django.core.exceptions.ImproperlyConfigured: "server" must be an iterable or string

[mikeedwards]

When I pass a value of "server" that is type unicode instead of str I get:

  File "/Users/Mike_Edwards/.virtualenvs/emojicatch/lib/python2.7/site-packages/redis_cache/backends/base.py", line 84, in get_servers
    '"server" must be an iterable or string'
django.core.exceptions.ImproperlyConfigured: "server" must be an iterable or string

More specifically, the django-environ app is what's passing the value in as unicode but it seems like that should work either way.

It looks as though a recent change to get_servers uses isinstance narrowly and only allows values that are type str:

I'm using:
python 2.7.6
Django 1.8.2
django-environ 0.3.0

@mikeedwards – The latest release should have fixed that issue, let me know if it works for you.

@sebleier yes, I update to django-redis-cache==1.2.1 and works fine. Thanks.

@emilioramirez – Great! Thanks for testing.

Seems like this issue may be back in 2.1.0?

Same for me 2.1.1.

Found that in following configuration REDIS_URL is empty or not configured. So, works fine.

CACHES = {
    "default": {
         "BACKEND": "redis_cache.RedisCache",
         "LOCATION": os.environ.get('REDIS_URL'),
    }
}
