And by doing so, **FastAPI** is validating that data, converting it and generating documentation for your API automatically.

But there are situations where you might need to access the `Request` object directly.

## Details about the `Request` object

	"github.com/minio/minio/internal/logger"
	"github.com/minio/pkg/v3/quick"
)

// FileLogger is introduced to workaround the dependency about logrus
type FileLogger struct {
	Enable   bool   `json:"enable"`
	Filename string `json:"filename"`
}

// ConsoleLogger is introduced to workaround the dependency about logrus
type ConsoleLogger struct {
	Enable bool `json:"enable"`
}

       gives data about available versions (<<<latest>>>, <<<release>>>, <<<versions>>> list and <<<lastUpdated>>>),

 [[3]] in a "groupId/artifactId/version" snapshot artifact directory: metadata describes <<<groupId>>>, <<<artifactId>>>, <<<version>>> (base version, i.e. ending in <<<-SNAPSHOT>>>) and

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[9] *}

In this case, **FastAPI** won't ever touch or care about `__init__`, we will use it directly in our code.

## Create an instance

We could create an instance of this class with:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

8. Notice that this *path operation function* uses regular `def` instead of `async def`.

    As always, in FastAPI you can combine `def` and `async def` as needed.

    If you need a refresher about when to use which, check out the section _"In a hurry?"_ in the docs about [`async` and `await`](../async.md#in-a-hurry){.internal-link target=_blank}.

And the sub-application could also have its own mounted sub-applications and everything would work correctly, because FastAPI handles all these `root_path`s automatically.

You probably have seen how to declare the `response_model` and `status_code` for a *path operation*.

That defines the metadata about the main response of a *path operation*.

You can also declare additional responses with their models, status codes, etc.

There's a whole chapter here in the documentation about it, you can read it at [Additional Responses in OpenAPI](additional-responses.md){.internal-link target=_blank}.
