가장 중요한 건, 표준 파이썬 타입을 한 곳에서(클래스를 더하거나, 데코레이터 사용하는 대신) 사용함으로써 **FastAPI**가 당신을 위해 많은 일을 해준다는 사실이죠.

kubeadm has been updated to drop an unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10 as the CI build jobs what build images correctly updates those. The CI jobs for master update the ci-cross/latest location, so if you are looking for latest master builds, then the correct parameter to use would be ci-cross/latest....

APIに求められる他の大きな機能として、<abbr title="Pythonデータの読み込みと変換">受信したリクエストデータのパース</abbr>があります。

WebargsはFlaskをはじめとするいくつかのフレームワークの上にそれを提供するために作られたツールです。

 * ## Force a Cache Response
 *
 * Sometimes you'll want to show resources if they are available immediately, but not otherwise.
 * This can be used so your application can show *something* while waiting for the latest data to be
 * downloaded. To restrict a request to locally-cached resources, add the `only-if-cached`
 * directive:
 *
 * ```java
 * Request request = new Request.Builder()

type WalkOptions struct {
	Filter       func(info FileInfo) bool // return WalkFilter returns 'true/false'
	Marker       string                   // set to skip until this object
	LatestOnly   bool                     // returns only latest versions for all matching objects
	AskDisks     string                   // dictates how many disks are being listed

        this.shareName = shareName;
        this.serverAddress = serverAddress;
        this.serviceType = serviceType;
        this.version = WitnessVersion.VERSION_2;  // Use latest by default
        this.registrationTime = System.currentTimeMillis();
        this.sequenceNumber = new AtomicLong(0);
        this.state = WitnessRegistrationState.REGISTERING;
        this.lastHeartbeat = registrationTime;

此处，在应用程序启动事件中，我们创建了表。

而对于生产环境，您可能会用一个能够在启动应用程序之前运行的迁移脚本。🤓

SQLModel 将会拥有封装 Alembic 的迁移工具，但目前您可以直接使用 <a href="https://alembic.sqlalchemy.org/en/latest/" class="external-link" target="_blank">Alembic</a>。

### 创建 Hero 类

因为每个 SQLModel 模型同时也是一个 Pydantic 模型，所以您可以在与 Pydantic 模型相同的**类型注释**中使用它。

例如，如果您声明一个类型为 `Hero` 的参数，它将从 **JSON 主体**中读取数据。
