There's a whole chapter here in the documentation about it, you can read it at [Additional Responses in OpenAPI](additional-responses.md){.internal-link target=_blank}.

## OpenAPI Extra { #openapi-extra }

When you declare a *path operation* in your application, **FastAPI** automatically generates the relevant metadata about that *path operation* to be included in the OpenAPI schema.

Arreglaremos estas cosas añadiendo unos **modelos extra**. Aquí es donde SQLModel brillará. ✨

### Crear Múltiples Modelos

En **SQLModel**, cualquier clase de modelo que tenga `table=True` es un **modelo de tabla**.

Y cualquier clase de modelo que no tenga `table=True` es un **modelo de datos**, estos son en realidad solo modelos de Pydantic (con un par de características extra pequeñas). 🤓

     * @param offset
     *            The starting offset at which the SMB header begins.
     * @param length
     *            The length of the data to verify
     * @param extraPad
     *            extra padding to include in signature
     * @param msg
     *            The message to verify
     * @return whether verification was unsuccessful

* **Uvicorn**:
    * Tendrá el mejor rendimiento, ya que no tiene mucho código extra aparte del propio servidor.

## Sobre segurança, APIs e documentos

Ocultar suas interfaces de usuário de documentação na produção *não deveria* ser a maneira de proteger sua API.

Isso não adiciona nenhuma segurança extra à sua API; as *operações de rotas* ainda estarão disponíveis onde estão.

Se houver uma falha de segurança no seu código, ela ainda existirá.
