[PATCH, TESTED] Allow to specify locale as variable

looks cool :)

do you like a push request Josh ?

we added a little hack to define seperate methods for each localized attribute.

for example: i have a post object, the content attribute is translated into german and english..

class Post
 translates :content
end

generates

Post.new.content_de and Post.new.content_en.

We use this to added a form with this 2 attributes to add translations to the post content. This just works seemless with the way how rails works with forms and attributes...

our code

module Ours
  module Globalize

def translates(*attr)
  attr.each do |name|
    I18n.available_locales.each do |locale|
      define_method "#{name}_#{locale}" do
        #globalize.fetch locale, name
        translations.select{|t| t.locale == locale}.first.try(name)
      end
      define_method "#{name}_#{locale}=" do |value|
        value = value.blank? ? nil : value
        globalize.write(locale, name, value)
        #self[name] = value
      end
    end
  end
  super
end

  end
end



class Post
  extend Ours::Globalize
  translates :content
end

not a big fan of this hack personally.

I've started a different path a while ago, you can find more at #6 [PENDING, PATCH, TESTED] Allow multiple translations to be set at once or even #10 [Feature] Validation and form to work nicer with locales
