[英]Deploying django channels on heroku
I have created a standard django application with startproject, startapp, etc. and I want to deploy it on heroku.我用 startproject、startapp 等创建了一个标准的 django 应用程序,我想将它部署在 heroku 上。 When I was using gunicorn I solved the directory issue like so:
当我使用 gunicorn 时,我像这样解决了目录问题:
web: gunicorn --pythonpath enigma enigma.wsgi
with the --pythonpath option.使用 --pythonpath 选项。 But now I am using django channels and so it is daphne.
但现在我使用的是 django 通道,所以它是 daphne。 Is there an equivalent?
有没有等价物? I have tried everything but for the life of me I can't get the project to start.
我已经尝试了一切,但对于我的一生,我无法启动该项目。 I always get issues with the settings file, apps not loaded or another assortment of cwd-related issues.
我总是遇到设置文件、未加载应用程序或其他各种 cwd 相关问题的问题。
As given in the Heroku Django channels tutorial, I have tried:正如 Heroku Django 频道教程中给出的,我尝试过:
daphne enigma.asgi:channel_layer --port 8888
This led to a variety of module not found errors with asgi and settings.这导致了各种模块未找到 asgi 和设置的错误。
I also tried我也试过
daphne enigma.enigma.asgi:channel_layer --port 8888
This led to module not found enigma.settings errors.这导致 module not found enigma.settings 错误。
I also tried我也试过
cd enigma && daphne enigma.asgi:channel_layer --port 8888
Which led to Django apps not ready errors.这导致 Django 应用程序未准备好错误。
I also tried moving the Procfile and pipfiles into the project directory and deploying that subdirectory but once again I got apps not ready errors.我还尝试将 Procfile 和 pipfiles 移动到项目目录并部署该子目录,但我再次遇到应用程序未就绪错误。
I have now started temporarily using我现在已经开始临时使用
cd enigma && python manage.py runserver 0.0.0.0:$PORT
But I know that you're not supposed to do this in production.但我知道你不应该在生产中这样做。
Try this:尝试这个:
Procfile档案
web: daphne enigma.asgi:application --port $PORT --bind 0.0.0.0 -v2
chatworker: python manage.py runworker --settings=enigma.settings -v2
settings.py设置.py
