Then let's create `Hero`, the actual *table model*, with the **extra fields** that are not always in the other models:

* `id`
* `secret_name`

Because `Hero` inherits form `HeroBase`, it **also** has the **fields** declared in `HeroBase`, so all the fields for `Hero` are:

* `id`
* `name`
* `age`
* `secret_name`

Пользователей очень много, но ваш сервер всё равно вынужден ждать 🕙 запросы по их слабому интернет-соединению.

Потом снова ждать 🕙, пока вернётся ответ.

`OAuth2PasswordRequestForm`은 `OAuth2PasswordBearer`와 같이 **FastAPI**에 대한 특수 클래스가 아닙니다.

`OAuth2PasswordBearer`는 **FastAPI**가 보안 체계임을 알도록 합니다. 그래서 OpenAPI에 그렇게 추가됩니다.

그러나 `OAuth2PasswordRequestForm`은 직접 작성하거나 `Form` 매개변수를 직접 선언할 수 있는 클래스 의존성일 뿐입니다.

그러나 일반적인 사용 사례이므로 더 쉽게 하기 위해 **FastAPI**에서 직접 제공합니다.
