### 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.

그 다음 이를 사용해 (요청에서 전송되어) 설정된 데이터만 포함하고 기본값은 생략한 `dict`를 만들 수 있습니다:

{* ../../docs_src/body_updates/tutorial002_py310.py hl[32] *}

   * @param mayInterruptIfRunning {@code true} if the thread executing this task should be
   *     interrupted; otherwise, in-progress tasks are allowed to complete, but the step will be
   *     cancelled regardless
   * @return {@code false} if the step could not be cancelled, typically because it has already
   *     completed normally; {@code true} otherwise
