## Details { #details }

The first `"/static"` refers to the sub-path this "sub-application" will be "mounted" on. So, any path that starts with `"/static"` will be handled by it.

## Detalles { #details }

El primer `"/static"` se refiere al sub-path en el que esta "sub-aplicación" será "montada". Por lo tanto, cualquier path que comience con `"/static"` será manejado por ella.

# Geschichte, Design und Zukunft { #history-design-and-future }

Vor einiger Zeit fragte <a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">ein **FastAPI**-Benutzer</a>:

> Was ist die Geschichte dieses Projekts? Es scheint aus dem Nichts in ein paar Wochen zu etwas Großartigem geworden zu sein [...]

Hier ist ein wenig über diese Geschichte.

## Alternativen { #alternatives }

Die vorherigen Screenshots wurden mit <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a> aufgenommen.

Aber Sie würden die gleiche Editor-Unterstützung in <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> und den meisten anderen Python-Editoren erhalten:

Um hochgeladene Dateien zu empfangen, installieren Sie zuerst <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und dann das Paket installieren, zum Beispiel:

```console
$ pip install python-multipart
```

虽然上面的截图取自 <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>。

但 <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> 和大多数 Python 编辑器也支持同样的功能：

# Advanced User Guide { #advanced-user-guide }

## Additional Features { #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"**.

So, a `datetime` object would have to be converted to a `str` containing the data in <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO format</a>.

The same way, this database wouldn't receive a Pydantic model (an object with attributes), only a `dict`.

You can use `jsonable_encoder` for that.
