Question

I’m developing a Ruby on Rails application that has table attributes with special requirements. In the form they need to provide me a very special kind of date format.
the format in question is:

Year.month.day

I prefer to use the validates :format helper of Rails to make it a little cleaner, but i’m not very good with regular expressions. Any idea that enlights me?

Answer 1

Try

 validates :date, :format => { :with => /^[0-9]{4}[.][0-9]{2}[.][0-9]{2}$/, :message => "Invalid Date" }

Not the best practice. Also all this forget about bissext year and month’s number of days
