What should I be using for sitemap generation for rails on heroku?

问题

As a beginner to rails, I'm finding the generation of sitemaps on Heroku to be extremely daunting due to its read-only limitations. However, a sitemap is fundamental to my website as its success is based on SEO.

I have tried dynamic_sitemaps gem however soon removed it as I realised it had no documentation for heroku use. I then used the sitemap_generator gem which had coverage of heroku integration using several gems and external platforms such as Amazon S3. The problem however is that as a beginner I'm running into issues and finding it hard to get past them.

Is there a solution I can use easily generate sitemaps for consistent content such as blog posts on the heroku platform? I really want to get up and running and feel this could take a while to configure if I have to use the methods I've already attempted.

Thanks!

try like this

Controller

class SitemapController < ApplicationController


layout nil

def index
  @static_pages = [jobs_url, advertising_url, join_url]
  @offers = Offer.all

  respond_to do |format|
    format.xml
  end
end

end

View

    xml.instruct!
xml.urlset(

) do
  @static_pages.each do |page|
    xml.url do
      xml.loc "#{page}"
      xml.changefreq("monthly")
    end
  end
  @offers.each do |offer|
    xml.url do
      xml.loc 
      xml.changefreq("daily")
    end
  end


end

Route

 get 'sitemap.xml', :to => 'sitemap#index', :defaults => { :format => 'xml' }

I figured out a small trick that makes it possible to dynamically generate the sitemap file but persist it for later calls on Heroku.

It works great for small\medium size projects, if you have a big\huge project and thousand of pages that changes endlessly , please consider using S3 to store the sitemap file.

Those are the steps:

use the sitemap_generator gem as instructed here https://github.com/kjvarga/sitemap_generator
after bundle, run rake sitemap:install, it will create a config/sitemap.rb file for you
edit the config/sitemap.rb file to look like this

SitemapGenerator::Sitemap.default_host = [your host name goes here]

SitemapGenerator::Sitemap.public_path = File.join(Rails.root, 'tmp').to_s

SitemapGenerator::Sitemap.compress = false

SitemapGenerator::Sitemap.create do

[all your site pages add commands goes here]

end

regarding the host name, I suggest it to be "#{ENV['HOST_PROTOCOL']}://#{ENV['HOST_NAME']}" (and of course add the appropriate environment variables) so you could change it on different environments.
regarding compress, start with false, make sure all is working great for you and change it later if it is a big file.

create your sitemap controller file - app/controllers/sitemap_controller.rb
Edit the sitemap controller file to look like this

require 'rake'

class SitemapController < ApplicationController
  def index
    file_name = File.join(Rails.root, 'tmp', 'sitemap.xml').to_s
    
    unless File.exist?(file_name)
      Rails.application.load_tasks
      Rake::Task['sitemap:refresh:no_ping'].invoke
    end
    
    # it's better to be safe than sorry 
    if File.exist?(file_name)
      respond_to do |format|
        format.xml { render file: file_name }
      end
    else
      render file: 'public/404.html', status: :not_found, layout: false
    end
  end
end
