# 응답 모델

어떤 *경로 작동*이든 매개변수 `response_model`를 사용하여 응답을 위한 모델을 선언할 수 있습니다:

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

{* ../../docs_src/response_model/tutorial001.py hl[17] *}

/// note | 참고

`response_model`은 "데코레이터" 메소드(`get`, `post`, 등)의 매개변수입니다. 모든 매개변수들과 본문(body)처럼 *경로 작동 함수*가 아닙니다.

///

Pydantic 모델 어트리뷰트를 선언한 것과 동일한 타입을 수신하므로 Pydantic 모델이 될 수 있지만, `List[Item]`과 같이 Pydantic 모델들의 `list`일 수도 있습니다.
