Dashboard Setup

namespace App\Controller\Admin;

use EasyCorp\Bundle\EasyAdminBundle\Config\{Dashboard, MenuItem};
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractDashboardController;

class DashboardController extends AbstractDashboardController
{
    #[Route('/admin', name: 'admin')]
    public function index(): Response
    {
        return $this->render('admin/dashboard.html.twig');
    }

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

    public function configureMenuItems(): iterable
    {
        yield MenuItem::linkToDashboard('Dashboard', 'fa fa-home');
        yield MenuItem::linkToCrud('Posts', 'fa fa-newspaper', Post::class);
        yield MenuItem::linkToCrud('Categories', 'fa fa-tags', Category::class);
    }
}

CRUD Controllers

namespace App\Controller\Admin;

use App\Entity\Product;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;
use EasyCorp\Bundle\EasyAdminBundle\Field\*;

class ProductCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Product::class;
    }

    public function configureCrud(Crud $crud): Crud
    {
        return $crud
            ->setEntityLabelInSingular('Product')
            ->setSearchFields(['name', 'sku'])
            ->setDefaultSort(['createdAt' => 'DESC']);
    }

    public function configureFields(string $pageName): iterable
    {
        yield TextField::new('name');
        yield MoneyField::new('price')->setCurrency('USD');
        yield AssociationField::new('category')->autocomplete();
        yield ImageField::new('photo')
            ->setBasePath('uploads')
            ->setUploadDir('public/uploads');
        yield BooleanField::new('isActive')->renderAsSwitch();
    }
}

Add filters:

public function configureFilters(Filters $filters): Filters
{
    return $filters
        ->add('name')
        ->add(BooleanFilter::new('isActive'));
}

See Fields, Actions, CRUD, Filters for complete examples

Common Patterns

Custom Query Filtering

public function createIndexQueryBuilder(/* ... */): QueryBuilder
{
    $qb = parent::createIndexQueryBuilder(...func_get_args());
    $qb->andWhere('entity.isActive = :active')
       ->setParameter('active', true);
    return $qb;
}

Audit Trail

public function updateEntity(EntityManagerInterface $em, $entity): void
{
    $entity->setUpdatedBy($this->getUser());
    parent::updateEntity($em, $entity);
}

Security

return $crud->setEntityPermission('ROLE_ADMIN');
return $actions->setPermission(Action::DELETE, 'ROLE_SUPER_ADMIN');

Configuration

# config/routes.yaml
admin:
    resource: App\Controller\Admin\DashboardController
    type: easyadmin
    prefix: /admin

# config/packages/security.yaml
security:
    access_control:
        - { path: ^/admin, roles: ROLE_ADMIN }

Troubleshooting

• Routes not found: php bin/console cache:clear
• Images not displaying: Check public/uploads/ exists
• Collections not saving: Add ->setFormTypeOptions(['by_reference' => false])
• Autocomplete not working: composer require symfony/ux-autocomplete
