### Utilizando o nome da *função de operação de rota* como o operationId

Se você quiser utilizar o nome das funções da sua API como `operationId`s, você pode iterar sobre todos esses nomes e sobrescrever o `operationId` em  cada *operação de rota* utilizando o `APIRoute.name` dela.

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float
    is_offer: Union[bool, None] = None


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}


@app.put("/items/{item_id}")
def update_item(item_id: int, item: Item):

Наприклад, ця модель вище оголошує JSON "`об'єкт`" (або Python `dict`), як:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...оскільки `description` і `tax` є необов'язковими (зі значенням за замовчуванням `None`), цей JSON "`об'єкт`" також буде дійсним:

```JSON

* Если аннотация типа параметра представляет собой **модель Pydantic**, он будет интерпретирован как параметр **тела запроса**.

/// note | Заметка

FastAPI понимает, что значение параметра `q` не является обязательным, потому что имеет значение по умолчанию `= None`.

Аннотация `Optional` в `Optional[str]` не используется FastAPI, но помогает вашему редактору лучше понимать ваш код и обнаруживать ошибки.

In both cases this means that `item` could be an `int` or a `str`.

#### Possibly `None` { #possibly-none }

You can declare that a value could have a type, like `str`, but that it could also be `None`.

In Python 3.6 and above (including Python 3.10) you can declare it by importing and using `Optional` from the `typing` module.
