old method to initialize redis model extenstion Usage:

REDIS_MODEL_CONF = {
 :fields => { 
   :integer => :to_i,
   :boolean => :to_bool,
   :string => :to_s,
   :symbol => :to_sym,

  :redis_key => [:string, :symbol],
  :redis_aliases => {
    :token => [:symbol]
  },
  # (default is true) if true all nil values will not be saved into redis,
  # there should be problem when you want to set some value to nil and same
  # it will not be saved (use false to prevent this)
  :reject_nil_values => false
