#### `Hero` - *表模型* { #hero-the-table-model }

接下来，我们创建 `Hero`，实际的*表模型*，并添加那些不总是在其他模型中的**额外字段**：

* `id`
* `secret_name`

因为 `Hero` 继承自 `HeroBase`，所以它**也**包含了在 `HeroBase` 中声明过的**字段**。因此 `Hero` 的所有字段为：

* `id`
* `name`
* `age`
* `secret_name`

Sie sollten also in der Lage sein, eine Version wie folgt anzupinnen:

SQLModel을 사용하면 **상속**을 통해 모든 경우에 필드를 **중복 선언하지 않아도** 됩니다.

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

모든 모델에서 **공유되는 필드**를 가진 `HeroBase` 모델을 시작해 봅시다:

* `name`
* `age`

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

#### `Hero` - *테이블 모델* { #hero-the-table-model }

다음으로 실제 *테이블 모델*인 `Hero`를 생성합니다. 이 모델은 다른 모델에는 항상 포함되는 건 아닌 **추가 필드**를 포함합니다:
