Controller Name Error - ruby-on-rails

Question

I have added a module to my application called Tokened.rb and added the include Tokened to my model. However, now when I try to load that model, I get a "NameError in TestingsController#index" error... I haven't included Tokened in my TestingsController, but not sure why I should or where I should put it.
My code:
testing.rb
class Testing < ActiveRecord::Base
include Tokened
end
My Tokened.rb module:
module Tokened
extend ActiveSupport::Concern
included do
after_initialize do
self.token = generate_token if self.token.blank?
end
end
private
def generate_token
loop do
key = SecureRandom.base64(15).tr('+/=lIO0', 'pqrsxyz')
break key unless self.class.find_by(token: key)
end
end
end
Finally, my testing controller:
class TestingsController < ApplicationController
before_action :set_testing, only: [:show, :edit, :update, :destroy]
# GET /testings
# GET /testings.json
def index
#testings = Testing.all
end
# GET /testings/1
# GET /testings/1.json
def show
end
# GET /testings/new
def new
#testing = Testing.new
end
# GET /testings/1/edit
def edit
end
# POST /testings
# POST /testings.json
def create
#testing = Testing.new(testing_params)
respond_to do |format|
if #testing.save
format.html { redirect_to #testing, notice: 'Testing was successfully created.' }
format.json { render :show, status: :created, location: #testing }
else
format.html { render :new }
format.json { render json: #testing.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /testings/1
# PATCH/PUT /testings/1.json
def update
respond_to do |format|
if #testing.update(testing_params)
format.html { redirect_to #testing, notice: 'Testing was successfully updated.' }
format.json { render :show, status: :ok, location: #testing }
else
format.html { render :edit }
format.json { render json: #testing.errors, status: :unprocessable_entity }
end
end
end
# DELETE /testings/1
# DELETE /testings/1.json
def destroy
#testing.destroy
respond_to do |format|
format.html { redirect_to testings_url, notice: 'Testing was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_testing
#testing = Testing.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def testing_params
params.require(:testing).permit(:name, :address, :signature)
end
end
What gives? I am not sure what is going on here and why it needs to be included in the controller.

First of all it should be lowercased: tokened.rb. But where is your file? It should be here modules/concerns/tokened.rb.
