Transform DateTime into simple Date in Ruby on Rails

I have a datetime column in db that I want to transform into a simple date when I show it to users. How can I do that? def shown_date # to_date does not exist, but is what I am looking for self.date || self.exif_date_time_original.to_date end

DateTime#to_dateはActiveSupportでサポートしてるらしい。助かった。
