The dictionary in `openapi_extra` will be deeply merged with the automatically generated OpenAPI schema for the *path operation*.

So, you could add additional data to the automatically generated schema.

For example, you could decide to read and validate the request with your own code, without using the automatic features of FastAPI with Pydantic, but you could still want to define the request in the OpenAPI schema.

You could do that with `openapi_extra`:

        return int(sip.Sum64() % uint64(cardinality))
}
```

Input for the key is the object name specified in `PutObject()`, returns a unique index. This index is one of the erasure sets where the object will reside. This function is a consistent hash for a given object name i.e for a given object name the index returned is always the same.

La primera siempre será utilizada ya que el path coincide primero.

## Valores predefinidos { #predefined-values }

Si tienes una *path operation* que recibe un *path parameter*, pero quieres que los valores posibles válidos del *path parameter* estén predefinidos, puedes usar un <abbr title="Enumeration – Enumeración">`Enum`</abbr> estándar de Python.

Now let's **refactor** this app a bit to increase **security** and **versatility**.

If you check the previous app, in the UI you can see that, up to now, it lets the client decide the `id` of the `Hero` to create. 😱

We shouldn't let that happen, they could overwrite an `id` we already have assigned in the DB. Deciding the `id` should be done by the **backend** or the **database**, **not by the client**.

* **function**: es la función debajo del "decorador" (debajo de `@app.get("/")`).

{* ../../docs_src/first_steps/tutorial001_py39.py hl[7] *}

Esta es una función de Python.

Será llamada por **FastAPI** cuando reciba un request en la URL "`/`" usando una operación `GET`.

En este caso, es una función `async`.

También podrías definirla como una función normal en lugar de `async def`:

## Add Labels to PRs

The same GitHub Action <a href="https://github.com/tiangolo/latest-changes" class="external-link" target="_blank">latest-changes</a> uses one label in the PR to decide the section in the release notes to put this PR in.

Make sure you use a supported label from the <a href="https://github.com/tiangolo/latest-changes#using-labels" class="external-link" target="_blank">latest-changes list of labels</a>:

Agora vamos **refatorar** este app um pouco para aumentar a **segurança** e **versatilidade**.

Se você verificar o app anterior, na interface você pode ver que, até agora, ele permite que o cliente decida o `id` do `Hero` a ser criado. 😱
