你还可以创建一个 [自定义异常处理器](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank} 用于捕获异常（同时也可以抛出另一个 `HTTPException`）。

## 包含 `yield` 和 `except` 的依赖项

如果你在包含 `yield` 的依赖项中使用 `except` 捕获了一个异常，然后你没有重新抛出该异常（或抛出一个新异常），与在普通的Python代码中相同，FastAPI不会注意到发生了异常。

## Install `SQLModel`

First, make sure you create your [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

## Create the App with a Single Model
