## Create models

Create Pydantic models for:

* Notes to be created (`NoteIn`).
* Notes to be returned (`Note`).

```Python hl_lines="31-33  36-39"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

By creating these Pydantic models, the input data will be validated, serialized (converted), and annotated (documented).

# Eine Response direkt zurückgeben

Wenn Sie eine **FastAPI** *Pfadoperation* erstellen, können Sie normalerweise beliebige Daten davon zurückgeben: ein `dict`, eine `list`e, ein Pydantic-Modell, ein Datenbankmodell, usw.

Standardmäßig konvertiert **FastAPI** diesen Rückgabewert automatisch nach JSON, mithilfe des `jsonable_encoder`, der in [JSON-kompatibler Encoder](../tutorial/encoder.md){.internal-link target=_blank} erläutert wird.

    def "does not configure build when action does not query any models"() {
        setupBuild()

        when:
        def model = withConnection {
            def executer = action(new NoOpAction())
            collectOutputs(executer)
            executer.run()
        }

        then:
        model == "result"

        and:
        assertHasConfigureSuccessfulLogging()

!!! info
    Beachten Sie, dass der `TestClient` Daten empfängt, die nach JSON konvertiert werden können, keine Pydantic-Modelle.

Offline Mode Design

* UPDATE: 18-April-2005

  We cannot take the approach outlined below of detecting which remote
  repositories are "really" offline, since offline mode is more of a behavior,
  and this will lead to counter-intuitive results. A different feature may exist
