Installation

To get started, install Authorization via the Composer package manager:

composer require directorytree/authorization

The Authorization service provider registers its own database migration directory with the framework, so you should migrate your database after installing the package. The Authorization migrations will create the tables your application needs to store roles and permissions:

php artisan migrate

Now insert the DirectoryTree\Authorization\Traits\Authorizable onto your App\Models\User model:

<?php

namespace App\Models;

use DirectoryTree\Authorization\Traits\Authorizable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Authorizable;

    // ...
}

You can now perform user authorization.

Migration Customization

If you would not like to use Authorization's default migrations, you should call the Authorization::ignoreMigrations method in the register method of your AppServiceProvider. You may export the default migrations using php artisan vendor:publish --tag=authorization-migrations.

use DirectoryTree\Authorization\Authorization;

/**
 * Register any application services.
 *
 * @return void
 */
public function register()
{
    Authorization::ignoreMigrations();
}

Model Customization

By default, the App\Models\User class is registered as the authorizable user model.

You're free to extend the models used internally by Authorization, or create your own.

Instruct Authorization to use your own models via the Authorization class in your AuthServiceProvider:

use DirectoryTree\Authorization\Authorization;

/**
 * Register any authentication / authorization services.
 *
 * @return void
 */
public function boot()
{
    $this->registerPolicies();

    Authorization::useUserModel(\App\Models\User::class);
    Authorization::useRoleModel(\App\Models\Role::class);
    Authorization::usePermissionModel(\App\Models\Permission::class);
}

Be sure to add the relevant traits for each of your custom models:

Role Model:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use DirectoryTree\Authorization\Traits\ManagesPermissions;

class Role extends Model
{
    use ManagesPermissions;
}

Permission Model:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use DirectoryTree\Authorization\Traits\HasUsers;
use DirectoryTree\Authorization\Traits\HasRoles;
use DirectoryTree\Authorization\Traits\ClearsCachedPermissions;

class Permission extends Model
{
    use HasUsers, HasRoles, ClearsCachedPermissions;
}

Usage

Authorization uses native Laravel relationships, so there's no need to learn a new API if you don't want to.

Due to Authorization's trait based implementation, all of Authorization's functionality can be overridden or extended with you own implementation.

Managing Roles & Permissions

Create a permission:

use DirectoryTree\Authorization\Permission;

$createUsers = Permission::create([
    'name' => 'users.create',
    'label' => 'Create Users',
]);

Create a role:

use DirectoryTree\Authorization\Role;

$admin = Role::create([
    'name' => 'administrator',
    'label' => 'Admin',
]);

Grant the permission to a role:

$admin->permissions()->save($createUsers);

Now assign the role to the user:

$user->roles()->save($admin);

You may also use the grant() or revoke() method on a Role model:

// Using the permission's name:
$admin->grant('users.create');

// Using a permission model:
$admin->grant($permission);

// Granting multiple permissions:
$admin->grant(['users.create', 'users.edit']);

// Granting a collection of models:
$admin->grant(Permission::all());

// Using a mix of models and permission name:
$admin->grant([$createUsers, 'users.edit']);

You may also sync a role's permissions using the grantOnly() method:

// All permissions will be removed except, except for the given:
$admin->grantOnly('users.create');

// Using the permission's name:
$admin->revoke('users.create');

// Using a permission model:
$admin->revoke($permission);

// Revoking multiple permissions:
$admin->revoke(['users.create', 'users.edit']);

// Revoking a collection of models:
$admin->revoke(Permission::all());

// Using a mix of models and permission name:
$admin->revoke([$createUsers, 'users.edit']);

You may also detach all permissions from a role using revokeAll():

$admin->revokeAll();

Managing Users & Permissions

You can also create user specific permissions:

$createUsers = Permission::create([
    'name' => 'users.create',
    'label' => 'Create Users',
]);

$user->permissions()->save($createUsers);

As with roles, may also use the grant() or revoke() method on an authorizable User model:

// Using the permission's name:
$user->grant('users.create');

// Using a permission model:
$user->grant($permission);

// Granting multiple permissions:
$user->grant(['users.create', 'users.edit']);

// Granting a collection of models:
$user->grant(Permission::all());

// Using a mix of models and permission name:
$user->grant([$createUsers, 'users.edit']);

You may also sync a users' permissions using the grantOnly() method:

// All permissions will be removed except, except for the given:
$user->grantOnly('users.create');

// Using the permission's name:
$user->revoke('users.create');

// Using a permission model:
$user->revoke($permission);

// Granting multiple permissions:
$user->revoke(['users.create', 'users.edit']);

// Granting a collection of models:
$user->revoke(Permission::all());

// Using a mix of models and permission name:
$user->revoke([$createUsers, 'users.edit']);

Checking Permissions & Roles

Using Laravel's native can() method:

if (Auth::user()->can('users.create')) {
    // This user can create other users.
}

