Many packages that simplify it a lot have to make many compromises with the data model, database, and available features. And some of these packages that simplify things too much actually have security flaws underneath.

**FastAPI** doesn't make any compromise with any database, data model or tool.

It gives you all the flexibility to choose the ones that fit your project the best.

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[9] *}

In diesem Fall wird **FastAPI** `__init__` nie berühren oder sich darum kümmern, wir werden es direkt in unserem Code verwenden.

## Eine Instanz erstellen

Wir könnten eine Instanz dieser Klasse erstellen mit:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

    "tax": 3.2
}
```

## Zusammenfassung

Sie können mehrere Body-Parameter zu ihrer *Pfadoperation-Funktion* hinzufügen, obwohl ein Request nur einen einzigen Body enthalten kann.

**FastAPI** wird sich darum kümmern, Ihnen korrekte Daten in Ihrer Funktion zu überreichen, und das korrekte Schema in der *Pfadoperation* zu validieren und zu dokumentieren.
