def config
  @_config ||= ActiveSupport::InheritableOptions.new(superclass.respond_to?(:config) ? superclass.config : {})
end

#config_accessor(*names) ⇒ Object

Allows you to add shortcut so that you don’t have to refer to attribute through config. Also look at the example for config to contrast.

class User
  include ActiveSupport::Configurable
  config_accessor :allowed_access
end

user = User.new
user.allowed_access = true
user.allowed_access # => true
