`File`  — це клас, який безпосередньо успадковує `Form`.

Але пам’ятайте, що коли Ви імпортуєте `Query`, `Path`, `File` та інші з `fastapi`, це насправді функції, які повертають спеціальні класи.

そして、さらに多くのパラメータを`Query`に渡すことができます。この場合、文字列に適用される、`max_length`パラメータを指定します。

```Python
q: Union[str, None] = Query(default=None, max_length=50)
```

これにより、データを検証し、データが有効でない場合は明確なエラーを表示し、OpenAPIスキーマの　*path operation* にパラメータを記載します。

## バリデーションをさらに追加する

パラメータ`min_length`も追加することができます:
