## Без Pydantic

## Создание вашей собственной модели

После этого вы описываете вашу модель данных как класс, наследующий от `BaseModel`.

Используйте аннотации типов Python для всех атрибутов:

```Python hl_lines="7-11"
{!../../../docs_src/body/tutorial001.py!}
```

=== "Python 3.10+"

    ```Python hl_lines="12"
    {!> ../../../docs_src/body_nested_models/tutorial002_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="14"
    {!> ../../../docs_src/body_nested_models/tutorial002_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="14"
    {!> ../../../docs_src/body_nested_models/tutorial002.py!}
    ```

## Типы множеств

    {!> ../../../docs_src/body_nested_models/tutorial006_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="20"

    ```

=== "Python 3.8+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial006.py!}
    ```

=== "Python 3.10+"

    ```Python hl_lines="18-20"
    {!> ../../../docs_src/body_multiple_params/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="18-20"

    ```Python hl_lines="19-21"

   * Invoked immediately after receiving a response body and completing reading it.
   *
   * Will only be invoked for requests having a response body e.g. won't be invoked for a web socket
   * upgrade.

    val responseBodySink =
      sink.withThrottlingAndSocketPolicy(
        policy = response,
        disconnectHalfway = response.socketPolicy == DisconnectDuringResponseBody,
        expectedByteCount = body.contentLength,

    body.writeTo(responseBodySink)

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

вы также можете добавить аргумент, содержащий `example` или группу `examples` с дополнительной информацией, которая будет добавлена в **OpenAPI**.

### Параметр `Body` с аргументом `example`

Здесь мы передаём аргумент `example`, как пример данных ожидаемых в параметре `Body()`:
