Best way to load module/class from lib folder in Rails 3?

Question

Since the latest Rails 3 release is not auto-loading modules and classes from lib anymore, what would be the best way to load them?

Answer 1

If only certain files need access to the modules in lib, just add a require statement to the files that need it. For example, if one model needs to access one module, add:

require 'mymodule'

at the top of the model.rb file.
