Extends a custom plugin by adding a profile that does not display a tab on newly added fields in OctoberCMS

I followed all the steps on Extending User Plugin , but for some reason I can't see the Profile tab and the newly added fields. Since I used the second approach, lightweight, this is what I did:

• Create plugin and models, etc. under the namespace Alomicuba

• Create and make the necessary changes to the files, as described in the video:

  Plugin.php
  
  <?php namespace Alomicuba\Profile;
  
  use System\Classes\PluginBase;
  use RainLab\User\Models\User as UserModel;
  use RainLab\User\Controllers\Users as UsersController;
  
  /**
   * Profile Plugin Information File
   */
  class Plugin extends PluginBase
  {
      public $requires = ['RainLab.User'];
  
      /**
       * Returns information about this plugin.
       *
       * @return array
       */
      public function pluginDetails()
      {
          return [
              'name'        => 'Profile',
              'description' => 'Add extra functionalities for Alomicuba WS by extends RainLab User',
              'author'      => 'DTS',
              'icon'        => 'icon-users'
          ];
      }
  
      public function boot()
      {
          UserModel::extend(function($model){
              $model->hasOne['profile'] = ['Alomicuba\Profile\Models\Profile'];
          });
  
          UsersController::extendFormFields(function ($form, $model, $context){
              if ($model instanceof UserModel)
                  return;
  
              $form->addTabFields([
                  'pinCode' => [
                      'label' => 'PIN',
                      'tab' => 'Profile'
                  ],
                  'phone2' => [
                      'label' => 'Teléfono (2)',
                      'tab' => 'Profile'
                  ],
                  'phone3' => [
                      'label' => 'Teléfono (3)',
                      'tab' => 'Profile'
                  ],
                  'phone4' => [
                      'label' => 'Teléfono (4)',
                      'tab' => 'Profile'
                  ]
              ]);
          });
      }
  }
  
  add_profiles_fields_to_user_table.php
  
  <?php namespace Alomicuba\Profile\Updates;
  
  use Schema;
  use October\Rain\Database\Updates\Migration;
  
  class AddProfilesFieldsToUserTable extends Migration
  {
  
      public function up()
      {
          Schema::table('users', function($table)
          {
              $table->integer('pinCode')->unsigned();
              $table->dateTime('pinCodeDateTime');
              $table->integer('phone2')->unsigned()->nullable();
              $table->integer('phone3')->unsigned()->nullable();
              $table->integer('phone4')->unsigned()->nullable();
          });
      }
  
      public function down()
      {
          $table->dropDown([
              'pinCode',
              'pinCodeDateTime',
              'phone2',
              'phone3',
              'phone4'
          ]);
      }
  }
  
  version.yaml
  1.0.1: First version of Profile
  1.0.2:
      - Created profiles table
      - create_profiles_table.php
      - add_profiles_fields_to_user_table.php
  
  Profile.php (Model)
  <?php namespace Alomicuba\Profile\Models;
  
  use Model;
  
  /**
   * Profile Model
   */
  class Profile extends Model
  {
      /**
       * @var string The database table used by the model.
       */
      public $table = 'alomicuba_profile_profiles';
  
      /**
       * @var array Relations
       */
      public $belongsTo = [
          'user' => ['RainLab\User\Models\User']
      ];
  
  
      // This method is not need anymore since I'll use the second approach
      public static function getFromUser($user)
      {
          if ($user->profile)
              return $user->profile;
  
          $profile = new static;
          $profile->user = $user;
          $profile->save();
  
          $user->profile = $profile;
  
          return $profile;
      }
  }
  
        
  
          
          
          
        
  
      

But when I edit an existing user, I didn't see the Profile tab, nor did I see any new added field. See image below:

Are there any tips on this? Did I miss something?

Also I have a few questions about plugin extension:

• How do I add a required field to the registration form?
• How to display each new added field in the account form?
