We use redis with django-rq to manage queues on our project. Heroku has recently forced upgrades to Redis 7.0.11 and that requires TLS. Per their docs we need to set 'ssl_cert_reqs'=None in order to make sure redis is using TLS but not looking for a cert.
CACHES = {
"default": {
"BACKEND": "django_redis.cache.RedisCache",
"LOCATION": os.environ.get('REDIS_URL'),
"OPTIONS": {
"CLIENT_CLASS": "django_redis.client.DefaultClient",
"CONNECTION_POOL_KWARGS": {
"ssl_cert_reqs": None
},
}
}
}
Setting the above in my project's settings.py results in the following error:
TypeError at /login/ __init__() got an unexpected keyword argument 'ssl_cert_reqs'
Other settings like "max_connections": 5 don't cause an error. I've been searching and I haven't seen anyone else with this issue. Has anyone else run across this issue and hopefully a fix?
We're using:
Django==2.2.28
django-redis==5.2.0
django-rq==2.8.1
redis==4.5.5
rq==1.15.1
It also fails on another build we have:
Django==3.0.14
django-redis==5.2.0
django-rq==2.8.1
redis==4.6.0
rq==1.15.1
We've tried configuring our project with multiple builds of Django, django-redis, django-rq, redis, and rq with no luck.
