Keep in mind that dataclasses can't do everything Pydantic models can do.

So, you might still need to use Pydantic models.

But if you have a bunch of dataclasses laying around, this is a nice trick to use them to power a web API using FastAPI. 🤓

///

## Dataclasses in `response_model` { #dataclasses-in-response-model }

You can also use `dataclasses` in the `response_model` parameter:

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```

### 템플릿 컨텍스트 값

다음과 같은 HTML에서:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

...이는 전달한 "컨텍스트" `dict`에서 가져온 `id`를 표시합니다:

```Python
{"id": id}
```

예를 들어, ID가 `42`일 경우, 이는 다음과 같이 렌더링됩니다:

```html
Item ID: 42
```

### 템플릿 `url_for` 인수

Do you want to have an `id` and `email` and not have any `username` in your model? Sure. You can use these same tools.

Do you want to just have a `str`? Or just a `dict`? Or a database class model instance directly? It all works the same way.

You actually don't have users that log in to your application but robots, bots, or other systems, that have just an access token? Again, it all works the same.

Möchten Sie nur ein `str` haben? Oder nur ein `dict`? Oder direkt eine Instanz eines Modells einer Datenbank-Klasse? Es funktioniert alles auf die gleiche Weise.

Sie haben eigentlich keine Benutzer, die sich bei Ihrer Anwendung anmelden, sondern Roboter, Bots oder andere Systeme, die nur über einen Zugriffstoken verfügen? Auch hier funktioniert alles gleich.

## OAuth2 схема безопасности { #oauth2-security-scheme }

Первое изменение — мы объявляем схему безопасности OAuth2 с двумя доступными scopes: `me` и `items`.

Параметр `scopes` получает `dict`, где каждый scope — это ключ, а описание — значение:

{* ../../docs_src/security/tutorial005_an_py310.py hl[63:66] *}

Так как теперь мы объявляем эти scopes, они появятся в документации API при входе/авторизации.
