## Documentation Deprecate a *Path Operation* - OpenAPI { #documentation-deprecate-a-path-operation-openapi }

To deprecate a *path operation*, and show it in the docs UI, read the docs for [Tutorial - Path Operation Configurations - Deprecation](../tutorial/path-operation-configuration.md#deprecate-a-path-operation){.internal-link target=_blank}.

## Convert any Data to JSON-compatible { #convert-any-data-to-json-compatible }

```

...that's because the client generator uses the OpenAPI internal **operation ID** for each *path operation*.

OpenAPI requires that each operation ID is unique across all the *path operations*, so FastAPI uses the **function name**, the **path**, and the **HTTP method/operation** to generate that operation ID, because that way it can make sure that the operation IDs are unique.

But I'll show you how to improve that next. 🤓

## Documentar la Deprecación de una *Path Operation* - OpenAPI { #documentation-deprecate-a-path-operation-openapi }

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.
```

## To `async` or not to `async` { #to-async-or-not-to-async }

As dependencies will also be called by **FastAPI** (the same as your *path operation functions*), the same rules apply while defining your functions.

You can use `async def` or normal `def`.

And all these thousands of *path operations* can be as small as 3 lines:

{* ../../docs_src/security/tutorial002_an_py310.py hl[30:32] *}

## Recap { #recap }

You can now get the current user directly in your *path operation function*.

We are already halfway there.

We just need to add a *path operation* for the user/client to actually send the `username` and `password`.

Y todas estas miles de *path operations* pueden ser tan pequeñas como 3 líneas:

{* ../../docs_src/security/tutorial002_an_py310.py hl[30:32] *}

## Resumen { #recap }

Ahora puedes obtener el usuario actual directamente en tu *path operation function*.

Ya estamos a mitad de camino.

Solo necesitamos agregar una *path operation* para que el usuario/cliente envíe realmente el `username` y `password`.
