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`.

Aber nun wissen Sie, dass Sie sie in **FastAPI** immer dann verwenden können, wenn Sie sie brauchen.

## Defaultwerte { #default-values }

Natürlich können Sie Defaultwerte verwenden, die nicht `None` sind.

Nehmen wir an, Sie möchten, dass der `q` Query-Parameter eine `min_length` von `3` hat und einen Defaultwert von `"fixedquery"`:

Mas saiba que isso está descontinuado e deve ser atualizado para usar o novo parâmetro `pattern`. 🤓

## Valores padrão { #default-values }

Você pode, claro, usar valores padrão diferentes de `None`.

Digamos que você queira declarar o parâmetro de consulta `q` com `min_length` de `3` e ter um valor padrão de `"fixedquery"`:
