## Additional Response with `model` { #additional-response-with-model }

You can pass to your *path operation decorators* a parameter `responses`.

It receives a `dict`: the keys are status codes for each response (like `200`), and the values are other `dict`s with the information for each of them.

* the request body
* the response body
* the JSON body
* the form body
* the file body
* the function body

* the parameter
* the body parameter
* the path parameter
* the query parameter
* the cookie parameter
* the header parameter
* the form parameter
* the function parameter

* the event
* the startup event
* the startup of the server
* the shutdown event
* the lifespan event

### Pydantic의 `exclude_unset` 파라미터 사용하기 { #using-pydantics-exclude-unset-parameter }

부분 업데이트를 받으려면 Pydantic 모델의 `.model_dump()`에서 `exclude_unset` 파라미터를 사용하는 것이 매우 유용합니다.

예: `item.model_dump(exclude_unset=True)`.

이는 `item` 모델을 만들 때 실제로 설정된 데이터만 포함하는 `dict`를 생성하고, 기본값은 제외합니다.
