Error "NameError, uninitialized constant" after changing controller code

Question

Recently, I was able to organize my code by combining everything into folders.
I had a problem with the same group name as for my controller group in the app/ directory and for my module in the lib/ directory, but I was able to fix it as follows:

Rails: name for library module and controller group?

I also know that whenever you change your lib code, you need to restart the rails server, which suits me completely.

But after a recent reorganization, every time I change the code in the controllers, I get the following error:

 NameError at /admin uninitialized constant Admin::PagerDuty 

and to resolve it, I just restart the server!

Any advice ?!

EDIT: STRUCTURE:

The controller main_controller.rb is under app/controllers/admin

 class Admin::MainController < ApplicationController end 

The main_helper.rb is under app/helpers/admin

 module Admin::MainHelper require "admin/pager_duty.rb" def pager_duty pagerduty = Admin::PagerDuty.new() @on_call = pagerduty.on_call() @counts = pagerduty.open_incidents() end end 

lib pager_duty.rb is under lib/admin

 module Admin class PagerDuty .... end end 

Answer 1

Try to change

 require "admin/pager_duty.rb" 

to

 require_dependency "admin/pager_duty.rb" 

in your module.
