And then you can set the `status_code` in that *temporal* response object.

{* ../../docs_src/response_change_status_code/tutorial001.py hl[1,9,12] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.
