Update Some UI part

home/index.html.erb

<div class="container">
  <div class="row">
    <div class="col-sm-10 col-lg-10 col-md-10">
      <p id="notice"><%= notice %></p>
      <h1>All Links</h1>
      <table class="table table-striped">
        <thead>
          <tr>
            <th>Long url</th>
            <th>Short URL</th>
          </tr>
        </thead>
        <%  @urls = current_user.shortened_urls.each do |data| %>
         <tr>
          <td><%= data.url %></td>
          <td><%= link_to "#{ENV["DEFAULT_URL_PROD"]}/#{data.unique_key}", "#{ENV["DEFAULT_URL_PROD"]}/#{data.unique_key}" %></td>
        </tr>
        <% end %></tbody>
        </table>
      <br>
    <%= link_to 'New Url Short', new_url_short_path %>
    </div>
  </div>
</div>

update home/stats.html.erb

<div class="container">
  <div class="row">
    <div class="col-sm-10 col-lg-10 col-md-10">
      <p id="notice"><%= notice %></p>
      <h1>All Links</h1>
      <table class="table table-striped">
        <thead>
          <tr>
            <th>URL</th>
            <th>Short Link</th>
            <th>Total clicks</th>
            <th>Top countries</th>
          </tr>
        </thead>
        <tbody>
<% @stats_all.each do |data| %>
            <tr>
            <td><%= data.url %></td>
            <td><%= link_to "#{ENV["DEFAULT_URL_PROD"]}/#{data.unique_key}", "#{config.default_host}/#{data.unique_key}" %></td>
            <td><%= data.use_count %></td>
            <td><% get_all_top_country(data) %>
             <%= @data %>
            </td>
            </tr>
          <% end %>
        </tbody>
      </table>
      <br>
      <%= link_to 'New Url Short', new_url_short_path %>
    </div>
  </div>
</div>

<%= form_for(@url_short,:html=>{:id=>"your_form_id",:multipart => true,:remote=>true}) do |form |%>
  <div class="field">
    <%= form.label :link %>
    <%= form.text_area :link %>
  </div>
  <div class="actions">
    <%= form.submit "shorten" %>
  </div>
  <div id="message-response">Here is your short URL</div>
  <div id="message-value"></div>
<% end %>
<script type="text/javascript">
  $('#message-response,#message-value').hide();
</script>

Update config/initilalizers/shortner.rb

Shortener.unique_key_length = 5
Shortener.charset = ('a'..'z').to_a + (0..9).to_a

Then We will Add The controller For Generate The URL

 # frozen_string_literal: true
class UrlShortsController < ApplicationController
  
  # GET /url_shorts/new
  def new
    @url_short = UrlShort.new
  end
  
  # POST /url_shorts or /url_shorts.json
  def create
    @data = if current_user.present?
              Shortener::ShortenedUrl.generate(params[:url_short][:link], owner: current_user,
                                                                          expires_at: 24.hours.since)
            else
              Shortener::ShortenedUrl.generate(params[:url_short][:link], expires_at: 24.hours.since)
            end
    respond_to do |format|
      format.js { render 'url_shorts/status' }
    end
  rescue Exception => e
    @error = true
    @error_data = e
    respond_to do |format|
      format.js { render 'url_shorts/status' }
    end
  end
  
  private
  
  # Only allow a list of trusted parameters through.
  def url_short_params
    params.require(:url_short).permit(:link)
  end
end

Then We will Add The Home Controller To list the URL created by current user

class HomeController < ApplicationController
  before_action :authenticate_user!, except: %i[show stats]
  
  # Get all currebt user shorten urls
  def index
    @urls = current_user.shortened_urls
  end
  
  # Redirect to shorten url
  def show
    token = ::Shortener::ShortenedUrl.extract_token(params[:id])
    url = ::Shortener::ShortenedUrl.fetch_with_token(token: token, additional_params: params)
    # do some logging, store some stats
    redirect_to url[:url], status: :moved_permanently
  end
  
  # To show statics all
  def stats
    @stats_all = Shortener::ShortenedUrl.all
  end
end

module Shortener
  class ShortenedUrlsController < ActionController::Metal
    include ActionController::StrongParameters
    include ActionController::Redirecting
    include ActionController::Instrumentation
    include Rails.application.routes.url_helpers
    include Shortener
    # Update the country and IP address while visit links
    def show
      token = ::Shortener::ShortenedUrl.extract_token(params[:id])
      track = Shortener.ignore_robots.blank? || request.human?
      url   = ::Shortener::ShortenedUrl.fetch_with_token(token: token, additional_params: params, track: track)
      country = ISO3166::Country[request.location.country]
      name = begin
        (country.translations[I18n.locale.to_s] || country.name)
      rescue StandardError
        ''
      end
      Country.create(url_id: url[:shortened_url]&.id, name: country, ip: request.location.ip)
      redirect_to url[:url], status: :moved_permanently
    end
  end
end

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable
  has_shortened_urls
end
