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. 🪄

Then we use `hero_db.sqlmodel_update(hero_data)` to update the `hero_db` with the data from `hero_data`.
