You may discover that it is best to flush this package's cache before seeding, to avoid cache conflict errors. This can be done directly in a seeder class. Here is a sample seeder, which first clears the cache, creates permissions and then assigns permissions to roles (the order of these steps is intentional):
```php
use Illuminate\Database\Seeder;
use Spatie\Permission\Models\Role;
use Spatie\Permission\Models\Permission;
class RolesAndPermissionsSeeder extends Seeder
{
public function run()
{
// Reset cached roles and permissions
app()[\Spatie\Permission\PermissionRegistrar::class]->forgetCachedPermissions();
// create permissions
Permission::create(['name' => 'edit articles']);
Permission::create(['name' => 'delete articles']);
Permission::create(['name' => 'publish articles']);
Permission::create(['name' => 'unpublish articles']);
// create roles and assign created permissions
// this can be done as separate statements
$role = Role::create(['name' => 'writer']);
$role->givePermissionTo('edit articles');
// or may be done by chaining
$role = Role::create(['name' => 'moderator'])
->givePermissionTo(['publish articles', 'unpublish articles']);
$role = Role::create(['name' => 'super-admin']);
$role->givePermissionTo(Permission::all());
}
}
```
