Eğer tarayıcınızda <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a> sayfasını açarsanız, şuna benzer güzel bir HTTP hatası ile karşılaşırsınız:

      "loc": [
        "path",
        "item_id"
      ],

## Зависимости для групп *операций пути* { #dependencies-for-groups-of-path-operations }

And the `items_per_user` would keep its default value of `50`.

## Settings in another module { #settings-in-another-module }

You could put those settings in another module file as you saw in [Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}.

For example, you could have a file `config.py` with:

{* ../../docs_src/settings/app01_py39/config.py *}

## Dependências para conjuntos de *operações de rota* { #dependencies-for-groups-of-path-operations }

## Abhängigkeiten für Gruppen von *Pfadoperationen* { #dependencies-for-groups-of-path-operations }
