そして、Gunicorn互換の**Uvicornワーカー**クラスが、FastAPIが使えるように、Gunicornから送られてきたデータをASGI標準に変換する役割を担います。

## GunicornとUvicornをインストールする

<div class="termy">

```console
$ pip install "uvicorn[standard]" gunicorn

---> 100%
```

</div>

これによりUvicornと（高性能を得るための）標準（`standard`）の追加パッケージとGunicornの両方がインストールされます。

## UvicornのワーカーとともにGunicornを実行する

Gunicornを以下のように起動させることができます:

## 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
```

## `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

if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).

  The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for

              <dt>manual</dt>
              <dd>user must manually download and install the dependency.</dd>
            </dl>

<p>
The interpretation of the ImportPath is implementation-dependent but
it is typically a substring of the full file name of the compiled
package and may be relative to a repository of installed packages.

<p>
Implementation restriction: A compiler may restrict ImportPaths to
non-empty strings using only characters belonging to
