Ich habe eine Simple_form mit einer gruppierten Sammlung auswählen und zwei Eingabefelder. Ich habe eine Pflicht: wahr auf beiden Feldern, aber es erlaubt immer noch leere Eingabe durch. Das kleine "erforderliche" Sternchen erscheint neben dem Feldnamen, aber das war's. Kann ich irgendwie verhindern, dass leere Eingaben das Formular durchlaufen?Schienen 'erforderlich: True' funktioniert nicht vollständig
