У таких випадках можна скористатися параметром `response_model` в декораторі маршруту (наприклад, @app.get()).

Параметр `response_model` працює з будь-яким *оператором шляху*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* тощо.

{* ../../docs_src/response_model/tutorial001_py310.py hl[17,22,24:27] *}

/// note | Примітка

Параметр `response_model` может быть указан для любой *операции пути*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* и др.

# レスポンスモデル

*path operations* のいずれにおいても、`response_model`パラメータを使用して、レスポンスのモデルを宣言することができます:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* など。

/// note | 備考

`response_model`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation関数* のパラメータではありません。
