### Используйте атрибут `app.dependency_overrides` { #use-the-app-dependency-overrides-attribute }

Для таких случаев у вашего приложения **FastAPI** есть атрибут `app.dependency_overrides`, это простой `dict`.

Bevor wir tiefer in das **Dependency Injection** System eintauchen, lassen Sie uns das vorherige Beispiel verbessern.

## Ein `dict` aus dem vorherigen Beispiel { #a-dict-from-the-previous-example }

### Dependency Injection { #dependency-injection }

FastAPI enthält ein extrem einfach zu verwendendes, aber extrem mächtiges <abbr title='auch bekannt als „Komponenten“, „Resourcen“, „Dienste“, „Dienstanbieter“'><strong>Dependency Injection</strong></abbr> System.

### Dependency Injection { #dependency-injection }

FastAPI includes an extremely easy to use, but extremely powerful <abbr title='also known as "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> system.
