Enable HasRole Trait And Contract

Include HasRole trait and also implement HasRole contract inside your User model.

<?php use HttpOz\Roles\Traits\HasRole; use HttpOz\Roles\Contracts\HasRole as HasRoleContract; use Illuminate\Foundation\Auth\User as Authenticatable; use Illuminate\Notifications\Notifiable; class User extends Authenticatable implements HasRoleContract { use Notifiable, HasRole; /// }

And that’s it!

Usage

Creating Roles

$adminRole = \HttpOz\Roles\Models\Role::create([ ‘name’ => ‘Admin’, ‘slug’ => ‘admin’, ‘description’ => ‘Custodians of the system.’, // optional ‘group’ => ‘default’ // optional, set as ‘default’ by default ]); $moderatorRole = \HttpOz\Roles\Models\Role::create([ ‘name’ => ‘Forum Moderator’, ‘slug’ => ‘forum.moderator’, ]);

Because of Slugable trait, if you make a mistake and for example leave a space in slug parameter, it’ll be replaced with a dot automatically, because of str_slug function.

Attaching And Detaching Roles

It’s really simple. You fetch a user from database and call attachRole method. There is BelongsToMany relationship between User and Role model.

use App\User; $user = User::find($id); $user->attachRole($adminRole); // you can pass whole object, or just an id
$user->detachRole($adminRole); // in case you want to detach role $user->detachAllRoles(); // in case you want to detach all roles

Syncing Roles

You may also use the sync method to attach roles to a user model. Any roles that are not passed into the method will be detached from the user’s roles. So, after this operation is complete, only the roles passed into the method will be attached to the user:

$user = App\User::find($id); $roles = [1, 4, 6]; // using the role IDs we want to assign to a user $user->syncRoles($roles); // you can pass Eloquent collection, or just an array of ids

Checking For Roles

You can now check if the user has required role.

if ($user->isRole(‘admin’)) { // you can pass an id or slug // do something } // or if($user->hasRole(‘admin’)) { // do something } // or if ($user->isAdmin()) { // }

And of course, there is a way to check for multiple roles:

In this case, a user has to have at least one of the given roles. Multiple options have been illustrated below that achieve the same goal.

if ($user->isRole(‘admin|forum.moderator’)) { // do something } if($user->isRole(‘admin, forum.moderator’)){ // do something } if($user->isRole([‘admin’, ‘forum.moderator’])){ // do something } if($user->isOne(‘admin|forum.moderator’)){ // do something } if($user->isOne(‘admin, forum.moderator’)){ // do something } if($user->isOne([‘admin’, ‘forum.moderator’])){ // do something }

In this case, a user has to have all the given roles. Multiple options have been illustrated below that achieve the same goal.

if ($user->isRole(‘admin|forum.moderator’, true)) { // do something } if($user->isRole(‘admin, forum.moderator’, true)){ // do something } if($user->isRole([‘admin’, ‘forum.

moderator’], true)){ // do something } if($user->isAll(‘admin|forum.moderator’)){ // do something } if($user->isAll(‘admin, forum.moderator’)){ // do something } if($user->isAll([‘admin’, ‘forum.moderator’])){ // do something }

Find users by role

There are multiple ways to get a list of users by their given role.

Using the role’s id

$admins = Role::find(1)->users;

Using the role’s slug

$ adminRole = Role :: findBySlug (‘admin’); $ admins = $ adminRole-> users;

Using the role’s group

$adminRole = Role::where(‘group’, ‘forum.moderator’)->first(); $admins = $adminRole->users;

If you use soft delete on your Users model, and want to include deleted users, you can use usersWithTrashed method instead of users.

Groups

if ($user->group() == ‘application.managers’) { // } if ($user->inGroup(‘application.managers’)) { // if true do something }

If a user has multiple roles, method group returns the first one in alphabetical order (a better implementation of this will be explored).

Group is intended to collectively organise and assign permissions (Laravel’s built in authorization feature) to a role group that can be shared by multiple roles (examples and implementation to be added to documentation in future).

Blade Extensions

There are two Blade extensions. Basically, it is replacement for classic if statements.

@role(‘admin’) // @if(Auth::check() && Auth::user()->isRole(‘admin’)) // user is admin @endrole @group(‘application.managers’) // @if(Auth::check() && Auth::user()->group() == ‘application.managers’) // user belongs to ‘application.managers’ group @endgroup @role(‘admin|moderator’, ‘all’) // @if(Auth::check() && Auth::user()->isRole(‘admin|moderator’, ‘all’)) // user is admin and also moderator @else // something else @endrole

Middleware

This package comes with VerifyRole and VerifyGroup middleware. You must add them inside your app/Http/Kernel.php file.

/** * The application’s route middleware. * * @var array */ protected $routeMiddleware = [ // … ‘role’ => \HttpOz\Roles\Middleware\VerifyRole::class, ‘group’ => \HttpOz\Roles\Middleware\VerifyGroup::class, ];

Now you can easily protect your routes.

$router->get(‘/example’, [ ‘as’ => ‘example’, ‘middleware’ => ‘role:admin’, ‘uses’ => ‘ExampleController@index’, ]); $router->get(‘/example’, [ ‘as’ => ‘example’, ‘middleware’ => ‘group:application.managers’, ‘uses’ => ‘ExampleController@index’, ]);

It throws \HttpOz\Roles\Exceptions\RoleDeniedException or \HttpOz\Roles\Exceptions\GroupDeniedException exceptions if it goes wrong.

You can catch these exceptions inside app/Exceptions/Handler.php file and do whatever you want. You can control the error page that your application users see when they try to open a page their role is not allowed to. This package already has a view bundled with it that should have been published to resources/views/vendor/roles/error.blade.php when you published the package. Simply add the below condition inside your app\Exceptions\Handler.php’s render function. Feel free to point to another view of your choice.

/** * Render an exception into an HTTP response. * * @param \Illuminate\Http\Request $request * @param \Exception $exception * @return \Illuminate\Http\Response */ public function render($request, Exception $exception) { if ($exception instanceof \HttpOz\Roles\Exceptions\RoleDeniedException || $exception instanceof \HttpOz\Roles\Exceptions\GroupDeniedException) { return response()->view(‘vendor.roles.error’, compact(‘exception’), 403); } return parent::render($request, $exception); }

Config File

You can change connection for models, slug separator, models path and there is also a handy pretend feature. Have a look at config file for more information.

Caching

The configuration for cache expiry is defaulted to 2 weeks (in seconds). You can update this value to suit your project specific needs.
