NameError uninitialized constant JobsController::Pagination using no gems in Ruby

Using Rails 6.1.6 and Rails 2.7.0. and am following an article for adding pagination in Ruby using no gems. I’m running into a NameError exception for my Pagination module. Not certain if the naming of the hierarchy in the module is incorrect.

Pagination Helper

module PaginationHelper
  def paginate(collection:, params: {})
    pagination = Services::Pagination.new(collection, params)

    [
      pagination.metadata,
      pagination.results
    ]
  end
end

Jobs Controller

class JobsController < ApplicationController

  include Pagination

  JOBS_PER_PAGE = 8

  def index
    @pagination, @jobs = paginate(collection: Job.all, params: page_params)
  end

Error Message
NameError Exception

I’ve tried restarting the server to no avail. Am I missing something in the Pagination module?

>Solution :

That should be include PaginationHelper in your controller.

Or rename the helper to module Pagination.
