从`database`（来自上面的`database.py`文件）导入`Base`。

创建从它继承的类。

这些类就是 SQLAlchemy 模型。

```Python hl_lines="4  7-8  18-19"
{!../../../docs_src/sql_databases/sql_app/models.py!}
```

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）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。

Create classes that inherit from it.

These classes are the SQLAlchemy models.

```Python hl_lines="4  7-8  18-19"
{!../../../docs_src/sql_databases/sql_app/models.py!}
```

The `__tablename__` attribute tells SQLAlchemy the name of the table to use in the database for each of these models.

### Create model attributes/columns

Now create all the model (class) attributes.

🗄 `Base` ⚪️➡️ `database` (📁 `database.py` ⚪️➡️ 🔛).
