Dieser ganze Erneuerungsprozess, während die Anwendung weiterhin bereitgestellt wird, ist einer der Hauptgründe, warum Sie ein **separates System zur Verarbeitung von HTTPS** mit einem TLS-Terminierungsproxy haben möchten, anstatt einfach die TLS-Zertifikate direkt mit dem Anwendungsserver zu verwenden (z. B. Uvicorn).

## 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：

これを行うには、`return`の代わりに`yield`を使い、その後に追加のステップを書きます。

/// tip | 豆知識

`yield`は必ず一度だけ使用するようにしてください。

///

/// info | 情報

これを動作させるには、**Python 3.7** 以上を使用するか、**Python 3.6** では"backports"をインストールする必要があります:

```
pip install async-exit-stack async-generator
```
