Creating models from lib directory in Rails 4 - ruby-on-rails

Question

I have a file lib/stock_reader.rb in which I'm trying to create a model like so:
module StockReader
def self.create_company_reports(company_data)
CompanyReport.create(name: company[:name])
end
end
In another file, lib/curate.rb, I call this method:
require_relative 'stock_reader'
StockReader.create_company_reports(company_data)
But I receive the error:
/Users/me/code/applications/curator/lib/stock_reader.rb:38:in `block in create_company_reports': uninitialized constant StockReader::CompanyReport (NameError)
from /Users/me/code/applications/curator/lib/stock_reader.rb:37:in `each'
from /Users/me/code/applications/curator/lib/stock_reader.rb:37:in `create_company_reports'
from lib/curate.rb:12:in `<main>'
It seems that my lib directory is failing to recognize my model's existence in app/models/company_report.rb:
class CompanyReport < ActiveRecord::Base
end
I'm guessing this may be because the lib/ directory is being loaded before app/models, but I'm not sure.
I've looked at Accessing models from within the lib directory in a Rails 3 project but I can't see where my lib/ directory is being required in any rakefiles.

It happens when I test lib/curate.rb by running $ ruby lib/curate.rb
Well, that would explain it.
Ruby doesn't know anything about CompanyReport. Rails knows where to find your models because it has a ton of code that handles autoloading classes, but Ruby isn't Rails. If you want code to use Rails' features, you need to run the code in the "Rails environment."
There are a few ways to do this. If you want to run an arbitrary script (like lib/curate.rb) in the Rails environment, you can use the rails runner command:
$ bin/rails runner lib/curate.rb
The Rails console is also very useful for testing:
$ bin/rails console
Loading development environment (Rails 4.1.6)
irb(main):001:0> require Rails.root + "lib/curate"
It's pretty rare to use the ruby command in a Rails project, because usually you want to use Rails' features. You'll probably use the above commands a lot more often.

The problem is that CompanyReport class does not exist in the StockReader module where it's looking for it. To use the top level CompanyReport model preface the class name with ::
::CompanyReport.create(name: company[:name])
