Обратите внимание, что входная модель по-прежнему валидируется.

Таким образом, если вы хотите получать частичные обновления, в которых могут быть опущены все атрибуты, вам необходимо иметь модель, в которой все атрибуты помечены как необязательные (со значениями по умолчанию или `None`).

     * Note that the artifact need not actually exist yet at the returned location,
     * the path merely indicates where the artifact would eventually be stored.
     *
     * @param session The session to use, must not be {@code null}.
     * @param local The local repository, must not be {@code null}.
     * @param artifact The artifact for which to determine the path, must not be {@code null}.

It is not acceptable to introduce new properties on a task, extension or domain object that use plain getters and setters.  It is also not acceptable to add setters that take a Provider.

Vous pouvez également déclarer des paramètres body comme étant optionnels, en leur assignant une valeur par défaut à `None` :

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note

Notez que, dans ce cas, le paramètre `item` provenant du `Body` est optionnel (sa valeur par défaut est `None`).

The query parameter `q` is of type `str | None`, that means that it's of type `str` but could also be `None`, and indeed, the default value is `None`, so FastAPI will know it's not required.

/// note

FastAPI will know that the value of `q` is not required because of the default value `= None`.

Having `str | None` will allow your editor to give you better support and detect errors.

デフォルト値`None`を`Query(default=None)`に置き換える必要があるので、`Query`の最初の引数はデフォルト値を定義するのと同じです。

なので:

```Python
q: Optional[str] = Query(default=None)
```

...を以下と同じようにパラメータをオプションにします:

```Python
q: Optional[str] = None
```

しかし、これはクエリパラメータとして明示的に宣言しています。

FastAPIは以下の部分を気にすることを覚えておいてください:
