By validating the data with Pydantic we can make sure that we have, for example, exactly a `list` of `str` with the scopes and a `str` with the `username`.

Instead of, for example, a `dict`, or something else, as it could break the application at some point later, making it a security risk.

We also verify that we have a user with that username, and if not, we raise that same exception we created before.

This will easily let you test that your app with Peewee and FastAPI is behaving correctly with all the stuff about threads.

If you want to check how Peewee would break your app if used without modification, go the `sql_app/database.py` file and comment the line:

```Python
# db._state = PeeweeConnectionState()
```

### Nowoczesny Python

Wszystko opiera się na standardowych deklaracjach typu **Python 3.8** (dzięki Pydantic). Brak nowej składni do uczenia. Po prostu standardowy, współczesny Python.
