**FastAPI** fournit un raccourci pour ces cas, lorsque la dépendance est spécifiquement une classe que **FastAPI** va « appeler » pour créer une instance de la classe elle‑même.

Pour ces cas précis, vous pouvez faire ce qui suit :

Au lieu d'écrire :

//// tab | Python 3.10+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

Ce ne serait pas si important dans cet exemple précis, car il s'agit d'un faux fichier en mémoire (avec `io.BytesIO`), mais avec un vrai fichier, il est important de s'assurer qu'il est fermé une fois le travail terminé.

### Gérer les fichiers et async { #files-and-async }

   * {@code key} while the new value was loading then a removal notification will be sent for the
   * new value.
   *
   * <p>If the cache loader associated with this cache is known not to throw checked exceptions,
   * then prefer {@link #getUnchecked} over this method.
   *
   * @throws ExecutionException if a checked exception was thrown while loading the value. ({@code
   *     ExecutionException} is thrown <a

```

sería equivalente a:

```Python
UserInDB(**user_in.model_dump())
```

...porque `user_in.model_dump()` es un `dict`, y luego hacemos que Python lo "desempaquete" al pasarlo a `UserInDB` con el prefijo `**`.

Así, obtenemos un modelo Pydantic a partir de los datos en otro modelo Pydantic.

If you prefer to use the `uvicorn` command directly:
