easy_admin_bundle:

    prefix: /admin
    type: annotation

symfony console router:match /admin

                                                                                                                       
 [ERROR] None of the routes match the path "/admin"

What am I missing?

Answer 1

As others have already said you need to create a dashboard with:

php bin/console make:admin:dashboard

And then create at least one crud controller. Since it seems you're using the Fast Track book, you need to type the following command twice and make one for both Comment and Conference:

php bin/console make:admin:crud

I am using the Fast Track book too and this is how my files ended up. I am still learning easy admin3 and thus make no claims as to best practice, but this should make the menus look as they do in the Fast Track screenshots:

src/Controller/Admin/DashboardController.php:

/**
 * @Route("/admin", name="admin")
 */
public function index(): Response
{
    $routeBuilder = $this->get(CrudUrlGenerator::class)->build();

    return $this->redirect($routeBuilder->setController(ConferenceCrudController::class)->generateUrl());
}

public function configureDashboard(): Dashboard
{
    return Dashboard::new()
        ->setTitle('Guestbook');
}

public function configureMenuItems(): iterable
{
    yield MenuItem::linktoRoute('Back to website', 'fa fa-home', 'homepage');
    yield MenuItem::linkToCrud('Conference', 'fa fa-map-marker', Conference::class);
    yield MenuItem::linkToCrud('Comment', 'fa fa-comment', Comment::class);
}

src/Controller/Admin/CommentCrudController.php:

public static function getEntityFqcn(): string
{
    return Comment::class;
}

public function configureFields(string $pageName): iterable
{
    return [
        IdField::new('id')->hideOnForm(),
        TextField::new('author'),
        TextareaField::new('text')->hideOnIndex(), // Removing ->hideOnIndex() will display a link to a text modal
        EmailField::new('email'),
        DateTimeField::new('createdAt')->hideOnForm(),
        ImageField::new('photoFilename', 'Photo')->setBasePath('/uploads/photos')->hideOnForm(),

        AssociationField::new('conference')
    ];
}

src/Controller/Admin/ConferenceCrudController.php

public static function getEntityFqcn(): string
{
    return Conference::class;
}

public function configureFields(string $pageName): iterable
{
    return [
        IdField::new('id')->hideOnForm(),
        TextField::new('city'),
        TextField::new('year'),
        BooleanField::new('isInternational'),
        IntegerField::new('commentCount', 'Comments')->hideOnForm()
    ];
}

And in src/Entity/Conference.php I added the following to make commentCount available:

public function getCommentCount(): int
{
    return $this->comments->count();
}

To generate the createdAt datetime automatically when the comment is submitted, I first installed the following bundle:

$ composer require stof/doctrine-extensions-bundle

And then modified config/packages/stof_doctrine_extensions.yaml:

stof_doctrine_extensions:
    default_locale: en_US
    orm:
        default:
            tree: true
            timestampable: true

And finally decorated private $createdAt in src/Entity/Comment.php with the following:

/**
 * @var \DateTime
 * @ORM\Column(type="datetime")
 * @Gedmo\Mapping\Annotation\Timestampable(on="create")
 * @Doctrine\ORM\Mapping\Column(type="datetime")
 */
private $createdAt;

You need to create at least one dashboard. Try:

php bin/console make:admin:dashboard

Next, you can create a CrudController with:

php bin/console make:admin:crud

Yeah, I am reading this book right now and ran into the same issue.

First, make sure that your working directory is clean (run "git status" and remove all changes made by EasyAdminBundle setup).

Then run:

composer require easycorp/easyadmin-bundle:2.*

to install EasyAdminBundle version 2; with this version, you can proceed as described in the book.
