Аналогично, вы можете объявлять необязательные query-параметры, установив их значение по умолчанию, равное `None`:

### Same Schema for Input and Output Models in Docs

And now there will be one single schema for input and output for the model, only `Item`, and it will have `description` as **not required**:

///

## Use the model

Inside of the function, you can access all the attributes of the model object directly:

```

Но вы также можете объявить множество параметров тела запроса, например `item` и `user`:

```

////

## Тіло запиту + параметри шляху

Ви можете одночасно оголошувати параметри шляху та тіло запиту.

```

Mais vous pouvez également déclarer plusieurs paramètres provenant de body, par exemple `item` et `user` simultanément :
