Hi .. somebody around who is easy with Reg. Exressions. For me a nightmare.
I have to Validate this format: 0-0000 0000 and/or 0-0000 0000/0 and/or 0-0000 0000/00 Would be a great help.. I have got: (^\d-\d{4} \d{4}(/\d{2})?$)|(^I\d{8}$)|(^$) tried: validates :project_number, :format => { :with => /(^\d-\d{4} \d{4}(/\d{2})?$)|(^I\d{8}$)|(^$)/, :message => "Message"} But that seems to be not valid.
