Ich habe ein Bootstrap-Modal für die Devise-Anmeldung erstellt, das über einen Link auf der Zielseiten-Navigationsleiste aufgerufen werden kann. Das Modal funktioniert ordnungsgemäß, d. H. Es wird ein Benutzer erstellt. Aber wenn ich versuche, den Kennwortlängenhinweis zur Passworteingabe hinzuzufügen - nichts. Ich habe den Wert der Devise-Instanzvariablen @minimum_password_length überprüft und es ist null. Irgendwelche Vorschläge?Rails/Devise/Bootstrap: Zugriff auf @minimum_password_length im Anmeldemodal fehlgeschlagen
