#### `HeroCreate` - the *data model* to create a hero { #herocreate-the-data-model-to-create-a-hero }

Now we create a `HeroCreate` model, this is the one that will **validate** the data from the clients.

It has the same fields as `HeroBase`, and it also has `secret_name`.

Now, when the clients **create a new hero**, they will send the `secret_name`, it will be stored in the database, but those secret names won't be returned in the API to the clients.
