UUID/ULID

If you're using UUIDs (ULID, GUID, etc) for your User models or Role/Permission models there are a few considerations to note.

NOTE: THIS IS NOT A FULL LESSON ON HOW TO IMPLEMENT UUIDs IN YOUR APP.

Since each UUID implementation approach is different, some of these may or may not benefit you. As always, your implementation may vary.

We use "uuid" in the examples below. Adapt for ULID or GUID as needed.

##Migrations

You will need to update the create_permission_tables.php migration after creating it with php artisan vendor:publish. After making your edits, be sure to run the migration!

User Models using UUIDs If your User models are using uuid instead of unsignedBigInteger then you'll need to reflect the change in the migration provided by this package. Something like the following would be typical, for both model_has_permissions and model_has_roles tables:

// note: this is done in two places in the default migration file, so edit both places:
-   $table->unsignedBigInteger($columnNames['model_morph_key'])
+   $table->uuid($columnNames['model_morph_key'])

Roles and Permissions using UUIDS If you also want the roles and permissions to use a UUID for their id value, then you'll need to change the id fields accordingly, and manually set the primary key.

    Schema::create($tableNames['permissions'], function (Blueprint $table) {
-         $table->bigIncrements('id'); // permission id
+         $table->uuid('uuid')->primary()->unique(); // permission id
//...
    });

    Schema::create($tableNames['roles'], function (Blueprint $table) {
-         $table->bigIncrements('id'); // role id
+         $table->uuid('uuid')->primary()->unique(); // role id
//...
    });

    Schema::create($tableNames['model_has_permissions'], function (Blueprint $table) use ($tableNames, $columnNames) {
-         $table->unsignedBigInteger($pivotPermission);
+         $table->uuid($pivotPermission);
        $table->string('model_type');
//...
        $table->foreign($pivotPermission)
-             ->references('id') // permission id
+             ->references('uuid') // permission id
            ->on($tableNames['permissions'])
            ->onDelete('cascade');
//...

    Schema::create($tableNames['model_has_roles'], function (Blueprint $table) use ($tableNames, $columnNames) {
-         $table->unsignedBigInteger($pivotRole);
+         $table->uuid($pivotRole);
//...
        $table->foreign($pivotRole)
-             ->references('id') // role id
+             ->references('uuid') // role id
            ->on($tableNames['roles'])
            ->onDelete('cascade');//...

    Schema::create($tableNames['role_has_permissions'], function (Blueprint $table) use ($tableNames) {
-         $table->unsignedBigInteger($pivotPermission);
-         $table->unsignedBigInteger($pivotRole);
+         $table->uuid($pivotPermission);
+         $table->uuid($pivotRole);

         $table->foreign($pivotPermission)
-             ->references('id') // permission id
+             ->references('uuid') // permission id
            ->on($tableNames['permissions'])
            ->onDelete('cascade');

         $table->foreign($pivotRole)
-             ->references('id') // role id
+             ->references('uuid') // role id
            ->on($tableNames['roles'])
            ->onDelete('cascade'); 

##Configuration (OPTIONAL)

You might want to change the pivot table field name from model_id to model_uuid, just for semantic purposes. For this, in the permission.php configuration file edit column_names.model_morph_key:

• OPTIONAL: Change to model_uuid instead of the default model_id.

        'column_names' => [    
        /*
         * Change this if you want to name the related pivots other than defaults
         */
        'role_pivot_key' => null, //default 'role_id',
        'permission_pivot_key' => null, //default 'permission_id',

        /*
         * Change this if you want to name the related model primary key other than
         * `model_id`.
         *
         * For example, this would be nice if your primary keys are all UUIDs. In
         * that case, name this `model_uuid`.
         */
-             'model_morph_key' => 'model_id',
+             'model_morph_key' => 'model_uuid',
        ],

• If you extend the models into your app, be sure to list those models in your permissions.php configuration file. See the Extending section of the documentation and the Models section below.

##Models

If you want all the role/permission objects to have a UUID instead of an integer, you will need to Extend the default Role and Permission models into your own namespace in order to set some specific properties. (See the Extending section of the docs, where it explains requirements of Extending, as well as the permissions.php configuration settings you need to update.)

Examples:

Create new models, which extend the Role and Permission models of this package, and add Laravel's HasUuids trait (available since Laravel 9):

php artisan make:model Role
php artisan make:model Permission

App\Model\Role.php

<?php
namespace App\Models;

use Illuminate\Database\Eloquent\Concerns\HasUuids;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Spatie\Permission\Models\Role as SpatieRole;

class Role extends SpatieRole
{
    use HasFactory;
    use HasUuids;
    protected $primaryKey = 'uuid';
}

App\Model\Permission.php

<?php
namespace App\Models;

use Illuminate\Database\Eloquent\Concerns\HasUuids;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Spatie\Permission\Models\Permission as SpatiePermission;

class Permission extends SpatiePermission
{
    use HasFactory;
    use HasUuids;
    protected $primaryKey = 'uuid';
}

And edit config/permission.php

    'models' => [

        /*
         * When using the "HasPermissions" trait from this package, we need to know which
         * Eloquent model should be used to retrieve your permissions. Of course, it
         * is often just the "Permission" model but you may use whatever you like.
         *
         * The model you want to use as a Permission model needs to implement the
         * `Spatie\Permission\Contracts\Permission` contract.
         */

-         'permission' => Spatie\Permission\Models\Permission::class
+         'permission' => App\Models\Permission::class,

        /*
         * When using the "HasRoles" trait from this package, we need to know which
         * Eloquent model should be used to retrieve your roles. Of course, it
         * is often just the "Role" model but you may use whatever you like.
         *
         * The model you want to use as a Role model needs to implement the
         * `Spatie\Permission\Contracts\Role` contract.
         */

-         'role' => Spatie\Permission\Models\Role::class,
+         'role' => App\Models\Role::class,

    ],
