But what if my class is an inherited class? Maybe an example might explain clearer. Assuming I have 2 classes: class MadDate < Date def toDDMMYYYY(sep = "/") strftime(%d%m%Y") end end class Main def self.show d = Date.today d.toDDMMYYYY("-") end end And when i call, Main.show, it gives the same error "undefined method toDDMMYYYY". Is there then a way of working around inherited classes? -- Posted via http://www.ruby-forum.com/.
