Böylece dependency'mizi "parametreleştirmiş" oluruz; artık içinde `"bar"` vardır ve bu değer `checker.fixed_content` attribute'u olarak durur.

## Instance'ı dependency olarak kullanma { #use-the-instance-as-a-dependency }

Sonra `Depends(FixedContentQueryChecker)` yerine `Depends(checker)` içinde bu `checker`'ı kullanabiliriz. Çünkü dependency, class'ın kendisi değil, `checker` instance'ıdır.

Четырёхсотые статус-коды означают, что ошибка произошла по вине клиента.

Помните ли ошибки **"404 Not Found "** (и шутки) ?

## Использование `HTTPException` { #use-httpexception }

Для возврата клиенту HTTP-ответов с ошибками используется `HTTPException`.

### Импортируйте `HTTPException` { #import-httpexception }

{* ../../docs_src/handling_errors/tutorial001_py310.py hl[1] *}

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[18] *}

Так мы «параметризуем» нашу зависимость: теперь внутри неё хранится "bar" в атрибуте `checker.fixed_content`.

## Используем экземпляр как зависимость { #use-the-instance-as-a-dependency }

Затем мы можем использовать этот `checker` в `Depends(checker)` вместо `Depends(FixedContentQueryChecker)`, потому что зависимостью является экземпляр `checker`, а не сам класс.
