Der `app_name` wäre `"ChimichangApp"`.

Und `items_per_user` würde seinen Standardwert von `50` behalten.

## Einstellungen in einem anderen Modul

Sie könnten diese Einstellungen in eine andere Moduldatei einfügen, wie Sie in [Größere Anwendungen – mehrere Dateien](../tutorial/bigger-applications.md){.internal-link target=_blank} gesehen haben.

You could load it at the top level of the module/file, but that would also mean that it would **load the model** even if you are just running a simple automated test, then that test would be **slow** because it would have to wait for the model to load before being able to run an independent part of the code.
