Iam working in django 2 with websockets inorder to pass the response to and fro a game server.Can anyone suggest the method or the correct flow for complete the communiction task between server and django through websockets?
If your server is already set up in django then django-channels would make sense. Websocket consumers in django channels have full access to your django ORM and your other views in django can issue messages (over channel groups) that can be used to inform the open websocket connections of changes they need to stream to the user.

I'm trying create a real-time chat app with Django and Vuejs. I would like to use django-rest-framework for this but I don't know how to make it real-time. I have used django-channels before but I'm curious if I can use only django-rest-framework as an alternative or maybe integrated it with django-channels.
You don't have to integrate them, because django channels are sending and accepting json data to websocket, as your rest framework api does. Rest framework is made for api, django channels for websockets, they won't have nothing in common cuz they have different implementations. The only thing you could consider integrating is rest framework auth inside django channels see: How do you authenticate a websocket with token authentication on django channels?
I also am a beginner but from what I know.. rest framework isn't suitable for "real-time" working of web-application cause it can't make a 2-way connection (like.. send data to other memebers in group without them making a call to it) for this purpose django channels is a better medthod cause its making a websocket connection.
do let me know if i m wrong.
I am working and I need your help. I am working on a website with Django with DRF on the backend and react on the frontend. I need a way of sending api data to the client whenever any changes are made. The data is only coming from the database, the client is only viewing the progress. What options do I have to acheive. I need it to handle a large number on people. Say 20 000. Please your help will do a lot for me.
You have two options:
Websockets. See Django-channels for Django implementation, on React side you will have to setup Websocket connection to your Django and listen for messages.
Use long polling, or periodic polling of data. Basically this is a process when your React app sends requests to backend periodically or makes a request that lasts forever.
Is there a way to connect django and a tcp server built with asyncio?
I have a TCP server that should maintain long-lasting connections with clients, but I want to integrate it with Django so that a user can send data over the TCP server based on forms from Django
I've heard of celery, but I do not know if it would be suitable for this application
My current idea is to put a temporary tcp client in the django code that receives posts, and have it send data to the tcp server. I would prefer not to do this because I would have to add more special cases to the TCP server in order to recognize that data is being sent from Django and not one of its other clients
Try aiohttp-wsgi. It offers a WSGI bridge for asyncio, on top of aiohttp, so you can process Django requests within your asyncio process.
Note that, when using Django as a web framework, the model instances lifecycle is usually not a problem because objects live only as long as the view that creates them. When using Django as a service (outside Django HTTP Requests) this doesn't happen, and you need to synchronize access to model instances carefully. This involves avoiding usage of cached/older instances to do modifications, and refreshing model objects anytime other process (ie Django views, or other service code) might have changed them. Django CRM does not guarantee uniqueness of model objects that represent the same database record.
I have a social networking kinda an app in Django and I wanna integrate real-time notifications and messaging functionality in my app.
my friends could build a tornado app but I wanna basically connect them together (my guess are I have to make a REST API correct me if I'm wrong)
how can I do these kinda tasks from Django
Authenticate automatically to a WebSocket(tornado) as I logged in my
django app
import all of my friends
send tornado signal to send notifications if the user didn't receive a message
things like that
how do I do stuff like that.
(BTW I don't wanna use django channels as it's fairly new)
You can use a message broker library like ZeroMQ or RabbitMQ to help them communicate with each other (The Django instance and the Tornado websockets component).
They provide several message architectures like server-client or publisher-subscriber.
I'm trying to find a way of sending data to my web server on Spring framework from Django which controls actions of tensorflow.
If Spring server send a request, is it possible to send a output from Django?
If you have experiences like this, please give me some tips.
You can simply make an HTTP request to your Django server, respond with JSON, and then parse that JSON into a Java class using a library like jackson.
Alternatively you can use a shared database where Spring simply uses JDBC to access the data you are trying to reach.
