php artisan make:provider PermissionsServiceProvider

Daftarkan service provider Anda dan lanjutkan ke metode boot untuk memberi kami Gateway untuk menggunakan metode can().

namespace App\Providers;

use App\Permission;
use Illuminate\Support\Facades\Blade;
use Illuminate\Support\Facades\Gate;
use Illuminate\Support\ServiceProvider;

class PermissionsServiceProvider extends ServiceProvider
{
   
    public function register()
    {
        //
    }

    public function boot()
    {
        try {
            Permission::get()->map(function ($permission) {
                Gate::define($permission->slug, function ($user) use ($permission) {
                    return $user->hasPermissionTo($permission);
                });
            });
        } catch (\Exception $e) {
            report($e);
            return false;
        }

        //Blade directives
        Blade::directive('role', function ($role) {
             return "if(auth()->check() && auth()->user()->hasRole({$role})) :"; //return this if statement inside php tag
        });

        Blade::directive('endrole', function ($role) {
             return "endif;"; //return this endif statement inside php tag
        });

    }
}

sekarang kita harus mendaftarkan PermissionsServiceProvider kita. Buka file berikut ini, tambahkan ini di array providers.
config\app.php

 'providers' => [

        App\Providers\PermissionsServiceProvider::class,
    
 ],

Anda dapat mempelajari lebih lanjut tentang  Gate facade Laravel di dokumentasi Laravel . Anda dapat mengujinya sebagai:

dd($user->can('permission-slug'));

Langkah 9: Tambahkan Data Dummy Untuk Diperiksa

Route::get('/roles', 'PermissionController@Permission');

namespace App\Http\Controllers;

use App\Permission;
use App\Role;
use App\User;
use Illuminate\Http\Request;

class PermissionController extends Controller
{   

    public function Permission()
    {   
    	$dev_permission = Permission::where('slug','create-tasks')->first();
		$manager_permission = Permission::where('slug', 'edit-users')->first();

		//RoleTableSeeder.php
		$dev_role = new Role();
		$dev_role->slug = 'developer';
		$dev_role->name = 'Front-end Developer';
		$dev_role->save();
		$dev_role->permissions()->attach($dev_permission);

		$manager_role = new Role();
		$manager_role->slug = 'manager';
		$manager_role->name = 'Assistant Manager';
		$manager_role->save();
		$manager_role->permissions()->attach($manager_permission);

		$dev_role = Role::where('slug','developer')->first();
		$manager_role = Role::where('slug', 'manager')->first();

		$createTasks = new Permission();
		$createTasks->slug = 'create-tasks';
		$createTasks->name = 'Create Tasks';
		$createTasks->save();
		$createTasks->roles()->attach($dev_role);

		$editUsers = new Permission();
		$editUsers->slug = 'edit-users';
		$editUsers->name = 'Edit Users';
		$editUsers->save();
		$editUsers->roles()->attach($manager_role);

		$dev_role = Role::where('slug','developer')->first();
		$manager_role = Role::where('slug', 'manager')->first();
		$dev_perm = Permission::where('slug','create-tasks')->first();
		$manager_perm = Permission::where('slug','edit-users')->first();

		$developer = new User();
		$developer->name = 'Mahedi Hasan';
		$developer->email = '[email protected]';
		$developer->password = bcrypt('secrettt');
		$developer->save();
		$developer->roles()->attach($dev_role);
		$developer->permissions()->attach($dev_perm);

		$manager = new User();
		$manager->name = 'Hafizul Islam';
		$manager->email = '[email protected]';
		$manager->password = bcrypt('secrettt');
		$manager->save();
		$manager->roles()->attach($manager_role);
		$manager->permissions()->attach($manager_perm);

		
		return redirect()->back();
    }
}

$user = $request->user();
dd($user->hasRole('developer')); //will return true, if user has role
dd($user->givePermissionsTo('create-tasks'));// will return permission, if not null
dd($user->can('create-tasks')); // will return true, if user has permission

@role('developer')

 Hello developer

@endrole

Langkah 10: Siapkan Middleware

php artisan make:middleware RoleMiddleware

namespace App\Http\Middleware;

use Closure;

class RoleMiddleware
{

    public function handle($request, Closure $next, $role, $permission = null)
    {
        if(!$request->user()->hasRole($role)) {

             abort(404);

        }

        if($permission !== null && !$request->user()->can($permission)) {

              abort(404);
        }

        return $next($request);

    }
}

protected $routeMiddleware = [
    .
    .
    'role' => \App\Http\Middleware\RoleMiddleware::class,
];

Route::group(['middleware' => 'role:developer'], function() {

   Route::get('/admin', function() {

      return 'Welcome Admin';
      
   });

});

public function __construct()
{
   $this->middleware('auth'); 
}


public function store(Request $request)
{
    if ($request->user()->can('create-tasks')) {
        //Code goes here
    }
}

public function destroy(Request $request, $id)
{   
    if ($request->user()->can('delete-tasks')) {
      //Code goes here
    }

}
