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!}
```

COPY ./requirements.txt /app/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /app/requirements.txt

COPY ./app /app
```

### より大きなアプリケーション

[複数のファイルを持つ大きなアプリケーション](../tutorial/bigger-applications.md){.internal-link target=_blank}を作成するセクションに従った場合、`Dockerfile`は次のようになります：

```Dockerfile hl_lines="7"
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.9

COPY ./requirements.txt /app/requirements.txt

```Python hl_lines="1  3" title="app/routers/users.py"

Кроме того, Ваше приложение **FastAPI** может состоять из нескольких файлов, модулей и т.п.

### Файл приложения **FastAPI**

Допустим, структура файлов Вашего приложения похожа на ту, что описана на странице [Более крупные приложения](bigger-applications.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

Everyone before you is waiting for their burgers to be ready before leaving the counter because each of the 8 cashiers goes and prepares the burger right away before getting the next order.

## 分离测试

在实际应用中，你可能会把你的测试放在另一个文件里。

您的**FastAPI**应用程序也可能由一些文件/模块组成等等。

### **FastAPI** app 文件

假设你有一个像 [更大的应用](bigger-applications.md){.internal-link target=_blank} 中所描述的文件结构:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

在 `main.py` 文件中你有一个 **FastAPI** app:
