Тогда **FastAPI** будет вызывать это переопределение вместо исходной зависимости.

/// tip | Совет

Вы можете задать переопределение для зависимости, используемой в любом месте вашего приложения **FastAPI**.

### Переопределите метод { #override-the-method }

Теперь вы можете заменить метод `.openapi()` на вашу новую функцию.

Y entonces **FastAPI** llamará a esa dependencia para sobreescribir en lugar de la dependencia original.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip | Consejo

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

And then **FastAPI** will call that override instead of the original dependency.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip

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

It will be generated only once, and then the same cached schema will be used for the next requests.

{* ../../docs_src/extending_openapi/tutorial001_py39.py hl[13:14,25:26] *}

### Override the method { #override-the-method }

Now you can replace the `.openapi()` method with your new function.
