And the `items_per_user` would keep its default value of `50`.

## Settings in another module

You could put those settings in another module file as you saw in [Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}.

For example, you could have a file `config.py` with:

```Python
{!../../../docs_src/settings/app01/config.py!}
```

然后，`admin_email` 设置将为 `"******@****.***"`。

`app_name` 将为 `"ChimichangApp"`。

而 `items_per_user` 将保持其默认值为 `50`。

## 在另一个模块中设置

您可以将这些设置放在另一个模块文件中，就像您在[Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}中所见的那样。

例如，您可以创建一个名为 `config.py` 的文件，其中包含以下内容：

```Python
{!../../../docs_src/settings/app01/config.py!}
```

## 使用 CLI 登录

现在，使用 CLI 登录 Deta：

<div class="termy">

```console
$ deta login

Please, log in from the web page. Waiting..
Logged in successfully.
```

</div>

这个命令会打开浏览器并自动验证身份。

## 使用 Deta 部署

接下来，使用 Deta CLI 部署应用：

<div class="termy">

```console
$ deta new

!!! warning
    The recommended way to handle the *startup* and *shutdown* is using the `lifespan` parameter of the `FastAPI` app as described above. If you provide a `lifespan` parameter, `startup` and `shutdown` event handlers will no longer be called. It's all `lifespan` or all events, not both.

    You can probably skip this part.

There's an alternative way to define this logic to be executed during *startup* and during *shutdown*.
