#### Базовый класс `HeroBase`

Давайте начнём с модели `HeroBase`, которая содержит поля, общие для всех моделей:

* `name`
* `age`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:9] hl[7:9] *}

#### Модель таблицы `Hero`

This will skip the normal events such as DNS, connecting to the network, and downloading the response body.

As recommended by the HTTP RFC the max age of a document is defaulted to 10% of the 
document's age at the time it was served based on "Last-Modified". Default expiration dates aren't used for URIs 
containing a query.

 - **CacheHit**

### Cache Miss

#### `HeroBase` - la clase base

Comencemos con un modelo `HeroBase` que tiene todos los **campos que son compartidos** por todos los modelos:

* `name`
* `age`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:9] hl[7:9] *}

#### `Hero` - el *modelo de tabla*

Поскольку редактор знает типы переменных, вы получаете не только дополнение, но и проверки ошибок:

Теперь вы знаете, что вам нужно исправить, преобразовав `age` в строку с `str(age)`:

{* ../../docs_src/python_types/tutorial004.py hl[2] *}
