* Validate that there is an `item_id` in the path for `GET` and `PUT` requests.
* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
    * If it is not, the client will see a useful, clear error.
* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests.
    * As the `q` parameter is declared with `= None`, it is optional.

If you go to the `/docs` API UI, you will see that it is now updated, and it won't expect to receive the `id` from the client when creating a hero, etc.

## Recapitulando

* **Daten umzuwandeln**: aus der Anfrage in den erforderlichen Typ.
* **Daten zu validieren**: aus jeder Anfrage:
    * **Automatische Fehler** generieren, die an den Client zurückgegeben werden, wenn die Daten ungültig sind.
* Die API mit OpenAPI zu **dokumentieren**:
    * Die dann von den Benutzeroberflächen der automatisch generierten interaktiven Dokumentation verwendet wird.

* Valider que `item_id` existe dans le chemin des requêtes `GET` et `PUT`.
* Valider que `item_id` est de type `int` pour les requêtes `GET` et `PUT`.
    * Si ce n'est pas le cas, le client voit une erreur utile et claire.
* Vérifier qu'il existe un paramètre de requête facultatif nommé `q` (comme dans `http://127.0.0.1:8000/items/foo?q=somequery`) pour les requêtes `GET`.
