The traceback indicates it cannot access the redid cache. How did you install Django-ca, what version, which Python version? And in this case, what redis version are you using?

[raydoom]

I use docker ,follow the doc from https://django-ca.readthedocs.io/en/latest/docker.html

[root@localhost ~]# docker ps

Hi @raydoom ,

I found the problem: There is a mistake in the documentation, the DB value should be db. Change localsettings.yaml like this:

  CACHES:
      default:
          BACKEND: django.core.cache.backends.redis.RedisCache
          LOCATION: redis://redis:6379
          OPTIONS:
-             DB: "1"
+             db: "1"

  # django-ca will use Celery as an asynchronous task worker
  CELERY_BROKER_URL: redis://redis:6379/0

This should solve the problem!

I also just added a test script to test that everything can connect properly, making such mistakes impossible in the future. :-)

kr, Mat

[mathiasertl]

@raydoom I think the issue is solved. If you still have issues with connecting to redis, please comment here. If you experience other issues, please don't hesitate to create a new issue!

I'll leave this issue open for a week unless there is negative feedback, please feel free to close the issue if everything works for you.

kr, Mat

[raydoom]

it work ,thanks
