### Update a Hero with `HeroUpdate` { #update-a-hero-with-heroupdate }

We can **update a hero**. For this we use an HTTP `PATCH` operation.

And in the code, we get a `dict` with all the data sent by the client, **only the data sent by the client**, excluding any values that would be there just for being the default values. To do it we use `exclude_unset=True`. This is the main trick. 🪄

### Idempotent versions on delete markers

Duplicate delete markers are not created on MinIO buckets with versioning, if an application performs a soft delete on an object repeatedly - that object will only ever have a single DELETE marker for all such successive attempts. This is done to ensure that repeated soft deletes do not ever need multiple versions in the first place.
