$redis global variable with ruby on rails

Question

I am using redis as a read cache. I have created an initializer

config/initializer/redis.rb

$redis = Redis.new(:host => ENV[\"REDIS_HOST\"], :port =&         


        

Answer 1

A more namespaced option to replace your global variable, you can create a method in a module

module Caching
  def self.redis
    ... initialize/memoize/reconnect here...
  end
end

You than then call it with:

Caching.redis
