## パラメータを非推奨にする { #deprecating-parameters }

さて、このパラメータが気に入らなくなったとしましょう。

それを使っているクライアントがいるので、しばらくは残しておく必要がありますが、ドキュメントには<dfn title="廃止予定、使用は推奨されません">廃止予定</dfn>と明記しておきたいです。

その場合、`Query`にパラメータ`deprecated=True`を渡します:

{* ../../docs_src/query_params_str_validations/tutorial010_an_py310.py hl[19] *}

ドキュメントは以下のようになります:
