Hello, When I create a select in a form, I get this error: wrong argument type String (expected Module) I know that ''type'' is a reserved word for STI and that''s what I want: a select box to choose the right type of Vehicule object: TYPES = [ ["Car", "Car"], ["Truck", Truck"], ["Bike", "Bike"] ] and <%= options = [["Type", ""]] + Vehicule::TYPES select(''vehicule'', ''type'', options) %> What did I miss?
