Module: ActiveSupport::Autoload

Overview

Autoload and eager load conveniences for your library.

This module allows you to define autoloads based on ::Rails conventions (i.e. no need to define the path it is automatically guessed based on the filename) and also define a set of constants that needs to be eager loaded:

module MyLib
  extend ActiveSupport::Autoload

  autoload :Model

  eager_autoload do
    autoload :Cache
  end
end

Then your library can be eager loaded by simply calling:

MyLib.eager_load!
