* **データベースモデル**はおそらくハッシュ化されたパスワードが必要になるでしょう。

/// danger | 危険

ユーザーの平文のパスワードは絶対に保存しないでください。常に認証に利用可能な「安全なハッシュ」を保存してください。

知らない方は、[セキュリティの章](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}で「パスワードハッシュ」とは何かを学ぶことができます。

## 複数のモデル

ここでは、パスワードフィールドをもつモデルがどのように見えるのか、また、どこで使われるのか、大まかなイメージを紹介します:

## 文档字符串（`docstring`）

描述内容比较长且占用多行时，可以在函数的 <abbr title="函数中作为第一个表达式，用于文档目的的一个多行字符串（并没有被分配个任何变量）">docstring</abbr> 中声明*路径操作*的描述，**FastAPI** 支持从文档字符串中读取描述内容。

文档字符串支持 <a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a>，能正确解析和显示 Markdown 的内容，但要注意文档字符串的缩进。

{* ../../docs_src/path_operation_configuration/tutorial004.py hl[19:27] *}
