Um settings zu ändern, erst die Rails Console öffnen
zammad run rails c
… und dann die gewünschten settings abfragen und dann ändern:
Setting.get('ui_ticket_create_available_types')
=> ["phone-in", "phone-out", "email-out"]
Setting.set('ui_ticket_create_available_types', ["phone-in", "email-out"])
Setting.reset_change_id: set new cache, 817810699
Setting.set('ui_ticket_create_available_types', ["phone-in", "email-out"])
=> true
irb(main):008:0> Setting.get('ui_ticket_create_available_types')
=> ["phone-in", "email-out"]
