Main navigation caching in Refinery CMS

main_navigation_caching_in_refinery_cms

Main menu cahing in Refinery CMS  >= 2.0.0

If you are in development mode, set config.action_controller.perform_caching = true in development.rb
Then create app/decorators/controllers/refinery/admin/pages_controller_decorator.rb:

# This is for main navigation fragment caching - do cache expiration after reordering pages
Refinery::Admin::PagesController.class_eval do
  after_filter lambda{::Refinery::PageSweeper.instance.sweep(page)}, :only => [:update_positions]
end

Then override /refinery/_header.html.erb, wrap render partial call with block:

<% cache "main_navigation_#{params[:locale]}" do %>

<% end %>

Create file page_sweeper_decorator.rb  with this code in your /app/decorators/sweepers/refinery folder

Refinery::PageSweeper.class_eval do
  def sweep(page)
    expire_cache # calling expire page cache protected method in Refinery::PageSweeper
    
    # This should be faster than RegExp matching
    Refinery::I18n.frontend_locales.each do |locale|
      expire_fragment("main_navigation_#{locale.to_s}")
    end
  end


  alias_method :after_create, :sweep
  alias_method :after_update, :sweep
  alias_method :after_destroy, :sweep
end
