`ClassName.constants` returning empty array in Rails app

Question

I\'m working on a Rails 3 app, and I\'ve got a hierarchy of classes in my lib folder, e.g.:

lib
├── assets
├── tasks
│   └── import.rake
└── imp         


        

Answer 1

Using @apneadiving's suggestion, I was able to fix this by adding this line to the beginning of my base.rb file:

Dir[Rails.root.join('lib/importer/source/**/*.rb')].each(&method(:require))
