```JSON

    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",

## Verwendung von `Jinja2Templates`

* Importieren Sie `Jinja2Templates`.
* Erstellen Sie ein `templates`-Objekt, das Sie später wiederverwenden können.
* Deklarieren Sie einen `Request`-Parameter in der *Pfadoperation*, welcher ein Template zurückgibt.

In diesem Fall können Sie diese Funktion in **FastAPI** mit dem Parameter `separate_input_output_schemas=False` deaktivieren.

+ Make commits of logical units.
+ Respect the original code style: by using the same [codestyle][code-style],
  patches should only highlight the actual difference, not being disturbed by any formatting issues:
  + Only use spaces for indentation.
  + Create minimal diffs - disable on save actions like reformat source code or organize imports.
    If you feel the source code should be reformatted, create a separate PR for this change.

**FastAPI** bietet dieselben `starlette.status`-Codes auch via `fastapi.status` an, als Annehmlichkeit für Sie, den Entwickler. Sie kommen aber direkt von Starlette.
