/// info | 情報

`separate_input_output_schemas` のサポートは FastAPI `0.102.0` で追加されました。🤓

///

{* ../../docs_src/separate_openapi_schemas/tutorial002_py310.py hl[10] *}

### ドキュメントで入力・出力に同一スキーマを使用 { #same-schema-for-input-and-output-models-in-docs }

これでモデルの入力と出力は単一のスキーマ、`Item` のみになり、`description` は **必須ではありません**:

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image05.png">

query_extractor(["query_extractor"])
query_or_cookie_extractor(["query_or_cookie_extractor"])

read_query["/items/"]

query_extractor --> query_or_cookie_extractor --> read_query
```

## 同じ依存関係の複数回の使用 { #using-the-same-dependency-multiple-times }

依存関係の1つが同じ*path operation*に対して複数回宣言されている場合、例えば、複数の依存関係が共通のサブ依存関係を持っている場合、**FastAPI** はリクエストごとに1回だけそのサブ依存関係を呼び出します。
