Create a Dashboard

Install 
$ php bin/console make:admin:dashboard
Enter fullscreen mode Exit fullscreen mode

I was asked a couple of times and used the default:

 Which class name do you prefer for your Dashboard controller? [DashboardController]:
 > 

 In which directory of your project do you want to generate "DashboardController"? [src/Controller/Admin/]:
 > 



 [OK] Your dashboard class has been successfully generated.                                                             


 Next steps:
 * Configure your Dashboard at "src/Controller/Admin/DashboardController.php"
 * Run "make:admin:crud" to generate CRUD controllers and link them from the Dashboard.
Enter fullscreen mode Exit fullscreen mode

Here, you can see the default dashboard!!

easyadmin default dashboard

Well, there is no menu! Let's create your own dashboard and add menus to it.

Create the first dashboard of your own

Let's create a custom template:

$ mkdir templates/admin

$ nvim templates/admin/index.html.twig
Enter fullscreen mode Exit fullscreen mode

Write just this in it:

+ {% extends '@EasyAdmin/page/content.html.twig' %}
Enter fullscreen mode Exit fullscreen mode

Then, edit the controller (src/Controller/Admin/DashboardController.php):

  class DashboardController extends AbstractDashboardController
  {
      #[Route('/admin', name: 'admin')]
      public function index(): Response
      {
-         return parent::index();
+         return $this->render('admin/index.html.twig');
Enter fullscreen mode Exit fullscreen mode

Then prepare assets:

$ yarn encore dev
$ # alternatively, `npm run dev` is available
Enter fullscreen mode Exit fullscreen mode

Besides, you sometimes have to clear cache.

$ php(8) bin/console cache:clear
Enter fullscreen mode Exit fullscreen mode

Reload the dashboard page, and you will see it's replaced with your own.

your own dashboard

There are few menus. Next, let's implement to manage table records.

Prepare an entity

Let's make some entity. It's dealt with by Symfony and Doctrine.

Use make bundle. You will be asked on its schema:

$ php bin/console make:entity
Enter fullscreen mode Exit fullscreen mode

Then make it substantial:

$ php bin/console make:migration
$ # reply yes
$ php bin/console doctrine:migrations:migrate
$ # reply yes
Enter fullscreen mode Exit fullscreen mode

Create a CRUD controller

It's EasyAdmin's turn.

$ php bin/console make:admin:crud
Enter fullscreen mode Exit fullscreen mode

The output was:

 Which Doctrine entity are you going to manage with this CRUD controller?:
  [0] App\Entity\(...)
 > 0

 Which directory do you want to generate the CRUD controller in? [src/Controller/Admin/]:
 > 

 Namespace of the generated CRUD controller [App\Controller\Admin]:
 > 


 [OK] Your CRUD controller class has been successfully generated.                                                       


 Next steps:
 * Configure your controller at "src/Controller/Admin/(...)CrudController.php"
 * Read EasyAdmin docs: https://symfony.com/doc/master/bundles/EasyAdminBundle/index.html
Enter fullscreen mode Exit fullscreen mode

Add a menu on the entity:

  (...)
+ use App\Entity\SamplePack;

  class DashboardController extends AbstractDashboardController
  (...)
      public function configureMenuItems(): iterable
      {
          yield MenuItem::linkToDashboard('Dashboard', 'fa fa-home');
-         // yield MenuItem::linkToCrud('The Label', 'fas fa-list', EntityClass::class);
+         yield MenuItem::linkToCrud('The Label', 'fas fa-list', SamplePack::class);
    }
Enter fullscreen mode Exit fullscreen mode

Then, reload the page.

menu to entity

Yay, got it. Let's click "The Label" on the left side:

entity page

We can manage storage here!!

Conclusion

I tried a new feature released just at the beginning of the year, menu badges.

To show a count:

-         yield MenuItem::linkToCrud('The Label', 'fas fa-list', SamplePackClass::class);
+         yield MenuItem::linkToCrud('The Label', 'fas fa-list', SamplePackClass::class)
+         ->setBadge(468, 'success');
Enter fullscreen mode Exit fullscreen mode

badge of number

Nice.

To show a message:

-         yield MenuItem::linkToCrud('The Label', 'fas fa-list', SamplePackClass::class);
+         yield MenuItem::linkToCrud('The Label', 'fas fa-list', SamplePackClass::class)
+         ->setBadge('Ciao!', 'background: transparent; color: #44bb88; outline: 2px solid white');
Enter fullscreen mode Exit fullscreen mode

badge of string

Sweet 💃💃

If you are a macOS user, ServBay.dev is worth to try. You don't need to spend some time or couple of days to setup anything. Just download it and you can use it immediately. You can run multiple PHP versions simultaneously and switch between them effortlessly.
Honestly, this tool has greatly simplified my PHP development and is definitely worth trying!
