Comme `needy` est un paramètre requis, vous devez le définir dans l'URL :

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

... cela fonctionnerait :

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

### Pydantic의 `exclude_unset` 파라미터 사용하기 { #using-pydantics-exclude-unset-parameter }

부분 업데이트를 받으려면 Pydantic 모델의 `.model_dump()`에서 `exclude_unset` 파라미터를 사용하는 것이 매우 유용합니다.

예: `item.model_dump(exclude_unset=True)`.

이는 `item` 모델을 만들 때 실제로 설정된 데이터만 포함하는 `dict`를 생성하고, 기본값은 제외합니다.

그 다음 이를 사용해 (요청에서 전송되어) 설정된 데이터만 포함하고 기본값은 생략한 `dict`를 만들 수 있습니다:

# Sub Aplicações - Montagens { #sub-applications-mounts }

Se você precisar ter duas aplicações FastAPI independentes, cada uma com seu próprio OpenAPI e suas próprias interfaces de documentação, você pode ter um aplicativo principal e "montar" uma (ou mais) sub-aplicações.
