Hi I have also same doubt ,can we write the validations for non
database fileds
in model

Please give me reference

Thnks

There is many different validations that are available to you out of the
box.

The one for use with regular expressions is
validates_format_of
docs at
http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#M000817

If none of those meet your exact needs you can always write your own
with
the validate method
