Module just doesn't get loaded in the Model [Rails]

Before you marked this questions as duplicated, I've checked this other very related questions: 1, 2, 3, 4 and 5, and basically, all of them is the same way to load the lib modules, but User still keeps throwing an error.

models/user.rb

# This line throws an error:
# cannot load such file -- my-project-root/lib/model_with_properties.rb
require "#{Rails.root}/lib/model_with_properties.rb"

class User < ActiveRecord::Base

    # This line throws an error:
    # uninitialized constant User::ModelWithProperties
    include ModelWithProperties
    ...

end

lib/model_with_properties.rb

module ModelWithProperties

  # Some functions

end

config/application.rb

require File.expand_path('../boot', __FILE__)

require 'rails/all'
require 'yaml'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Project
  class Application < Rails::Application

    # Do not swallow errors in after_commit/after_rollback callbacks.
    config.active_record.raise_in_transactional_callbacks = true

    # Load the lib folder, a thousand times
    config.autoload_paths += %W(#{config.root}/lib)
    config.autoload_paths += Dir["#{config.root}/lib/**/"]
    config.autoload_paths << "#{Rails.root}/lib"
  end
end

What am I missing?

Another useful information:

julian$ rails r 'puts ActiveSupport::Dependencies.autoload_paths'
    Running via Spring preloader in process 38445

Answer

Big thanks to @jvillian, I was using RubyMine and I assumed the file extensions were hidden, and all that matter was the Ruby Icon on the IDE. Actually the .rb extension was missing.

In console, do Dir["lib/**/*.rb"] to make sure the file is actually there. Once you fix that, try removing the require statement in user.rb (as @Stefan suggests). Not altogether necessary, but require statements can sometimes mess with AutoLoading.
