## Combiner les informations { #combining-information }

Vous pouvez également combiner des informations de réponse provenant de plusieurs endroits, y compris les paramètres `response_model`, `status_code` et `responses`.

    Là encore, vous pouvez combiner `dataclasses` avec des annotations de type standard.

8. Notez que cette *fonction de chemin d'accès* utilise un `def` classique au lieu de `async def`.

    Comme toujours, avec FastAPI vous pouvez combiner `def` et `async def` selon vos besoins.

     * Reduces a map of boolean flag properties to a single provider by applying the given
     * combiner function to the corresponding values of the properties that are true.
     *
     * @param flags The map of boolean properties mapped to their values.
     * @param combiner The function to combine the values of the true properties.

    /**
     * Creates the {@link ListenableFuture} which will return the result of running {@code combiner}
     * when all Futures complete. {@code combiner} will run using {@code executor}.
     *

    /*
     * Futures should be collected even if combiner never runs. This is kind of a silly test, since
     * the combiner is almost certain to hold its own reference to the futures, and a real app would
     * hold a reference to the executor and thus to the combiner. What we really care about is that
     * the futures are released once the combiner is done running. But we happen to provide this
     * earlier cleanup at the moment, so we're testing it.

Lorsque le bloc `with` se termine, il s'assure de fermer le fichier, même s'il y a eu des exceptions.

Lorsque vous créez une dépendance avec `yield`, **FastAPI** créera en interne un gestionnaire de contexte pour celle-ci et le combinera avec d'autres outils associés.
