问题 I'm currently running a Django (2.0.2) server with uWSGI having 10 workers I'm trying to implement a real time chat and I took a look at Channel. The documentation mentions that the server needs to be run with Daphne, and Daphne needs an asynchronous version of UWSGI named ASGI. I manged to install and setup ASGI and then run the server with daphne but with only one worker (a limitation of ASGI as I understood) but the load it too high for the worker. Is it possible to run the server with

问题 Below is a full trace of the error. Please let me know what could fix this issue: (env) C:\Users\LENOVO\Desktop\SD\backend>python manage.py runserver Watching for file changes with StatReloader Exception in thread django-main-thread: Traceback (most recent call last): File "C:\Users\LENOVO\AppData\Local\Programs\Python\Python38-32\lib\threading.py", line 932, in _bootstrap_inner self.run() File "C:\Users\LENOVO\AppData\Local\Programs\Python\Python38-32\lib\threading.py", line 870, in run self

问题 I am developing an app using Django,I have deployed it on Google Cloud Platform initially using WSGI environment,now I have made addition in app and used channels due to which I have to shift from WSGI to ASGI, but I am getting errors while deploying to Google Cloud Platform when I use ASGI environment I got the error: respiter = self.wsgi(environ, resp.start_response) TypeError: __call__() takes 2 positional arguments but 3 were given I commented the all content of WSGI file when I want to

问题 I have added django.channels to a django project in order to support long running processes that notify users of progress via websockets. Everything appears to work fine except for the fact that the implementation of the long running process doesn't seem to respond asynchronously. For testing I have created an AsyncConsumer that recognizes two types of messages 'run' and 'isBusy'. The 'run' message handler sets a 'busy flag' sends back a 'process is running' message, waits asynchronously for

问题 I built a django-project and deployed it to production using Apache-WSGI combo. For that I had added the apache2.conf as shown below: WSGIScriptAlias / /home/ubuntu/MyProject/MyProject/wsgi.py WSGIPythonPath /home/ubuntu/MyProject <Directory /home/ubuntu/MyProject/MyProject> <Files wsgi.py> Require all granted </Files> </Directory> So this mean't all requests to my website first go to Apache, which then allows WSGI to come into play. So if I would switch off Apache, the website would not work

问题 I am using Ubuntu 18.04 LTS, Django 2.1, Python 3.6, Nginx, Gunicorn and the testing project I copied from is through this link: https://channels.readthedocs.io/en/latest/tutorial/part_1.html I deployed the ubuntu server based on the instructions here: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04#troubleshooting-nginx-and-gunicorn But i got the 404 error.

问题 I am building an online game, which uses Django channels 2.1.5 for websockets. I am able to build the connection between the client and the server, and also able to send data between them only inside the consumer class: from channels.generic.websocket import WebsocketConsumer import json from . import controller class GameConsumer(WebsocketConsumer): def connect(self): self.accept() print("Wohooo .. Connected to client!") self.render() controller.startTurn() def render(self, type="render",

问题 First of all, sorry for the long question, I hope a few of you have patience for this. TL; DR: How do I load django settings correctly in systemd? I am following this guide, Deploying Django Channels Using Daphne, so I can run some real-time apps (using WebSockets). Without nginx, and running from the command line the worker (python manage.py runworker) and interface (daphne), I can access the correct channels consumer class, as can be seen in the log below (these were triggered from a
