title: Laravel 4 seeding class Sentry not found
body: <p>I'm following a tutorial from <a href="http://www.codeforest.net/laravel4-simple-website-with-backend-1" rel="nofollow">Code Forest</a> an when using <code>php artisan db:seed</code>, I get this error:</p>
  
  <p>PHP Fatal Error: Class 'Sentry' not found in /var/www/app/database/seeds/SentrySeeder.php on line 13</p>
  
  <p>here is SentrySeeder.php :</p>
  
  <pre><code>&lt;?php
  
  use App\Models\User;
  
  class SentrySeeder extends Seeder {
  
  public function run()
  {
      DB::table('users')-&gt;delete();
      DB::table('groups')-&gt;delete();
      DB::table('users_groups')-&gt;delete();
  
      Sentry::getUserProvider()-&gt;create(array(
          'email'       =&gt; 'admin@admin.com',
          'password'    =&gt; "admin",
          'first_name'  =&gt; 'John',
          'last_name'   =&gt; 'McClane',
          'activated'   =&gt; 1,
      ));
  
      Sentry::getGroupProvider()-&gt;create(array(
          'name'        =&gt; 'Admin',
          'permissions' =&gt; array('admin' =&gt; 1),
      ));
  
      // Assign user permissions
      $adminUser  = Sentry::getUserProvider()-&gt;findByLogin('admin@admin.com');
      $adminGroup = Sentry::getGroupProvider()-&gt;findByName('Admin');
      $adminUser-&gt;addGroup($adminGroup);
      }
  
  }
  </code></pre>
  
  <p>And here is <a href="https://github.com/bstrahija/l4-site-tutorial/blob/master/app/models/User.php" rel="nofollow">User model</a></p>
  
  <p>Sentry has been added to apps under providers
  What Am i missing?</p>
