/// tip | Підказка

Ви також можете використовувати `Enum`-и, так само як і з [Path Parameters](path-params.md#predefined-values){.internal-link target=_blank}.

* `limit`, необязательный `int`.

/// tip | Подсказка

Вы можете использовать класс `Enum` также, как ранее применяли его с [Path-параметрами](path-params.md#_7){.internal-link target=_blank}.

## Visão global

Primeiro, vamos olhar rapidamente as partes que mudam dos exemplos do **Tutorial - Guia de Usuário** para [OAuth2 com Senha (e hash), Bearer com tokens JWT](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Agora utilizando escopos OAuth2:

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:125,129:135,140,156] *}

Agora vamos revisar essas mudanças passo a passo.

* **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:

{* ../../docs_src/extra_models/tutorial001.py hl[9,11,16,22,24,29:30,33:35,40:41] *}

)
```

/// info | Informação

Para uma explicação mais completa de `**user_dict`, verifique [a documentação para **Extra Models**](../extra-models.md#about-user_indict){.internal-link target=_blank}.

## Retorne o token

A resposta do endpoint `token` deve ser um objeto JSON.
