2. Update Database Schema: Apply the entity changes to your database: docker-compose exec php php bin/console make:migration
docker-compose exec php php bin/console doctrine:migrations:migrate

3. Add API Platform Annotations: Open your `src/Entity/Book.php` file. To expose the `Book` entity as an API resource, add the `#[ApiResource]` attribute above the class definition: // src/Entity/Book.php
namespace App\Entity;
use ApiPlatform\Metadata\ApiResource;
use Doctrine\ORM\Mapping as ORM;
#[ORM\Entity]
#[ApiResource] // This is the magic!
class Book
{
   // ... existing properties and methods
}


That's it! Your Book entity is now a fully functional API resource.

Testing Your API Endpoints and Interacting with the Documentation.
