まずは [仮想環境](../virtual-environments.md) を作成・有効化し、`sqlmodel` をインストールします:

<div class="termy">

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

</div>

## 単一モデルでアプリ作成 { #create-the-app-with-a-single-model }

まずは最も簡単な、単一の SQLModel モデルだけを使うバージョンを作ります。

後で、下記のとおり複数モデルにしてセキュリティと汎用性を高めます。🤓

### モデルの作成 { #create-models }

`SQLModel` をインポートしてデータベースモデルを作成します:

* Automatic data model documentation with [**JSON Schema**](https://json-schema.org/) (as OpenAPI itself is based on JSON Schema).
* Designed around these standards, after a meticulous study. Instead of an afterthought layer on top.

Many packages that simplify it a lot have to make many compromises with the data model, database, and available features. And some of these packages that simplify things too much actually have security flaws underneath.

---

**FastAPI** doesn't make any compromise with any database, data model or tool.

It gives you all the flexibility to choose the ones that fit your project the best.

 * implementations may store cookies in memory; sophisticated ones may use the file system or
 * database to hold accepted cookies. The [cookie storage model][rfc_6265_53] specifies policies for
 * updating and expiring cookies.

## 建立只有單一模型的應用 { #create-the-app-with-a-single-model }

我們先用單一 SQLModel 模型建立這個應用的最簡版。

接著我們會在下方用多個模型來提升安全性與彈性。🤓

### 建立模型 { #create-models }

匯入 `SQLModel` 並建立一個資料庫模型：

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

`Hero` 類別與 Pydantic 模型非常相似（事實上，在底層它就是一個 Pydantic 模型）。

有幾點差異：

* `table=True` 告訴 SQLModel 這是一個「資料表模型」（table model），它應該代表 SQL 資料庫中的一個資料表，而不僅僅是「資料模型」（就像一般的 Pydantic 類別）。
