I have a Django app using DgangoChannels, Djangochannelrestframework. It establishes a websocket connection with ReactJS frontend. As channel layers I use Redis like that
CHANNEL_LAYERS = {
"default": {
"BACKEND": "channels_redis.core.RedisChannelLayer",
"CONFIG": {
"hosts": [("redis", 6379)],
},
},
}
Redis and Django runs in docker. My redis docker setup is
redis:
image: "redis:7.0.4-alpine"
command: redis-server
ports:
- "6379:6379"
networks:
- nginx_network
When I run my app on production server everything works for 5-8 hours. But after that period, if Django app trying to send a message via ws if falls with the error
ReadOnlyError at /admin/operations/operation/add/
READONLY You can't write against a read only replica.

I understand that it somehow connected with Redis replication, but no idea why if falls after period of time and how to fix it
I have the same error, the possible solution is here
Fix by adding command to docker and disable the replica-read-only config,
add this to your redis docker compose
command: redis-server --appendonly yes --replica-read-only no
then you could try to verify if the replica-read-only is disable usingredis-cli > config get replica-read-only command , if the result is no then it successful to disable.
I developed an e-commerce site on my local laptop and the project uses redis and when I run the project from localhost, it works perfectly using the following
r = redis.StrictRedis(host=settings.REDIS_HOST, port=settings.REDIS_PORT, db=settings.REDIS_DB):
REDIS_HOST = 'localhost'
REDIS_PORT = 6379
REDIS_DB = 1
Now, I am trying to deploy the project to python anywhere. I have installed the redis and started the server, changed localhost to myhost.pythonanywhere.com but when I run visit the site I get the following error:

I work on:
Ubuntu 14.04.1 LTS 64-bit
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Any idea how it fix?
It is not your mistake , it happened because of improper installation of Django.
My solution is go to the location where django folder is situated.
which is basically
/usr/local/lib/python2.7/dist-packages
From there remove the folder.
sudo rm -rf django
Reinstall Django
sudo pip install Django==1.7
or any version which u want.
Enjoy !!!
I have a Django application which saves a file in /opt/Webapp/userfiles/but Apache will not permit this.
In my settings file I have:
MEDIA_ROOT = os.path.join(PROJECT_ROOT, 'userfiles')
but I have also tried with
MEDIA_ROOT = '/opt/Webapp/userfiles'
The full error is:

Change permissions of directory with chmod and shown commands. Or change your directory. I don't think that /opt is the best place for such files.

I have upgraded my django version from 1.5.2(if i don't remember bad) to 1.6 and now when i execute my project on localhost i get this error:
IOError at /
[Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/httplib2-0.8-py2.7.egg/EGG-INFO/top_level.txt'

It looks like a Permission Error. Try to change the permissions with the chmod command (http://www.thegeekstuff.com/2010/06/chmod-command-examples/).
For example
sudo chmod -R 755 problematic_folder
