 API Platform will find the operation matching this `itemUriTemplate` and use it to generate the IRI.
 
 If this option is not set, the first `Get` operation is used to generate the IRI.

-## Expose a Model Without Any Routes
-
-Sometimes, you may want to expose a model, but want it to be used through subrequests only, and never through item or collection operations.
-Because the OpenAPI standard requires at least one route to be exposed to make your models consumable, let's see how you can manage this kind
-of issue.
-
-Let's say you have the following entities in your project:
-
-```php
-<?php
-// api/src/Entity/Place.php
-namespace App\Entity;
-
-use Doctrine\ORM\Mapping as ORM;
-
-#[ORM\Entity]
-class Place
-{
-    #[ORM\Id, ORM\Column, ORM\GeneratedValue]
-    private ?int $id = null;
-
-    #[ORM\Column]
-    private string $name = '';
-
-    #[ORM\Column(type: 'float')]
-    private float $latitude = 0;
-
-    #[ORM\Column(type: 'float')]
-    private float $longitude = 0;
-
-    // ...
-}
-```
-
-```php
-<?php
-// api/src/Entity/Weather.php
-namespace App\Entity;
-
-class Weather
-{
-    private float $temperature;
-
-    private float $pressure;
-
-    // ...
-}
-```
-
-We don't save the `Weather` entity in the database, since we want to return the weather in real time when it is queried.
-Because we want to get the weather for a known place, it is more reasonable to query it through a subresource of the `Place` entity, so let's do this:
-
-```php
-<?php
-// api/src/Entity/Place.php
-namespace App\Entity;
-
-use ApiPlatform\Metadata\Get;
-use ApiPlatform\Metadata\Put;
-use ApiPlatform\Metadata\Delete;
-use ApiPlatform\Metadata\GetCollection;
-use ApiPlatform\Metadata\Post;
-use ApiPlatform\Metadata\ApiResource;
-use App\Controller\GetWeather;
-use Doctrine\ORM\Mapping as ORM;
-
-#[ApiResource(
-    operations: [
-        new Get(),
-        new Put(),
-        new Delete(),
-        new Get(name: 'weather', uriTemplate: '/places/{id}/weather', controller: GetWeather::class),
-        new GetCollection(),
-        new Post(),
-    ]
-)]
-#[ORM\Entity]
-class Place
-{
-    // ...
-```
-
-The `GetWeather` controller fetches the weather for the given city and returns an instance of the `Weather` entity.
-This implies that API Platform has to know about this entity, so we will need to make it an API resource too:
-
-```php
-<?php
-// api/src/Entity/Weather.php
-namespace App\Entity;
-
-use ApiPlatform\Metadata\ApiResource;
-
-#[ApiResource]
-class Weather
-{
-    // ...
-```
-
-This will expose the `Weather` model, but also all the default CRUD routes: `GET`, `PATCH`, `DELETE` and `POST`, which is nonsense in our context.
-Since we are required to expose at least one route, let's expose just one:
-
-```php
-<?php
-// api/src/Entity/Weather.php
-namespace App\Entity;
-
-use ApiPlatform\Metadata\ApiResource;
-use ApiPlatform\Metadata\Get;
-
-#[ApiResource(operations: [
-    new Get(controller: SomeRandomController::class)
-])]
-class Weather
-{
-    // ...
-}
-```
-
-This way, we expose a route that will do… nothing. Note that the controller does not even need to exist.
-
-It's almost done, we have just one final issue: our fake item operation is visible in the API docs.
-To remove it, we will need to [decorate the Swagger documentation](openapi.md#overriding-the-openapi-specification).
-Then, remove the route from the decorator:
-
-```php
-<?php
-// src/OpenApi/OpenApiFactory.php
-namespace App\OpenApi;
-
-use ApiPlatform\OpenApi\Factory\OpenApiFactoryInterface;
-use ApiPlatform\OpenApi\OpenApi;
-use ApiPlatform\OpenApi\Model;
-
-final class OpenApiFactory implements OpenApiFactoryInterface
-{
-    private $decorated;
-
-    public function __construct(OpenApiFactoryInterface $decorated)
-    {
-        $this->decorated = $decorated;
-    }
-
-    public function __invoke(array $context = []): OpenApi
-    {
-        $openApi = $this->decorated->__invoke($context);
-
-        $paths = $openApi->getPaths()->getPaths();
-
-        $filteredPaths = new Model\Paths();
-        foreach ($paths as $path => $pathItem) {
-            // If a prefix is configured on API Platform's routes, it must appear here.
-            if ($path === '/weathers/{id}') {
-                continue;
-            }
-            $filteredPaths->addPath($path, $pathItem);
-        }
-
-        return $openApi->withPaths($filteredPaths);
-    }
-}
-```
-
-That's it: your route is gone!
