!!! tip
    但是依然建议你使用上面提到的主意，使用多个类而不是这些参数。

    这是因为即使使用 `response_model_include` 或 `response_model_exclude` 来省略某些属性，在应用程序的 OpenAPI 定义（和文档）中生成的 JSON Schema 仍将是完整的模型。

    这也适用于作用类似的 `response_model_by_alias`。

```Python hl_lines="31  37"
{!../../../docs_src/response_model/tutorial005.py!}
```

!!! tip
    `{"name", "description"}` 语法创建一个具有这两个值的 `set`。

    等同于 `set(["name", "description"])`。

    それでも、これらのパラメータではなく、複数のクラスを使用して、上記のようなアイデアを使うことをおすすめします。

    これは`response_model_include`や`response_mode_exclude`を使用していくつかの属性を省略しても、アプリケーションのOpenAPI（とドキュメント）で生成されたJSON Schemaが完全なモデルになるからです。

    同様に動作する`response_model_by_alias`にも当てはまります。

```Python hl_lines="31 37"
{!../../../docs_src/response_model/tutorial005.py!}
```

!!! tip "豆知識"
    `{"name", "description"}`の構文はこれら２つの値をもつ`set`を作成します。

O que mais se aproxima é `item_query`.

Mas ainda você precisa que o nome seja exatamente `item-query`...

Então você pode declarar um `alias`, e esse apelido (alias) que será utilizado para encontrar o valor do parâmetro:

```Python hl_lines="9"
{!../../../docs_src/query_params_str_validations/tutorial009.py!}
```
