**FastAPI** использует их "под капотом" с этой целью.

## Зависимости с `yield` и `HTTPException`

Вы видели, что можно использовать зависимости с `yield` совместно с блоком `try`, отлавливающие исключения.

Таким же образом вы можете поднять исключение `HTTPException` или что-то подобное в завершающем коде, после `yield`.

The `HeroUpdate` *data model* is somewhat special, it has **all the same fields** that would be needed to create a new hero, but all the fields are **optional** (they all have a default value). This way, when you update a hero, you can send just the fields that you want to update.

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.
