django-channels

I've got a django channels consumer communicating with a client. I've got a view from an external API that wants something from the client. From this view I want then to tell that consumer to ask a request to the client through his socket. I'm currently exploring django rest framework but I can't find a way for now to directly ask anything to that consumer. Well I've got an idea but it involves creating another socket and communicate through channels' channel. But I wish I could get rid of this overload. Ken4scholars From your reponse in the comments, it seems you want to send a message to the

I am trying to use Django channels to establish a websocket connection with the browser. The websocket fails to connect with the server: [2017/01/23 23:51:50] HTTP GET / 200 [0.03, 127.0.0.1:60445] [2017/01/23 23:51:51] WebSocket HANDSHAKING /chat/ [127.0.0.1:60451] [2017/01/23 23:51:56] WebSocket DISCONNECT /chat/ [127.0.0.1:60451] Javascript used for websocket: socket = new WebSocket("ws://" + window.location.host + "/chat/"); socket.onmessage = function (e) { alert(e.data); }; socket.onopen = function () { socket.send("hello world"); }; // Call onopen directly if socket is already open if

I am trying to create a face detection web application written in django. The app works this way. The user navigates to the url The camera starts on the client machine Each frame is then sent to the server for face detection Processed frame is then displayed on the web page I understood I could not use opencv VideoCapture because, it only works on the server side. When I read online people asked me to use javascript and specifically webRTC to start live stream on the client side. So I found this tutorial which explains how to start webcam on the client machine with javascript. Now my question

I'm trying to make a page which shows live-updating data to the client. The rest of the site is built with Django, so I'm trying to use Channels for this. The data I am displaying is saved in both a JSON file and a MySQL database for further calculations in other parts of the site. Ideally, I would like to display the latest data received (that is, when the file updates) to the client as it is received. And even though as I understand Channels are built exactly for this purpose, I am having trouble doing it. I have tried sending multiple requests from the client-side with delay and loops in

I've got Django Channels 2.1.2 set up in my Django app by following a tutorial and now need to set up a notification system for new messages. I want to do this in the simplest way possible. I can do it via browser push notifications, but I don't want to do it like that. I want it to be like Stack Overflow, where there is a red number representing the instance of a new message. One answer on here said For notifications you only need two models: User and Notification . On connect set the scope to the currently authenticated user. Set up a post_save signal on your Notification model to trigger a

I would like to upload files and images using django-channels but i don't have any idea where to start. Seems like there is not much documentation about websockets and file/image uploads. Any ideas? I also faced the same problem and I solved it by uploading the the Image/File in S3 bucket. we just need to decode the base64 code and upload the file and return the URL to websocket. We can also provide preview of the image by providing the file type. def file_upload(self, data): # Convert decode the base64 data file = base64.b64decode(data['data']['content'].split(',')[-1]) filename = data['data'
