If you already have a code base that uses <a href="https://docs.peewee-orm.com/en/latest/" class="external-link" target="_blank">Peewee ORM</a>, you can check here how to use it with **FastAPI**.

!!! warning "Python 3.7+ required"
    You will need Python 3.7 or above to safely use Peewee with FastAPI.

## Peewee for async

Peewee was not designed for async frameworks, or with them in mind.

它可能有一个像`"Arquilian"`(一种业务逻辑)。

当您尝试从您的宠物对象访问它时，ORM 将完成所有工作以从相应的表*所有者那里再获取信息。*

常见的 ORM 例如：Django-ORM（Django 框架的一部分）、SQLAlchemy ORM（SQLAlchemy 的一部分，独立于框架）和 Peewee（独立于框架）等。

在这里，我们将看到如何使用**SQLAlchemy ORM**。

以类似的方式，您也可以使用任何其他 ORM。

!!! tip
    在文档中也有一篇使用 Peewee 的等效的文章。

## 文件结构

对于这些示例，假设您有一个名为的目录`my_super_project`，其中包含一个名为的子目录`sql_app`，其结构如下：

```
.
└── sql_app
    ├── __init__.py
    ├── crud.py

Common ORMs are for example: Django-ORM (part of the Django framework), SQLAlchemy ORM (part of SQLAlchemy, independent of framework) and Peewee (independent of framework), among others.

Here we will see how to work with **SQLAlchemy ORM**.

In a similar way you could use any other ORM.

!!! tip
    There's an equivalent article using Peewee here in the docs.
