Django Channels & WebSockets Oversimplified

[@DennisIvy]

Don't forget to check out my Complete Django course: dub.sh/tukI9mp

[@kalok2206]

This tutorial not work on Channels v4.0.0 Should be force to install v3.0.5 : > python -m pip uninstall channels > python -m pip install -Iv channels==3.0.5 By the way. This tutorial is best I found in youtube

[@willsanchez5735]

THANK YOU FOR THIS!!!!

[@strikelight1041]

thank you so much

[@truelife9057]

Really thank man!

[@siddharth5444]

from v4.0.0 of channels, ASGI in development mode does not work. You will have to install daphne as well python -m pip install -U daphne

[@hxxzxtf]

why does it not work on v4? what changes are to be made?

[@philosoraptor8728]

Despite the language barrier, it is the best material I could find, and it is very well explained. You made it look very easy what is breaking my head a week ago, Good job, thanks.

[@johnnygarcia7297]

This is why i love this channel, no losing time straight to the point step by step

[@CharlesBLim]

Boy that was intense, oversimplified indeed but my mind gets overloaded with this advance lesson on Channels and websockets. Thanks

[@marcinknap3802]

You are literally reading my mind. Seriously Dennis, thank you for your work.

[@wolfred10]

This tutorial needs an update, you have to include the package "daphne" for it to work

[@ChiragShrestha-s8z]

I love the content. Its fast, doesn't waste my time and particularly covered everything I needed. Sleek thanks.

[@radeonblue1816]

Thanks for manually typing the code and showing to us how this works. 8:38 was the best time for me when I saw the message on console. Based on documentation I had pasted the code as they said but it hadn't worked. Fortunately, Everything worked when you showed writing the code by yourself rather then copy pasting it.

[@BehruzbekOtayev]

thank you for helping make Django more accessible to beginners. Keep up the great work.

[@geetcyberlab5108]

I haven't watched the video yet but am rating it a 5-⭐ keep up the good missionary work Denis...

I'm waiting for the full chat app tutorial! Love your channel! I've learned so much and yet, so much more to learn!

[@DarkOceanShark]

I was just learning WebRTC so that I can send client side camera feed to the server. By doing so, I will be able to apply machine learning on that feed and identify facial expressions in server-side. I came across Django channels which can be used for this purpose along with WebRTC. Now you have uploaded a video on Django Channels! I love your channel and this video is gold to me. You gotta be reading my mind haha. If you can could you like make a video on what I am trying? Sending client side webcam feed to server and processing that feed in server-side. Thank you!

[@tanaysheth8601]

It's a good idea! Django with computer vision(like Opencv) is really one of the greatest projects to do.

[@DennisIvy]

I just did a video on my channel on a django video chat application and in that video I mentioned that I planned to do a video with channels, websockets & webRTC. So keep an eye out for it ;)

I now understand Django channels thanks to this video.

[@jpablomayorga]

Thank you very much, I'm new to the subject of django channels and I found your introductory explanation very good. Using redis as an in-memory database integrated with channels is very complex, you already published that video, I really appreciate the information you can share about it

u promised and fulfilled , thanks from egypt dennis♥️♥️

[@МихаилСлуцкий-м7г]

4:20 For some reason, my project didn't want to start without Daphne. (added: python -m pip install daphne) and it worked. Maybe because my version of djanga is different then in video. But after it i got the result "Starting ASGI/Daphne version" :)

[@zdenek394]

Had the same issue bro. I remember following the tutorial a while back and seeing the starting ASGI server message... now nothing ... I thought it was some small mistake, tried to solve it for hours.

[@CC-nz2oc]

Same problem. Thanks for solution bro

Or change the channels version to the 3.0.5.

[@aphelioschenik3162]

PLZ PIN THIS COMMENT OF @Shivam Athiya For those who are struggling like me to achieve this - Starting ASGI/Channels version 3.0.5 development server or If you cannot send messages, the problem is channels version. You have to change the channels version to the 3.0.5. The latest version of channels is 4.0.0 and it seems not to be working. So do: pip install channels==3.0.5 or change the version in your virtual environment to: channels==3.0.5 thanks to this guy - @Szymon Budziak

[@imPxLxs]

I read channels duc 1week before I can remember in the duc they said all channel layers method are Asynchronous But here you use Async_to_sync Why? Already your code wasn't Asynchronous I didn't see any await or async on the code If I have mistake , say me

[@xiao_wang1212]

Thank you very much! This helped me a lot, but I encountered a problem while working on the project. I have a complete pygame project, and I suddenly wanted to know if I could combine it with Django. I asked chatgpt, and he said yes and gave me websocket-related methods, but problems would occur every time I executed it. I would like to ask if it is feasible to combine Pygame and Django?

"WebSocket is already in CLOSING or CLOSED state" this is my problem how to solve

[@leandromarquez9257]

Could you solve it?

[@hereisfahad]

You have to wait for the socket connection to complete before sending the message. It should look something like this: function sendMessage(message) { chatSocket.send( JSON.stringify({ message: message, }) ); } setTimeout(() => { sendMessage("test") }, 5000)

[@mueezkhan280]

how can we differentiate between the messages sent from multiple channels in a group ? simple use case example: in whatsApp, in a conversation, in user1's view (consumer web instance) his messages gets displayed on the right side with green background, while in user2's view (consumer web instance) his messages gets displayed on the right side with green background.
