I’m having a problem extending ActiveRecord with custom validations
based on the “Write Custom Validations” recipe from Advanced Rails
Recipes. As far as I can tell, I’ve followed the instructions exactly
but for some reason this isn’t working and it’s driving me crazy.
I’ve tried making the methods in the custom validations module class
methods (self.validates…) as well as the way they are below (which
is the way they are in the instructions).
Any suggestions?
Thanks!

lib/custom_validations.rb
module CustomValidations
def validates_phone(*attr_names)
attr_names.each do |attr_name|
validates_format_of attr_name,
:with => /^[()0-9- +.]{10,20} *[extension.]{0,9} *
[0-9]{0,5}$/i,
:message => “invalid”
end
end
def validates_email(*attr_names)
attr_names.each do |attr_name|
validates_format_of attr_name,
:with => /(^([^@\s]+)@((?:[-_a-z0-9]+.)+[a-z]{2,})$)|(^$)/
i,
:message => “invalid”
end
end
end
ActiveRecord::Base.extend(CustomValidations)
config/environment.rb
Be sure to restart your server when you modify this file
Uncomment below to force Rails into production mode when
you don’t control web/app server and can’t set it the proper way
ENV[‘RAILS_ENV’] ||= ‘production’
#normal environment.rb stuff
end
require ‘custom_validations’
models/user.rb
class User < ActiveRecord::Base
validates_email :email
end
