Rails Module issue - undefined method 'validates_email' for User:class

Question

I have a class called User, that needs to include a module. The class looks like this:

require 'sequel'
require 'modules/validations'

class User < Sequel(..)
  many_to_one :country
  includes ::Validations

  validates_email(:email)
end

The module is defined in a subfolder called modules. It has been added to the $LOAD_PATH and Ruby is no complaining about the loading. The module looks like this:

module Validations
   def validates_email(attr, options = {})
       email = super.email
   end
end

The error I am getting is : undefined method 'validates_email' for User:class

What am I missing to make this work properly?

If you want to use modules to define class methods you should use the extends method.

class User < Sequel(..)
  extend ::Validations
  validates_email(:email)
  ...
end

I suggest reading this article: http://railstips.org/blog/archives/2009/05/15/include-vs-extend-in-ruby/

This solved the problem for including the module thanks. Can I access the variables from my class in this module? – codingbunny Apr 16 '12 at 13:13
You should be able to access them normally – gmalette Apr 16 '12 at 14:21
Shouldn't this be "extend," not "extends?" – rpearce Apr 08 '13 at 19:47
Yes, it should have been. Fixed – gmalette Apr 08 '13 at 20:08
