django-redis-cache 0.9.7

Redis Cache Backend for Django

A simple Redis cache backend for Django

Changes in 0.9.0

Redis cache now allows you to use either a TCP connection or Unix domain socket to connect to your redis server. Using a TCP connection is useful for when you have your redis server separate from your app server and/or within a distributed environment. Unix domain sockets are useful if you have your redis server and application running on the same machine and want the fastest possible connection.

You can now specify (optionally) what parser class you want redis-py to use when parsing messages from the redis server. redis-py will pick the best parser for you implicitly, but using the PARSER_CLASS setting gives you control and the option to roll your own parser class if you are so bold.

Notes

This cache backend requires the redis-py Python client library for communicating with the Redis server.

Redis writes to disk asynchronously so there is a slight chance of losing some data, but for most purposes this is acceptable.

In order to use redis.connection.HiredisParser parser class, you need to pip install hiredis. This is the recommended parser class.

Usage

1. Run python setup.py install to install, or place redis_cache on your Python path.

2. Modify your Django settings to use redis_cache :

On Django < 1.3:

CACHE_BACKEND = 'redis_cache.cache://<host>:<port>'

On Django >= 1.3:

# When using TCP connections
CACHES = {
    'default': {
        'BACKEND': 'redis_cache.RedisCache',
        'LOCATION': '<host>:<port>',
        'OPTIONS': {
            'DB': 1,
            'PASSWORD': 'yadayada',
            'PARSER_CLASS': 'redis.connection.HiredisParser'
        },
    },
}

# When using unix domain sockets
# Note: ``LOCATION`` needs to be the same as the ``unixsocket`` setting
# in your redis.conf
CACHES = {
    'default': {
        'BACKEND': 'redis_cache.RedisCache',
        'LOCATION': '/path/to/socket/file',
        'OPTIONS': {
            'DB': 1,
            'PASSWORD': 'yadayada',
            'PARSER_CLASS': 'redis.connection.HiredisParser'
        },
    },
}
