<p>
            We check the binary compatibility by comparing the current code’s binary interfaces
            against THE LATEST VERSION WHICH IS RELEASED FROM RELEASE BRANCH (from `released-version.json` on this branch)
            AND LOWER THAN CURRENT BASE VERSION (from `version.txt` on this branch).

    FastAPI는 이를 위해 Pydantic 모델의 `.dict()`의 <a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank"> `exclude_unset` 매개변수</a>를 사용합니다.

  optional string status = 2;

  // The last time this condition was updated.
  optional k8s.io.apimachinery.pkg.apis.meta.v1.Time lastUpdateTime = 6;

  // Last time the condition transitioned from one status to another.
  optional k8s.io.apimachinery.pkg.apis.meta.v1.Time lastTransitionTime = 7;

    FastAPI 通过 Pydantic 模型的 `.dict()` 配合 <a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank">该方法的 `exclude_unset` 参数</a> 来实现此功能。

# スキーマの追加 - 例

JSON Schemaに追加する情報を定義することができます。

一般的なユースケースはこのドキュメントで示されているように`example`を追加することです。

JSON Schemaの追加情報を宣言する方法はいくつかあります。

## Pydanticの`schema_extra`

<a href="https://docs.pydantic.dev/latest/concepts/json_schema/#schema-customization" class="external-link" target="_blank">Pydanticのドキュメント: スキーマのカスタマイズ</a>で説明されているように、`Config`と`schema_extra`を使ってPydanticモデルの例を宣言することができます:

```Python hl_lines="15 16 17 18 19 20 21 22 23"

* WebSocket support.
* In-process background tasks.
* Startup and shutdown events.
* Test client built on HTTPX.
* CORS, GZip, Static Files, Streaming responses.
* Session and Cookie support.
* 100% test coverage.
* 100% type annotated codebase.
* Few hard dependencies.

Starlette is currently the fastest Python framework tested. Only surpassed by Uvicorn, which is not a framework, but a server.

  // +optional
  optional int64 observedGeneration = 3;

  // Last time the condition transitioned from one status to another.
  // +required
  optional k8s.io.apimachinery.pkg.apis.meta.v1.Time lastTransitionTime = 4;

  // The reason for the condition's last transition.
  // +required
  optional string reason = 5;

## Pydantic `Settings`

Fortunately, Pydantic provides a great utility to handle these settings coming from environment variables with <a href="https://docs.pydantic.dev/latest/usage/pydantic_settings/" class="external-link" target="_blank">Pydantic: Settings management</a>.

### Install `pydantic-settings`

First, install the `pydantic-settings` package:
