ever 🎉😊

he is not a teacher, he is more than a teacher the way he teaches is awesome

Very helpful video

Very good and simple explanation.

Thankyou justin this is helpful

I understood how to use signals. That was a great explanation. Thank you. I'd like to place a practical question, if I may: I don't see why I would implement the behaviours on BlogPost using signals. Why not override the save method (for instance) on the model itself? It seems to me a much cleaner workflow for the example you presented. By overriding the method I'd have all the class related behaviour in one place under the umbrella of the class itself. I can see the utility for signals when dealing with a layered architecture and I don't want to inject code of a higher layer into a lower layer (which shouldn't know anything about its clients). The first example, triggering actions based on User creation, matches perfectly this scenario. I know your intention is to bring a didactical example to showcase the signals. I'm just elaborating on this on my side. Congrats for the great content!

About adding slugs to an instance, doesn't using signals seems a little bit overkill, I mean I'm always overriding the save() method in the Model, check if there's a slug on the instance, if not, slugify the title, add it as an attribute to the instance and call the super save

thanks for sharing this idea. you help me a lot!!!!

Thanks a lot.. Well clear explanation

Very good explanation.

Thanks my dear brother... Very good examplez

great tutorial, keep it going :D

Thank you bro for the amazing content)

Hi sir, Big fan of you and your tutorial. I have a request on Django framework. I have searched KZfaq and google about booking system with Django. But I did not get proper instruction how to do that. If you upload tutorial about that, it will be very grateful. Thank you, sir. 🥰🥰🥰

thanks

Please make a video about business logic in django. Some people believe that business logic should be in the Models

Great job, thank you

Here is some challenge i guess How to pass additional data to the signal For example we have default user model and while user registration we are also asking for some additional data like phone number, DOB, etc ..these additional data needed to pass to the signal

25:22 He says, "actually that doesn't cover all types of delete". That means that when you delete multiple objects(using multiple checkboxes in django admin), def delete () would not work there. It only works on single object. Hope this clears someone doubt.

im still confused as a first timer learning django but im less confused compared to 45 minutes ago thanks

awesome video

Can you cover Signals for foreignkeyfield

Great Tutorial! Helped me achieve some King of business logic in an Invoice and Stock Management System. But How To notify user in a django template in realtime like maybe the user x has been deleted or Added ?

got question. Instance is not given an ID until you save it. But how is the condition working in blog_post_pre_save() model?

21:25 Would be good if you included that video link in description. Couldn't find it.

can we use django signals to send notifications also

So Justin Bro, This acts like a trigger that is used in relational SQL tables servers like Mysql, PostgreSQL and etc

Please help me, signal m2m_changed post_remove does not work for me

Thank you for the great content. Will django signal works if i have to give access to students which was registered by teacher in school management system. Haven't seen tutorials taking about this. I would be very grateful if you give some idea. Thank you 🙏🙏🙏🙏

how can I implement django signals in docker?

Why signals work only when we put them in the models.py file?

Never dissappoints like always

Nice tutorial as always 😉 Thanks for sharing. I have one query regarding usage of signals in a distributed environment. Let's say we are running django in multiple processes via docker or something and these signals are run inside the same process in which the model was created. So how to handle scenarios for failover. Like if the process got crashed without executing let's say the post save signal. And when it restarts, the signal is lost but model got saved. Any ideas on these scenarios?

Is this same process,if our project is live

NSFW warning at 17:00 xD

hey.. sir is it work django with mysql database

Thanks for the tutorial. Any chance you update your DRF course on Udemy?
