Si capturas una excepción en una dependencia con `yield`, a menos que estés lanzando otra `HTTPException` o similar, **deberías volver a lanzar la excepción original**.

Puedes volver a lanzar la misma excepción usando `raise`:

{* ../../docs_src/dependencies/tutorial008d_an_py310.py hl[17] *}

# Devolver una Response Directamente { #return-a-response-directly }

Cuando creas una *path operation* en **FastAPI**, normalmente puedes devolver cualquier dato desde ella: un `dict`, una `list`, un modelo de Pydantic, un modelo de base de datos, etc.

Si declaras un [Response Model](../tutorial/response-model.md) FastAPI lo usará para serializar los datos a JSON, usando Pydantic.

Pero en algunos casos necesitas devolver un código de estado diferente al predeterminado.

## Caso de uso { #use-case }

Por ejemplo, imagina que quieres devolver un código de estado HTTP de "OK" `200` por defecto.

Pero si los datos no existieran, quieres crearlos y devolver un código de estado HTTP de "CREATED" `201`.

Por ejemplo, podría ser algo así:

{* ../../docs_src/custom_response/tutorial004_py310.py hl[7,21,23] *}

En este ejemplo, la función `generate_html_response()` ya genera y devuelve una `Response` en lugar de devolver el HTML en un `str`.

Al devolver el resultado de llamar a `generate_html_response()`, ya estás devolviendo una `Response` que sobrescribirá el comportamiento por defecto de **FastAPI**.
