Is there an expiry_date column in the database? You can only put it in the controller if that column exists. However, if the expiry date is *always* +90 days then you should not put it in the database, but should provide an instance method in the model, something like def expiry_date self.issue_date + 90.days end Then you can say durc.expiry_date and will always get issue date + 90 days. The method may have to be a little more complex if issue_date can ever be nil.