Using Laravel's native authorize() method in your controllers:

public function create()
{
    $this->authorize('users.create');

    User::create(['...']);
}

Using Laravel's native Gate facade:

if (Gate::allows('users.create')) {
    //
}

Using Laravel's native @can directive in your views:

@can('users.create')
    <!-- This user can create other users. -->
@endcan

Checking Permissions & Roles (Using Authorization Package Methods)

Checking for permission:

// Using the permissions name.
if ($user->hasPermission('users.create')) {
    //
}

// Using the permissions model.
if ($user->hasPermission($createUsers)) {
    //
}

Checking for multiple permissions:

if ($user->hasPermissions(['users.create', 'users.edit'])) {
    // This user has both creation and edit rights.
} else {
    // The user doesn't have one of the specified permissions.
}

Checking if the user has any permissions:

if ($user->hasAnyPermissions(['users.create', 'users.edit', 'users.destroy'])) {
    // This user either has create, edit or destroy permissions.
} else {
    // The user doesn't have any of the specified permissions.
}

Checking if the user has a role:

if ($user->hasRole('administrator')) {
    // This user is an administrator.
} else {
    // The user isn't an administrator.
}

Checking if the user has specified roles:

if ($user->hasRoles(['administrator', 'member'])) {
    // This user is an administrator and a member.
} else {
    // The user isn't an administrator or member.
}

Checking if the user has any specified roles:

if ($user->hasAnyRoles(['administrator', 'member', 'guest'])) {
    // This user is either an administrator, member or guest.
} else {
    // The user doesn't have any of these roles.
}

Caching

By default all permissions are cached to prevent them from being retrieved on every request.

This cache is automatically flushed when permissions are created, updated, or deleted.

If you would like to disable the cache, call Authorization::disablePermissionCache in your AuthServiceProvider:

use DirectoryTree\Authorization\Authorization;

/**
 * Register any authentication / authorization services.
 *
 * @return void
 */
public function boot()
{
    $this->registerPolicies();

    Authorization::disablePermissionCache();
}

Cache Key

By default, the permission cache key is authorization.permissions.

To alter the cache key, call Authorization::cacheKey in your AuthServiceProvider:

use DirectoryTree\Authorization\Authorization;

/**
 * Register any authentication / authorization services.
 *
 * @return void
 */
public function boot()
{
    $this->registerPolicies();

    Authorization::cacheKey('my-key');
}

Cache Expiry

By default, the permission cache will expire daily.

To alter this expiry date, call Authorization::cacheExpiresIn in your AuthServiceProvider:

use DirectoryTree\Authorization\Authorization;

/**
 * Register any authentication / authorization services.
 *
 * @return void
 */
public function boot()
{
    $this->registerPolicies();

    Authorization::cacheExpiresIn(now()->addWeek());
}

Gate Registration

By default all permissions you create are registered in Laravel's Gate.

If you would like to disable this, call Authorization::disableGateRegistration in your AuthServiceProvider:

use DirectoryTree\Authorization\Authorization;

/**
 * Register any authentication / authorization services.
 *
 * @return void
 */
public function boot()
{
    $this->registerPolicies();

    Authorization::disableGateRegistration();
}

Middleware

Authorization includes two useful middleware classes you can utilize for your routes.

Insert them into your app/Http/Kernel.php:

/**
 * The application's route middleware.
 *
 * These middleware may be assigned to groups or used individually.
 *
 * @var array
 */
protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,

    // The role middleware:
    'role' => \DirectoryTree\Authorization\Middleware\RoleMiddleware::class,

    // The permission middleware:
    'permission' => \DirectoryTree\Authorization\Middleware\PermissionMiddleware::class,
];

Once you've added them, you can start using them.

Note: When a user does not meet the requirements using the middleware, a 403 HTTP exception is thrown.

To guard a route to only allow specific permissions:

Route::get('users', [
    'uses' => 'UsersController@index',
    'middleware' => 'permission:users.index',
]);

// Multiple permissions:
Route::get('users', [
    'uses' => 'UsersController@index',
    // Users must have index **and** create rights to access this route.
    'middleware' => 'permission:users.index,users.create',
]);

To guard a route to allow a specific role:

Route::get('users', [
    'uses' => 'UsersController@index',
    'middleware' => 'role:administrator',
]);

// Multiple roles:
Route::get('users', [
    'uses' => 'UsersController@index',
    // Users must be an administrator **and** a member to access this route.
    'middleware' => 'role:administrator,member',
]);

Running Tests

To run your applications tests, you must instantiate the PermissionRegistrar inside your TestCase::setUp() method before running your tests for permissions to register properly:

use DirectoryTree\Authorization\PermissionRegistrar;

protected function setUp() : void
{
    parent::setUp();

    app(PermissionRegistrar::class)->register();
}
