## Sponsoren

Dies sind die **Sponsoren**. 😎

Sie unterstützen meine Arbeit an **FastAPI** (und andere), hauptsächlich durch <a href="https://github.com/sponsors/tiangolo" class="external-link" target="_blank">GitHub-Sponsoren</a>.

### Gold Sponsoren

{% if sponsors %}

``` hl_lines="5"
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

Так как оба файла находятся в одной директории, для импорта объекта приложения из файла `main` в файл `test_main` Вы можете использовать относительный импорт:

```Python hl_lines="3"
{!../../../docs_src/app_testing/test_main.py!}
```

...и писать дальше тесты, как и раньше.

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

The file `main.py` would have:

```Python
{!../../../docs_src/async_tests/main.py!}
```

The file `test_main.py` would have the tests for `main.py`, it could look like this now:

```Python
{!../../../docs_src/async_tests/test_main.py!}
```

## Run it

You can run your tests as usual via:

```Python hl_lines="1  3  7" title="app/main.py"
{!../../../docs_src/bigger_applications/app/main.py!}
```

### Den `APIRouter` importieren

Jetzt importieren wir die anderen Submodule, die `APIRouter` haben:

```Python hl_lines="4-5" title="app/main.py"
{!../../../docs_src/bigger_applications/app/main.py!}
```

NAME                   ADDRESSES PORT  MATCH DESTINATION
listener/main_internal           0     ALL   Cluster: inbound-vip|8100|http|httpbin.default.svc.cluster.local
listener/main_internal           0     ALL   Cluster: inbound-vip|8000|http|httpbin.default.svc.cluster.local
listener/main_internal           0     ALL   Cluster: encap
listener/main_internal           0     ALL   Cluster: encap

* `main:app`: Das ist die gleiche Syntax, die auch von Uvicorn verwendet wird. `main` bedeutet das Python-Modul mit dem Namen `main`, also eine Datei `main.py`. Und `app` ist der Name der Variable, welche die **FastAPI**-Anwendung ist.
    * Stellen Sie sich einfach vor, dass `main:app` einer Python-`import`-Anweisung wie der folgenden entspricht:

        ```Python
        from main import app
        ```

# Advanced User Guide

## Additional Features

The main [Tutorial - User Guide](../tutorial/index.md){.internal-link target=_blank} should be enough to give you a tour through all the main features of **FastAPI**.

In the next sections you will see other options, configurations, and additional features.

!!! tip
    The next sections are **not necessarily "advanced"**.

    And it's possible that for your use case, the solution is in one of them.

[19515] [INFO] Application startup complete.

让我们看看每个选项的含义：

* `main:app`：这与 Uvicorn 使用的语法相同，`main` 表示名为"`main`"的 Python 模块，因此是文件 `main.py`。 `app` 是 **FastAPI** 应用程序的变量名称。
     * 你可以想象 `main:app` 相当于一个 Python `import` 语句，例如：

        ```Python
        from main import app
        ```

     * 因此，`main:app` 中的冒号相当于 `from main import app` 中的 Python `import` 部分。

## Requirements and limits

## Main **FastAPI** app

And now in the file `sql_app/main.py` let's integrate and use all the other parts we created before.

### Create the database tables

In a very simplistic way create the database tables:

```Python hl_lines="9-11"
{!../../../docs_src/sql_databases_peewee/sql_app/main.py!}
```

### Create a dependency
