I have modified application.rb to autoload my lib directory:

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

I have defined a module X::Y in the file lib/x/y.rb with a function execute(param).

In a controller (A::B), I call execute in this file by including the file and then calling the function:

require 'x/y'
results = X::Y.execute(param)

This works perfectly for a short while after the application is loaded but quickly I start getting the error:

NameError in A::B#index
uninitialized constant A::B::X

Does anyone know what I might be doing wrong here?

Thanks!

    I decided to move these into the model for ease.
