How to add High Voltage static pages to your sitemap file
High Voltage is a fantastic gem for adding static pages to your Rails app. I’m using it extensively on a project that has a large number of static, style-heavy pages that don’t make sense to serve from the database.
The other day my client asked me to add a sitemap XML file to the app that Google could consume (this is something that you can set up under Google Webmaster Tools that is supposed to help with site indexing).
I checked out several approaches for building sitemaps in a Rails app and settled on using the SitemapGenerator gem. This gem allows you to easily create paths to ActiveRecord resources. For example, if you want your sitemap to include all the FAQ pages you have, you could do something like this in the config file:
Faq.published.find_each do |faq| add faq_path(faq), lastmod: faq.updated_at end
But there’s no built-in way to include all your High Voltage static pages, as High Voltage doesn’t currently offer a way to get a list of all your pages.
So, I wrote a class you can put in your lib folder to do just that:
require 'find' class HighVoltagePages attr_reader :pages def initialize(ministry) @pages = get_pages end private def get_pages pages =  Find.find(content_path) do |f| pages.push url_path(f) if !directory?(f) && html?(f) && !partial?(f) end pages end def url_path(f) f.gsub(content_path, '').gsub(file_pattern, '') end def directory?(f) FileTest.directory?(f) end def partial?(f) File.basename(f).first == "_" end def html?(f) f.match(file_pattern) end def content_path Rails.root.join('app', 'views', HighVoltage.content_path).to_s end def file_pattern /\.(html)(\.[a-z]+)?$/ end end
Now all you have to do in your sitemap config file is iterate over those pages:
HighVoltagePages.new.pages.each do |page| add page end
