Quick tip - Unicode validations
July 03 2006
Are you doing regular expression validations in your Active Record models like this?
class User < ActiveRecord::Base
validates_format_of :name, :with => /^\w{4,30}$/
end
Be aware that unless you enable unicode support these regular expressions will fail on many national characters.
Run the following to see this in action:
test_expressions.rb
puts 'jose' =~ /^\w{4,30}$/ # match
puts 'josé' =~ /^\w{4,30}$/ # no match
$KCODE = 'u'
puts 'jose' =~ /^\w{4,30}$/ # match
puts 'josé' =~ /^\w{4,30}$/ # match
So in order to allow national character support in you apps simply add the following line to your environment.rb:
environment.rb
$KCODE = 'u' # enable unicode support
Now your Active Record models can truly validate in style.
