### Declare a *path parameter* { #declare-a-path-parameter }

Then create a *path parameter* with a type annotation using the enum class you created (`ModelName`):

        Item(name="baz", date=datetime(2021, 7, 26), price=2.0, owner_ids=[1, 2, 3]),
    ]


@app.get("/items/no-response-model/object")

        name="object", date=datetime(2021, 7, 26), price=1.0, owner_ids=[1, 2, 3]
    )


@app.get("/items/no-response-model/objectlist")
def get_no_response_model_objectlist():
    return [
        Item(name="foo", date=datetime(2021, 7, 26)),
