Bei einigen Anwendungstypen möchten Sie möglicherweise Abhängigkeiten zur gesamten Anwendung hinzufügen.

Ähnlich wie Sie [`dependencies` zu den *Pfadoperation-Dekoratoren* hinzufügen](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} können, können Sie sie auch zur `FastAPI`-Anwendung hinzufügen.

In diesem Fall werden sie auf alle *Pfadoperationen* in der Anwendung angewendet:

            Currency.PESO, Country.CHILE,
            Currency.FRANC, Country.SWITZERLAND);
    EnumBiMap<Currency, Country> bimap = EnumBiMap.create(map);

    Iterator<Currency> iter = bimap.keySet().iterator();
    assertEquals(Currency.DOLLAR, iter.next());
    iter.remove();

    // forward map ordered by currency
    assertThat(bimap.keySet()).containsExactly(Currency.FRANC, Currency.PESO).inOrder();

max_sleep      (duration)  maximum sleep duration between objects to slow down heal operation. eg. 2s
max_io         (int)       maximum IO requests allowed between objects to slow down heal operation. eg. 3
drive_workers  (int)       the number of workers per drive to heal a new disk replacement.

* operation IDs: IDs de operação
* path (as in URL path): path
* path operation: operação de rota
* path operation function: função de operação de rota
* prefix: prefixo
* request (as in HTTP request): request (do not change if it's already translated to requisição)

Puedes configurar el parámetro del decorador de path operation `response_model_exclude_unset=True`:

{* ../../docs_src/response_model/tutorial004_py310.py hl[22] *}

y esos valores por defecto no serán incluidos en el response, solo los valores realmente establecidos.

Entonces, si envías un request a esa *path operation* para el ítem con ID `foo`, el response (no incluyendo valores por defecto) será:

If you have quite some technical knowledge (coroutines, threads, blocking, etc.) and are curious about how FastAPI handles `async def` vs normal `def`, go ahead.

///

### Path operation functions { #path-operation-functions }

When you declare a *path operation function* with normal `def` instead of `async def`, it is run in an external threadpool that is then awaited, instead of being called directly (as it would block the server).
