How to create a module in lib folder in Ruby on Rails?

Question

I want to create a module in /lib folder & access that form my controllers. There are several solutions available in different websites, but modules are not loading.

You need to add:

config.autoload_paths += %W(#{config.root}/lib)

to your config/application.rb

And then:

require 'file_name'

in your controller. That works for me (Rails 4).
