# Upgrade from 4.0 to 5.0

In order to upgrade from Laratrust 4.0 to 5.0 you have to follow these steps:

1. Change your composer.json to require the 5.0 version of Laratrust:

"santigarcor/laratrust": "5.0.*"

2. Run composer update to update the source code.

3. Run php artisan config:clear and php artisan cache:clear.

4. Update your config/laratrust.php:

   4.1. Backup your config/laratrust.php configuration values.

   4.2. Delete the config/laratrust.php file.

   4.3. Run php artisan vendor:publish --tag=laratrust.

   4.4. Update the config/laratrust.php file with your old values.

   4.5. Set the middleware.register value to false.

   4.6. Set the teams_strict_check value to true only if you are using teams.

5. Inside your Role, Permission and Team models update the use statement from:

   • use Laratrust\LaratrustRole to use Laratrust\Models\LaratrustRole;
   • use Laratrust\LaratrustPermission to use Laratrust\Models\LaratrustPermission;
   • use Laratrust\LaratrustTeam to use Laratrust\Models\LaratrustTeam;

6. If you use the ability method and you pass it comma separated roles or permissions, change them to a pipe separated string:

 // From
$user->ability('admin,owner', 'create-post,edit-user');
// To
$user->ability('admin|owner', 'create-post|edit-user');

7. If you are using the Ownable interface, please update all the classes implementing it:

// From
public function ownerKey() {}
// To
public function ownerKey($owner) {}

8. If you use teams and in your code you use the syncRoles and syncPermissions read the new sync method behavior.

9. The cachedRoles and cachedPermissions methods now return an array when you have the laratrust.use_cache option set to true. So if you use these methods, please check your code.

10. Delete the LaratrustSeeder.php file and run php artisan laratrust:seeder.

11. Run composer dump-autoload.

Now you can use the 5.0 version without any problem.
