## Налаштування як залежність { #settings-in-a-dependency }

Іноді може бути корисно надавати налаштування через залежність, замість того, щоб мати глобальний об'єкт `settings`, який використовується всюди.

    * The cache can be disabled per dependency declaration, using `use_cache=False` as in `Depends(your_dependency, use_cache=False)`.
    * Updated docs at: [Using the same dependency multiple times](https://fastapi.tiangolo.com/tutorial/dependencies/sub-dependencies/#using-the-same-dependency-multiple-times).
    * PR [#292](https://github.com/tiangolo/fastapi/pull/292).

# Config to use a mostly-static build and disable modular op registration
# support (this will revert to loading TensorFlow with RTLD_GLOBAL in Python).
# By default, TensorFlow will build with a dependence on
# //tensorflow:libtensorflow_framework.so.

                        // Only VM sub-projects that are specifically opted-in to testing Docker should
                        // have the Docker task added as a dependency. Although we control whether Docker
                        // is installed in the VM via `Vagrantfile` and we could auto-detect its presence

Und auf diese Weise können wir unsere Abhängigkeit „parametrisieren“, die jetzt `"bar"` enthält, als das Attribut `checker.fixed_content`.

## Die Instanz als Abhängigkeit verwenden { #use-the-instance-as-a-dependency }

Dann könnten wir diesen `checker` in einem `Depends(checker)` anstelle von `Depends(FixedContentQueryChecker)` verwenden, da die Abhängigkeit die Instanz `checker` und nicht die Klasse selbst ist.

Tudo construído como ferramentas e componentes reutilizáveis que são fáceis de integrar com seus sistemas, armazenamento de dados, banco de dados relacionais e não-relacionais etc.

FastAPI inclui um sistema de <dfn title='também conhecido como "componentes", "recursos", "serviços", "provedores"'><strong>injeção de dependência</strong></dfn> extremamente fácil de usar, mas extremamente poderoso.
