and when not to use hyphens in words (written in first person, which is you)

In der Regel versuche ich so weit wie möglich Worte zusammenzuschreiben, also ohne Bindestrich, es sei denn, es ist Konkretesding-Klassevondingen, etwa «Pydantic-Modell» (aber: «Datenbankmodell»), «Python-Modul» (aber: «Standardmodul»). Ich setze auch einen Bindestrich, wenn er die gleichen Buchstaben verbindet, etwa «Enum-Member», «Cloud-Dienst», «Template-Engine». Oder wenn das Wort sonst einfach zu lang wird,...

Muitos pacotes que simplificam bastante isso precisam fazer muitas concessões com o modelo de dados, o banco de dados e os recursos disponíveis. E alguns desses pacotes que simplificam demais na verdade têm falhas de segurança subjacentes.

O **FastAPI** não faz nenhuma concessão com nenhum banco de dados, modelo de dados ou ferramenta.

Import `BaseSettings` from Pydantic and create a sub-class, very much like with a Pydantic model.

The same way as with Pydantic models, you declare class attributes with type annotations, and possibly default values.

You can use all the same validation features and tools you use for Pydantic models, like different data types and additional validations with `Field()`.

/**

 * overriding going on amongst the models being used in this test:
 * each model in the lineage is providing a value that is not present
 * anywhere else in the lineage. We are just making sure that values

/// warning | Achtung

Wenn Sie eine `Response` direkt zurückgeben, wie im obigen Beispiel, wird sie direkt zurückgegeben.

Sie wird nicht mit einem Modell usw. serialisiert.

Stellen Sie sicher, dass sie die gewünschten Daten enthält und dass die Werte gültiges JSON sind (wenn Sie `JSONResponse` verwenden).

Y luego puedes devolver cualquier objeto que necesites, como harías normalmente (un `dict`, un modelo de base de datos, etc).

Y si declaraste un `response_model`, aún se usará para filtrar y convertir el objeto que devolviste.
