Por lo tanto, puedes buscar esa excepción específica dentro de la dependencia con `except SomeException`.

Del mismo modo, puedes usar `finally` para asegurarte de que los pasos de salida se ejecuten, sin importar si hubo una excepción o no.

## Sub-dependencias con `yield` { #sub-dependencies-with-yield }

/// note | Nota

Si usas una clase de response sin media type, FastAPI esperará que tu response no tenga contenido, por lo que no documentará el formato del response en su OpenAPI generado.

## Usa `ORJSONResponse` { #use-orjsonresponse }

Sin un sistema de validación de datos, tendrías que hacer todas las comprobaciones a mano, en código.

Estas funcionalidades son para lo que fue creado Marshmallow. Es un gran paquete, y lo he usado mucho antes.
