title: What does Model::unguard() do in the database seeder file from Laravel 5?
body: <p>I am trying to find out what is the purpose of <code>Model::unguard();</code> and <code>Model::reguard();</code> in the <code>DatabaseSeeder.php</code> file that ships with Laravel. I have gone through the seeding documentation at laravel's site and googled but in vain.</p>
  
  <p>So what is the purpose of <code>Model::unguard();</code>? Assuming <code>Model::reguard();</code> is just the opposite.</p>
