But remember that when you import `Query`, `Path`, `File` and others from `fastapi`, those are actually functions that return special classes.

!!! tip
    To declare File bodies, you need to use `File`, because otherwise the parameters would be interpreted as query parameters or body (JSON) parameters.

The files will be uploaded as "form data".

		exist if its backing file path is empty. Support for the -overlay flag
		has some limitations: importantly, cgo files included from outside the
		include path must be in the same directory as the Go package they are
		included from, and overlays will not appear when binaries and tests are
		run through go run and go test respectively.

By creating a function that is only dedicated to getting your user from a `username` (or any other parameter) independent of your *path operation function*, you can more easily reuse it in multiple parts and also add <abbr title="Automated test, written in code, that checks if another piece of code is working correctly.">unit tests</abbr> for it:
