这个`__tablename__`属性是用来告诉 SQLAlchemy 要在数据库中为每个模型使用的数据库表的名称。

### 创建模型属性/列

现在创建所有模型（类）的属性。

这些属性中的每一个都代表其相应数据库表中的一列。

我们使用`Column`来表示 SQLAlchemy 中的默认值。

我们传递一个 SQLAlchemy “类型”，如`Integer`、`String`和`Boolean`，它定义了数据库中的类型，作为参数。

```Python hl_lines="1  10-13  21-24"
{!../../docs_src/sql_databases/sql_app/models.py!}
```

### 创建关系

现在创建关系。

为此，我们使用SQLAlchemy  ORM提供的`relationship`。
