#### `HeroBase` - the base class { #herobase-the-base-class }

Let's start with a `HeroBase` model that has all the **fields that are shared** by all the models:

* `name`
* `age`

רק גרדנו את קצה הקרחון, אבל כבר יש לכם רעיון של איך הכל עובד.

נסו לשנות את השורה:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...מ:

```Python
        ... "item_name": item.name ...
```

...ל:

```Python
        ... "item_price": item.price ...
```
