#after_save(page_localization) ⇒ Object

This is the business end. If the paths do have to be recached, we pile through all the decendent localizations and tell each of those to recache. Each of those will then also be observed and have their children updated as well.

def after_save(page_localization)
  if page_localization.paths_need_recaching? and !page_localization.page.children.blank?
    decendant_pages = page_localization.page.children
    
    decendant_pages.each do |d_p|
      decendants = d_p.localizations.find( :all , :conditions => {:locale_id => page_localization.locale_id})          
      unless decendants.blank?
        decendants.each do |l| 
          l.paths_need_recaching = true
          l.update_attributes(:path => "#{page_localization.path}/#{l.slug || l.page.slug}") 
        end 
      end
    end#loop  
  end
end

#before_validation(page_localization) ⇒ Object

Every time the localization is updated, we need to check to see if the slug has been updated. If it has, we need to update it’s cached path and also the paths for all it’s decendants.
