次に、[http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc)にアクセスします。

先ほどとは異なる、自動生成された対話的APIドキュメントが表示されます（[ReDoc](https://github.com/Rebilly/ReDoc)によって提供）:

### OpenAPI { #openapi }

**FastAPI**は、APIを定義するための**OpenAPI**標準規格を使用して、すべてのAPIの「スキーマ」を生成します。

#### 「スキーマ」 { #schema }

Інтегрувати інструменти інтерфейсу на основі стандартів:

* [Інтерфейс Swagger](https://github.com/swagger-api/swagger-ui)
* [ReDoc](https://github.com/Rebilly/ReDoc)

Ці два було обрано через те, що вони досить популярні та стабільні, але, виконавши швидкий пошук, ви можете знайти десятки додаткових альтернативних інтерфейсів для OpenAPI (які можна використовувати з **FastAPI**).

Because all the **fields actually change** (the type now includes `None` and they now have a default value of `None`), we need to **re-declare** them.

We don't really need to inherit from `HeroBase` because we are re-declaring all the fields. I'll leave it inheriting just for consistency, but this is not necessary. It's more a matter of personal taste. 🤷

The fields of `HeroUpdate` are:

  //    possible to the thing right before the try. You could have
  //    guard.leave(), but that's a little odd as well because the
  //    guard doesn't have anything to do with leaving. You can't
  //    really enforce that the guard you're leaving is the same one
  //    you entered with, and it doesn't actually matter.
  //
  // 2. Since you can enter the monitor without a guard at all, some
