Das ist dank **Pydantic** ebenfalls möglich, da es <a href="https://pydantic-docs.helpmanual.io/usage/dataclasses/#use-of-stdlib-dataclasses-with-basemodel" class="external-link" target="_blank">`dataclasses` intern unterstützt</a>.

        ArrayList<ProducedArtifact> result = new ArrayList<>(2);
        result.add(session.getArtifact(ProducedArtifact.class, pomArtifact));
        if (!ArtifactIdUtils.equalsVersionlessId(pomArtifact, projectArtifact)) {
            result.add(session.getArtifact(ProducedArtifact.class, projectArtifact));
        }
        return Collections.unmodifiableList(result);
    }

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

This is still supported thanks to **Pydantic**, as it has <a href="https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel" class="external-link" target="_blank">internal support for `dataclasses`</a>.

But you are not restricted to using some specific data model, class or type.

Do you want to have an `id` and `email` and not have any `username` in your model? Sure. You can use these same tools.

Do you want to just have a `str`? Or just a `dict`? Or a database class model instance directly? It all works the same way.
