## Use the model

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

//// tab | Python 3.10+

```Python hl_lines="19"
{!> ../../docs_src/body/tutorial002_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="21"
{!> ../../docs_src/body/tutorial002.py!}
```

////

## Request body + path parameters

//// tab | Python 3.10+

```Python hl_lines="11  13  20  23"

//// tab | Python 3.8+

```Python hl_lines="13  15  22  25"
{!> ../../docs_src/background_tasks/tutorial002.py!}
```

////

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

//// tab | Python 3.10+

```Python hl_lines="7"
{!> ../../docs_src/query_params/tutorial002_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="9"

/// info

Support for `separate_input_output_schemas` was added in FastAPI `0.102.0`. 🤓

{* ../../docs_src/separate_openapi_schemas/tutorial002_py310.py hl[10] *}

### 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**:

```Python hl_lines="4  10-13"
{!> ../../docs_src/schema_extra_example/tutorial002.py!}
```

////

//// tab | 🐍 3️⃣.1️⃣0️⃣ & 🔛

    "tax": 3.2
}
```

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

//// tab | Python 3.10+

```Python hl_lines="20"
{!> ../../docs_src/body_multiple_params/tutorial002_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="22"
{!> ../../docs_src/body_multiple_params/tutorial002.py!}
```

////

//// tab | Python 3.8 і вище

```Python hl_lines="21"
{!> ../../docs_src/body/tutorial002.py!}
```

////

//// tab | Python 3.10 і вище

```Python hl_lines="19"
{!> ../../docs_src/body/tutorial002_py310.py!}
```

////

## 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 :

//// tab | Python 3.10+

```Python hl_lines="20"
{!> ../../docs_src/body_multiple_params/tutorial002_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="22"
{!> ../../docs_src/body_multiple_params/tutorial002.py!}
```
