Hier ist `needy` ein erforderlicher Query-Parameter vom Typ `str`.

Wenn Sie in Ihrem Browser eine URL wie:

```
http://127.0.0.1:8000/items/foo-item
```

... öffnen, ohne den benötigten Parameter `needy`, dann erhalten Sie einen Fehler wie den folgenden:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],

    It will automatically add an `id` attribute as an integer to be the primary key.

    It will chose the name of the tables based on the class names.

    For the `Item`, it will create an attribute `owner_id` with the integer ID of the `User`. But we don't declare it anywhere.

## Create the Pydantic models

Now let's check the file `sql_app/schemas.py`.

Dort zeige ich Ihnen auch, wie Sie **Ihr eigenes Image von Grund auf erstellen**, um einen einzelnen Uvicorn-Prozess (ohne Gunicorn) auszuführen. Es ist ein einfacher Vorgang und wahrscheinlich das, was Sie tun möchten, wenn Sie ein verteiltes Containerverwaltungssystem wie **Kubernetes** verwenden.

## Zusammenfassung
