### `response_model` Priority

If you declare both a return type and a `response_model`, the `response_model` will take priority and be used by FastAPI.

### Приоритет `response_model`

Если одновременно указать аннотацию типа для ответа функции и параметр `response_model` - последний будет иметь больший приоритет и FastAPI будет использовать именно его.

    Beachten Sie, dass `response_model` ein Parameter der „Dekorator“-Methode ist (`get`, `post`, usw.). Nicht der *Pfadoperation-Funktion*, so wie die anderen Parameter.

#### Получение *значения перечисления*

Можно получить фактическое значение (в данном случае - `str`) с помощью `model_name.value` или в общем случае `your_enum_member.value`:

#### Récupérer la *valeur de l'énumération*

Vous pouvez obtenir la valeur réel d'un membre (une chaîne de caractères ici), avec `model_name.value`, ou en général, `votre_membre_d'enum.value` :
