Django connection to Redis

To connect Django to Redis, I have to open connection for each view:

import redis
cacheDB = redis.StrictRedis()
cacheDB.sadd("new_post", post.id)

Is there a way to create a single connection somewhere and import it into each view?

You can use django-redis, which allows using Redis as the backend for Django's cache framework. It supports connection pooling.

Basic usage:

# settings.py
CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

Then you can use it in your view code:

from django.core.cache import cache
cache.set('foo', 'bar')

For sadd you can use the raw Redis client:

>>> from django_redis import get_redis_connection
>>> con = get_redis_connection('default')
>>> con
<redis.client.Redis object at 0x2dc4510>
