Capacity constrained environments, MinIO will work but not recommended for production.

- FieldManager no longer owns fields that get reset before the object is persisted (e.g. "status wiping"). ([#99661](https://github.com/kubernetes/kubernetes/pull/99661), [@kevindelgado](https://github.com/kevindelgado)) [SIG API Machinery, Auth and Testing]

# Get Current User { #get-current-user }

In the previous chapter the security system (which is based on the dependency injection system) was giving the *path operation function* a `token` as a `str`:

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

But that is still not that useful.

Let's make it give us the current user.

## Create a user model { #create-a-user-model }

First, let's create a Pydantic user model.

## Before filing an issue

If you are unsure whether you have found a bug, please consider asking in the [golang-nuts mailing
list](https://groups.google.com/forum/#!forum/golang-nuts) or [other forums](https://golang.org/help/) first. If
the behavior you are seeing is confirmed as a bug or issue, it can easily be re-raised in the issue tracker.
