[@Felipedotcom]

Really nice tutorial!!. It covers a lot of stuff and the examples are great. I would have appreciated to get to know a little better how it works with the models, but anyway. I'm currently doing a django project using DRF and I just realised that if I want real time applications I would have to use something like django channels. The question is, should I rewrite all my code to send data through websockets?, or maybe just using the websocket to check if there are new items, send a response to the frontend like saying "Hey there are new items, fetch again using REST" would be a good approach? Thanks!

[@medoabdin480]

you are really amazing bro. actually, you have a nice illustration to simplify the idea, thanks a lot

[@jurajnajiva]

If you are trying to put this into production by using uvicorn and are getting the following error "Django can only handle ASGI/HTTP connections, not websocket." its because you should call get_default_application() from the channels.routing instead of get_asgi_application() from the django core. (ps: You have to call django.setup() before)

[@orkhanrustamli2039]

Hi. Thanks for amazin tutorial, really helped me understanding basics of Channels. The only thing stays confusing for me is Redis usage in Channels. What is its purpose? Just connecting several instances? But how it accomplishes it? There is no much information on documentation of Channels as well.

[@tonydias4290]

CONGRATULATIONS!! You rock. It would be perfect if you make a video with channels with DRF, redis and celery (as backend) and react.js as frontend. Like full application, profile and so on. :) THX!!!

[@CodingEntrepreneurs]

Thank you!! Channels replaces the need for celery (actually I’m pretty sure they don’t play well together at all). Love the suggestion. What type of app would you want to see?

Hi, Thank you for your great tutorial, I have a question. I want to get some API data in the backend and send them to all of the web page visitors continuously. Say I want to show some stock market info to everyone visiting the web page. I know how to get the data from API, but I don't know how to send them to all every 5 second continuously without the frontend asking. how can I implement that efficiently? Thanks.

Great Tutorial. Thanks! How would it be for receive mobile connections (something like an REST Api), to create a chat on the Mobile Application ?

[@dalmasogembo7034]

You can try using ionic or react with the websockets in the frontend in JavaScript or typescript then do the normal URL routing in Django then match your frontend urls with the Django urls. Lack of stable internet slows me down from doing this

[@sayansanyal8259]

Hey there...I loved the video and a learnt a lot about the channels and redis. I was wondering what changes do I need to make in order to make the chatroom available to multiple users, more specifically I want something like that of a group chat where the users connected to a group will recieve their messages in real time. Any suggestions from your side would be very helpful. Thanks in advance ❤

If you're on Windows and you have problems installing channels with an error like: Microsoft Visual C++ 14 is required, Download Twisted from www.lfd.uci.edu/~gohlke/pythonlibs/#twisted. Choose the win32 one corresponding to your python version. For instance, I used Python 3.8; so I downloaded Twisted‑20.3.0‑cp38‑cp38‑win32.whl (Notice "cp38"). Once downloaded, navigate to the download folder in your command prompt and run 'pip install ' followed by the file u just downloaded. After this you can install channels or whatever.

[@ThePirateHistory]

Hello, thank you for the long-awaited lesson, I wanted to ask, I saw that you have projects in your projects, deplyoment, on digitalocean, apache was the server, why exactly? I for example through nginx, yes with the new version there there was a hemorrhoid, in a kind of caching of files, now caching is not established for the separate block, on type to store css, and so on, now it is installed in so to say in the parent block, that is stupid for all , as I did not try to expose only for the files, it does not work for them, I expose them to the parent block, caching works, but I found the solution to expose to the parent block as I said) but why apache?

[@CodingEntrepreneurs]

So you’re saying I should do a tutorial on deployment with Nginx? 👀

[@CodingEntrepreneurs]

Thanks. So you can create another consumer for this data, have your chat consumer send data to the other consumer that would do these kinds of updates (logs) that are user facing. Connecting to telegram would require api access and you’d have to use asyncio to await results from the api requests much like what we do with the database
