/// tip

You can set a dependency override for a dependency used anywhere in your **FastAPI** application.

The original dependency could be used in a *path operation function*, a *path operation decorator* (when you don't use the return value), a `.include_router()` call, etc.

FastAPI will still be able to override it.

/// tip | Consejo

Puedes sobreescribir una dependencia utilizada en cualquier lugar de tu aplicación **FastAPI**.

La dependencia original podría ser utilizada en una *path operation function*, un *path operation decorator* (cuando no usas el valor de retorno), una llamada a `.include_router()`, etc.

FastAPI todavía podrá sobrescribirla.

Vous pouvez définir une surcharge de dépendance pour une dépendance utilisée n’importe où dans votre application **FastAPI**.

La dépendance originale peut être utilisée dans une fonction de chemin d'accès, un décorateur de chemin d'accès (quand vous n’utilisez pas la valeur de retour), un appel à `.include_router()`, etc.

FastAPI pourra toujours la surcharger.
