  /**
   * Builds a cache, which either returns an already-loaded value for a given key or atomically
   * computes or retrieves it using the supplied {@code CacheLoader}. If another thread is currently
   * loading the value for this key, simply waits for that thread to finish and returns its loaded
   * value. Note that multiple threads can concurrently load values for distinct keys.
   *

 * </ul>
 *
 * <h3>Warning about performance</h3>
 *
 * <p>Remember that parameter values for message construction must all be computed eagerly, and
 * autoboxing and varargs array creation may happen as well, even when the verification succeeds and
 * the message ends up unneeded. Performance-sensitive verification checks should continue to use
 * usual form:
 *
 * {@snippet :
 * Bill bill = remoteService.getLastUnpaidBill();

Dans ce cas, vous pouvez désactiver la génération du modèle de réponse en définissant `response_model=None` :

{* ../../docs_src/response_model/tutorial003_05_py310.py hl[7] *}

Cela fera en sorte que FastAPI ignore la génération du modèle de réponse et vous permettra ainsi d’avoir toutes les annotations de type de retour dont vous avez besoin sans que cela n’affecte votre application FastAPI. 🤓

  /**
   * Abstracts away the difference between traversing a graph vs. a tree. For a tree, we just take
   * the next element from the next non-empty iterator; for graph, we need to loop through the next

Then let's create `Hero`, the actual *table model*, with the **extra fields** that are not always in the other models:

* `id`
* `secret_name`

Because `Hero` inherits form `HeroBase`, it **also** has the **fields** declared in `HeroBase`, so all the fields for `Hero` are:

* `id`
* `name`
* `age`
* `secret_name`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:14] hl[12:14] *}

Wenn Sie beispielsweise einen Parameter vom Typ `Hero` deklarieren, wird er aus dem **JSON-Body** gelesen.

Auf die gleiche Weise können Sie es als **Rückgabetyp** der Funktion deklarieren, und dann wird die Form der Daten in der automatischen API-Dokumentation angezeigt.

## Use `Annotated` no tipo do parâmetro `q` { #use-annotated-in-the-type-for-the-q-parameter }

Lembra que eu disse antes que `Annotated` pode ser usado para adicionar metadados aos seus parâmetros na [Introdução aos tipos do Python](../python-types.md#type-hints-with-metadata-annotations)?

Agora é a hora de usá-lo com FastAPI. 🚀

Tínhamos esta anotação de tipo:

```Python
q: str | None = None
```
