## Agregar `dependencies` al decorador de *path operation* { #add-dependencies-to-the-path-operation-decorator }

El decorador de *path operation* recibe un argumento opcional `dependencies`.

Debe ser una `list` de `Depends()`:

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[19] *}

Tener `str | None` permitirá que tu editor te dé un mejor soporte y detecte errores.

## Validaciones adicionales { #additional-validation }

Vamos a hacer que, aunque `q` sea opcional, siempre que se proporcione, su longitud no exceda los 50 caracteres.

### Importar `Query` y `Annotated` { #import-query-and-annotated }

## Adicione `dependencies` ao *decorador da operação de rota* { #add-dependencies-to-the-path-operation-decorator }

O *decorador da operação de rota* recebe um argumento opcional `dependencies`.

`OAuth2PasswordRequestForm` est une dépendance de classe qui déclare un corps de formulaire avec :

* Le `username`.
* Le `password`.
* Un champ optionnel `scope` sous forme d'une grande chaîne, composée de chaînes séparées par des espaces.
* Un `grant_type` optionnel.

/// tip | Astuce

La spécification OAuth2 exige en réalité un champ `grant_type` avec la valeur fixe `password`, mais `OAuth2PasswordRequestForm` ne l'impose pas.
