Role and Permission data are cached to speed up performance.

When you use the built-in functions for manipulating roles and permissions, the cache is automatically reset for you, and relations are automatically reloaded for the current model record:

// When handling permissions assigned to roles:
$role->givePermissionTo('edit articles');
$role->revokePermissionTo('edit articles');
$role->syncPermissions(params);

// When linking roles to permissions:
$permission->assignRole('writer');
$permission->removeRole('writer');
$permission->syncRoles(params);

HOWEVER, if you manipulate permission/role data directly in the database instead of calling the supplied methods, then you will not see the changes reflected in the application unless you manually reset the cache.

Additionally, because the Role and Permission models are Eloquent models which implement the RefreshesPermissionCache trait, creating and deleting Roles and Permissions will automatically clear the cache. If you have created your own models which do not extend the default models then you will need to implement the trait yourself.

NOTE: User-specific role/permission assignments are kept in-memory since v4.4.0, so the cache-reset is no longer called since v5.1.0 when updating User-related assignments. Examples:

// These operations on a User do not call a cache-reset, because the User-related assignments are in-memory.
$user->assignRole('writer');
$user->removeRole('writer');
$user->syncRoles(params);

To manually reset the cache for this package, you can run the following in your app code:

app()->make(\Spatie\Permission\PermissionRegistrar::class)->forgetCachedPermissions();

Or you can use an Artisan command:

php artisan permission:cache-reset

(This command is effectively an alias for artisan cache:forget spatie.permission.cache but respects the package config as well.)

This package allows you to customize cache-related operations via its config file. In most cases the defaults are fine; however, in a multitenancy situation you may wish to do some cache-prefix overrides when switching tenants. See below for more details.

The default cache expiration_time is 24 hours. If you wish to alter the expiration time you may do so in the config/permission.php file, in the cache array.

The default cache key is spatie.permission.cache. We recommend not changing the cache "key" name. Usually changing it is a bad idea. More likely setting the cache prefix is better, as mentioned below.

Laravel Tip: If you are leveraging a caching service such as redis or memcached and there are other sites running on your server, you could run into cache clashes between apps.

To prevent other applications from accidentally using/changing your cached data, it is prudent to set your own cache prefix in Laravel's /config/cache.php to something unique for each application which shares the same caching service.

Most multi-tenant "packages" take care of this for you when switching tenants.

You can configure the package to use any of the Cache Stores you've configured in Laravel's config/cache.php. This way you can point this package's caching to its own specified resource.

In config/permission.php set cache.store to the name of any one of the config/cache.php stores you've defined.

Setting 'cache.store' => 'array' in config/permission.php will effectively disable caching by this package between requests (it will only cache in-memory until the current request is completed processing, never persisting it).

Alternatively, in development mode you can bypass ALL of Laravel's caching between visits by setting CACHE_DRIVER=array in .env. You can see an example of this in the default phpunit.xml file that comes with a new Laravel install. Of course, don't do this in production though!

This situation is not specific to this package, but is mentioned here due to the common question being asked.

If you are using the File cache Store and run into problems clearing the cache, it is most likely because your filesystem's permissions are preventing the PHP CLI from altering the cache files because the PHP-FPM process is running as a different user.

Work with your server administrator to fix filesystem ownership on your cache files.

TIP: If you have CACHE_STORE=database set in your .env, remember that you must install Laravel's cache tables via a migration before performing any cache operations. If you fail to install those migrations, you'll run into errors like Call to a member function perform() on null when the cache store attempts to purge or update the cache. This package does strategic cache resets in various places, so may trigger that error if your app's cache dependencies aren't set up.
