## 安装 `SQLModel`

首先，确保您创建并激活了[虚拟环境](../virtual-environments.md){.internal-link target=_blank}，然后安装了 `sqlmodel` :

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

## 创建含有单一模型的应用程序

我们首先创建应用程序的最简单的第一个版本，只有一个 **SQLModel** 模型。

稍后我们将通过下面的**多个模型**提高其安全性和多功能性。🤓

### 创建模型

导入 `SQLModel` 并创建一个数据库模型：

    /** The key of the message: Delete */
    public static final String LABELS_plugin_delete = "{labels.plugin_delete}";

    /** The key of the message: Install */
    public static final String LABELS_plugin_install = "{labels.plugin_install}";

    /** The key of the message: Install Plugin */
    public static final String LABELS_plugin_install_title = "{labels.plugin_install_title}";

    /** The key of the message: Jar File */

## `SQLModel` 설치하기

먼저, [가상 환경](../virtual-environments.md){.internal-link target=_blank}을 생성하고 활성화한 다음, `sqlmodel`을 설치하세요:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

## 단일 모델로 애플리케이션 생성하기

우선 단일 **SQLModel** 모델을 사용하여 애플리케이션의 가장 간단한 첫 번째 버전을 생성해보겠습니다.

이후 **다중 모델**을 추가하여 보안과 유연성을 강화할 것입니다. 🤓

### 모델 생성하기

	public fun equals (Ljava/lang/Object;)Z
	public final fun get (Ljava/lang/String;)Ljava/lang/String;
	public final fun getDate (Ljava/lang/String;)Ljava/util/Date;
	public final fun getInstant (Ljava/lang/String;)Ljava/time/Instant;
	public fun hashCode ()I
	public fun iterator ()Ljava/util/Iterator;
	public final fun name (I)Ljava/lang/String;
	public final fun names ()Ljava/util/Set;
	public final fun newBuilder ()Lokhttp3/Headers$Builder;

Sie können die *Pfadoperationen* für dieses Modul mit `APIRouter` erstellen.

### `APIRouter` importieren { #import-apirouter }

Sie importieren ihn und erstellen eine „Instanz“ auf die gleiche Weise wie mit der Klasse `FastAPI`:

{* ../../docs_src/bigger_applications/app_an_py39/routers/users.py hl[1,3] title["app/routers/users.py"] *}

    OkHttp 2 the built-in disk cache is the only supported response cache.

- The in-tree GCE PD plugin `kubernetes.io/gce-pd` is now deprecated and will be removed in 1.21. Users that self-deploy Kubernetes on GCP should enable CSIMigration + CSIMigrationGCE features and install the GCE PD CSI Driver (https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver) to avoid disruption to existing Pod and PVC objects at that time. Users should start using the GCE PD CSI CSI Driver directly for any new volumes. (...
