Model's static methods are causing "undefined method" erros when running through custom rake tasks in Rails 3

My rake looks like this:

task :cron => :environment do
  Email.signup_email_reminder  
end

And my Email.signup_email_reminder methods looks like this:

class Email
include ActiveModel::Validations  
include ActiveModel::Conversion  
extend ActiveModel::Naming
.
.
.
def self.signup_email_reminder
  User.any_in(:status => [:status1, :status2]).each do |user|      
    puts Data.get_country_code(user.locale).upcase
  end
end
.
.
.
end

the method get_country_code is a static class in the model Data:

class Data

  def self.get_country_code(locale)
    .
    .
  end
.
.
.
end

But every 开发者_高级运维time I run the rake I get an error saying that the get_country_code method does not exist :(

$ rake cron --trace
(in /Volumes/alexandre.ponsin/Documents/Project/TextMaster.com)
** Invoke cron (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute cron
rake aborted!
undefined method `get_country_code' for Data:Class

I don't know what to do here :(

My guess is namespace collision. There's already a class called Data, so you may want to think about renaming your model.
