Validations specific for strings:

* `min_length`
* `max_length`
* `pattern`

Custom validations using `AfterValidator`.

In these examples you saw how to declare validations for `str` values.

#### `HeroPublic` - the public *data model* { #heropublic-the-public-data-model }

Next, we create a `HeroPublic` model, this is the one that will be **returned** to the clients of the API.

It has the same fields as `HeroBase`, so it won't include `secret_name`.
