Auf diese Weise erhalten wir ein Pydantic-Modell aus den Daten eines anderen Pydantic-Modells.

#### Ein `dict` entpacken und zusätzliche Schlüsselwort-Argumente { #unpacking-a-dict-and-extra-keywords }

Und dann fügen wir das zusätzliche Schlüsselwort-Argument `hashed_password=hashed_password` hinzu, wie in:

```Python
UserInDB(**user_in.model_dump(), hashed_password=hashed_password)
```

... was so ist wie:

                Arguments.of(NbtException.ERR_NAM_SRVC, NbtException.FMT_ERR, "ERR_NAM_SRVC/FMT_ERR: Format ErrorUnknown error code: 1"),
                Arguments.of(NbtException.ERR_NAM_SRVC, NbtException.SRV_ERR, "ERR_NAM_SRVC/Unknown error code: 2"),
                Arguments.of(NbtException.ERR_NAM_SRVC, NbtException.IMP_ERR, "ERR_NAM_SRVC/Unknown error code: 4"),

### `Union` en Python 3.10 { #union-in-python-3-10 }

Dans cet exemple, nous passons `Union[PlaneItem, CarItem]` comme valeur de l'argument `response_model`.

Comme nous le passons comme valeur d'un argument au lieu de l'utiliser dans une annotation de type, nous devons utiliser `Union` même en Python 3.10.

from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

`app.add_middleware()` empfängt eine Middleware-Klasse als erstes Argument und dann alle weiteren Argumente, die an die Middleware übergeben werden sollen.

## Integrierte Middleware { #integrated-middlewares }

from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

`app.add_middleware()` receives a middleware class as the first argument and any additional arguments to be passed to the middleware.

## Integrated middlewares { #integrated-middlewares }

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.
