Requirements

hiredis==0.2.0
redis==2.10.6
redis-extensions==1.1.1

Settings

• func_settings.py

  # -*- coding: utf-8 -*-
  
  import redis_extensions as redis
  
  def redis_conf(conf):
      return {
          'host': conf.get('HOST', 'localhost'),
          'port': conf.get('PORT', 6379),
          'password': '{0}:{1}'.format(conf.get('USER', ''), conf.get('PASSWORD', '')) if conf.get('USER') else '',
          'db': conf.get('db', 0),
      }
  
  def redis_connect(conf):
      return redis.StrictRedisExtensions(connection_pool=redis.ConnectionPool(**redis_conf(conf)))
  

• settings.py

  # -*- coding: utf-8 -*-
  
  # Redis Settings
  REDIS = {
      'default': {
          'HOST': '127.0.0.1',
          'PORT': 6379,
          'USER': '',
          'PASSWORD': '',
          'db': 0,
      }
  }
  
  try:
      from local_settings import *
  except ImportError:
      pass
  
  try:
      from func_settings import redis_connect
      REDIS_CACHE = redis_connect(REDIS.get('default', {}))
  except ImportError:
      REDIS_CACHE = None
  

Import

from django.conf import settings

r = settings.REDIS_CACHE

# r.set('foo', 'bar')

• Advanced Encapsulation

  • utils/redis/connect.py

    # -*- coding: utf-8 -*-
    
    from django.conf import settings
    
    r = settings.REDIS_CACHE
    

  • Usage

    from utils.redis.connect import r
    

Usage

• Redis Cook Book

Problems

• If conf not have db, will raise KeyError: 'db'
  • fix bug: KeyError for description_format #768
