### Utiliser le paramètre `response_model_exclude_unset` { #use-the-response-model-exclude-unset-parameter }

Vous pouvez définir le paramètre du *décorateur de chemin d'accès* `response_model_exclude_unset=True` :

{* ../../docs_src/response_model/tutorial004_py310.py hl[22] *}

* The `emptyDir.sizeLimit` field is now correctly omitted from API requests and responses when unset. ([#50163](https://github.com/kubernetes/kubernetes/pull/50163), [@jingxu97](https://github.com/jingxu97))

#### kubectl:

    /**
     * Return the attributes of this file. Attributes are represented as a
     * bitset that must be masked with {@code ATTR_*} constants to determine
     * if they are set or unset. The value returned is suitable for use with
     * the {@code setAttributes()} method.
     *
     * @return the {@code ATTR_*} attributes associated with this file

하지만 실제로 저장되지 않았을 경우 결과에서 이를 생략하고 싶을 수 있습니다.

예를 들어, NoSQL 데이터베이스에 많은 선택적 속성이 있는 모델이 있지만, 기본값으로 가득 찬 매우 긴 JSON 응답을 보내고 싶지 않습니다.

### `response_model_exclude_unset` 매개변수 사용 { #use-the-response-model-exclude-unset-parameter }

*경로 처리 데코레이터* 매개변수 `response_model_exclude_unset=True`로 설정할 수 있습니다:

{* ../../docs_src/response_model/tutorial004_py310.py hl[22] *}

그러면 이러한 기본값은 응답에 포함되지 않고, 실제로 설정된 값만 포함됩니다.

* `tags: List[str] = []` 默认值为一个空列表：`[]`。

但如果它们并没有被实际存储，你可能希望在结果中省略这些默认值。

例如，当你在 NoSQL 数据库中保存了具有许多可选属性的模型，但又不想发送充满默认值的冗长 JSON 响应。

### 使用 `response_model_exclude_unset` 参数 { #use-the-response-model-exclude-unset-parameter }

你可以设置*路径操作装饰器*参数 `response_model_exclude_unset=True`：

{* ../../docs_src/response_model/tutorial004_py310.py hl[22] *}

这样响应中将不会包含那些默认值，而只包含实际设置的值。

- Made legacy watch calls (`ResourceVersion` = 0 or unset) that generate init-events weigh higher in `API Priority and Fairness (APF)` seat usage. Properly accounting for their cost protects the API server from CPU overload. Users might see increased throttling of such calls as a result. ([#134601](https...

- Added audienceMatchPolicy field to AuthenticationConfiguration and support for configuring multiple audiences.
  The "audienceMatchPolicy" can be empty (or unset) when a single audience is specified in the "audiences" field.

- Added support for specifying `controlplane` or `cluster` egress selectors in JWT authenticators via the `issuer.egressSelectorType` field in the `AuthenticationConfiguration.jwt` array. If unset, the previous behavior of using no egress selector is preserved. This functionality requires the `StructuredAuthenticationConfigurationEgressSelector` beta feature gate (enabled by default).

#### Storage

- The `Node.Status.Volumes.Attached.DevicePath` field is now unset for CSI volumes. You must update any external controllers that depend on this field. ([#75799](https://github.com/kubernetes/kubernetes/pull/75799), [@msau42](https://github.com/msau42))
