This Ruby on Rails plugin implements an ActiveRecord validation macro to allow validating of UK Postcodes. It is based on the following regular expression.
gem install validates_as_uk_postcode
# environment.rb config.gem "validates_as_uk_postcode"
# Gemfile gem "validates_as_uk_postcode"
class MyClass < ActiveRecord::Base validates_as_uk_postcode :postcode end
class MyClass < ActiveRecord::Base validates :postcode, :uk_postcode => true end
