- CEL regex patterns in x-kubernetes-valiation rules are compiled when CRDs are created/updated if the pattern is provided as a string constant in the expression. Any regex compile errors are reported as a CRD create/update validation error. ([#108617](https://github.com/kubernetes/kubernetes/pull/108617), [@jpbetz](https://github.com/jpbetz))

# 쿼리 매개변수와 문자열 검증 { #query-parameters-and-string-validations }

**FastAPI**를 사용하면 매개변수에 대한 추가 정보 및 검증을 선언할 수 있습니다.

이 애플리케이션을 예로 들어보겠습니다:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

쿼리 매개변수 `q`는 `str | None` 자료형입니다. 즉, `str` 자료형이지만 `None` 역시 될 수 있음을 뜻하고, 실제로 기본값은 `None`이기 때문에 FastAPI는 이 매개변수가 필수가 아니라는 것을 압니다.

/// note | 참고

FastAPI는 `q`의 기본값이 `= None`이기 때문에 필수가 아님을 압니다.

# クエリパラメータと文字列の検証 { #query-parameters-and-string-validations }

**FastAPI** ではパラメータの追加情報とバリデーションを宣言することができます。

以下のアプリケーションを例にしてみましょう:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

クエリパラメータ `q` は `str | None` 型で、`str` 型ですが `None` にもなり得ることを意味し、実際にデフォルト値は `None` なので、FastAPIはそれが必須ではないと理解します。

/// note | 備考

FastAPIは、 `q` はデフォルト値が `= None` であるため、必須ではないと理解します。

`str | None` を使うことで、エディターによるより良いサポートとエラー検出を可能にします。
