def mget(name, objects = [])
  return [] if objects.nil? || objects.empty?
  raise "Field name Error" if !redis_objects.keys.include?(name.to_sym)

  keys = objects.map{ |obj| obj.redis_field_key name.to_sym }

  self.redis.mget keys
end

#value(name, options = {}) ⇒ Object

Define a new simple value. It will function like a regular instance method, so it can be used alongside ActiveRecord, DataMapper, etc.
