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!}
```

  // that may be executing at a time --- for each such priority
  // level:
  //
  //             ACV(l) = ceil( SCL * ACS(l) / ( sum[priority levels k] ACS(k) ) )
  //
  // bigger numbers of ACS mean more reserved concurrent requests (at the
  // expense of every other PL).
  // This field has a default value of 30.
  // +optional
  optional int32 assuredConcurrencyShares = 1;

  // that may be executing at a time --- for each such priority
  // level:
  //
  //             ACV(l) = ceil( SCL * ACS(l) / ( sum[priority levels k] ACS(k) ) )
  //
  // bigger numbers of ACS mean more reserved concurrent requests (at the
  // expense of every other PL).
  // This field has a default value of 30.
  // +optional
  optional int32 assuredConcurrencyShares = 1;

The client will get a **500 Internal Server Error** for that request, but the application will continue working for the next requests instead of just crashing completely.

### Bigger Errors - Crashes

Nevertheless, there might be cases where we write some code that **crashes the entire application** making Uvicorn and Python crash. 💥

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!}
```

  // that may be executing at a time --- for each such priority
  // level:
  //
  //             ACV(l) = ceil( SCL * ACS(l) / ( sum[priority levels k] ACS(k) ) )
  //
  // bigger numbers of ACS mean more reserved concurrent requests (at the
  // expense of every other PL).
  // This field has a default value of 30.
  // +optional
  optional int32 assuredConcurrencyShares = 1;

  // Limited priority levels in proportion to their NCS values:
  //
  // NominalCL(i)  = ceil( ServerCL * NCS(i) / sum_ncs )
  // sum_ncs = sum[limited priority level k] NCS(k)
  //
  // Bigger numbers mean a larger nominal concurrency limit,
  // at the expense of every other Limited priority level.
  // This field has a default value of 30.
  // +optional
  optional int32 nominalConcurrencyShares = 1;

    * <a href="https://fastapi.tiangolo.com/tutorial/bigger-applications/" class="external-link" target="_blank">Tutorial - Bigger Applications</a>.

  // mounted only with a single SELinux context.
  //
  // When "false", Kubernetes won't pass any special SELinux mount options to the driver.
  // This is typical for volumes that represent subdirectories of a bigger shared filesystem.
  //
  // Default is "false".
  //
  // +featureGate=SELinuxMountReadWriteOncePod
  // +optional
  optional bool seLinuxMount = 8;
}

The response object will also have autocompletion:

## FastAPI App with Tags

In many cases your FastAPI app will be bigger, and you will probably use tags to separate different groups of *path operations*.

For example, you could have a section for **items** and another section for **users**, and they could be separated by tags:
