It would be exactly like Wikipedia's "Random Article" button. Takes you to a random webpage on the site.

<%= button_to "Random Article", article_path(random_article) %>

#app/helpers/application_helper.rb
class ApplicationHelper
   def random_article
      Article.order("RAND()").first.pluck(:id)
   end
end

With help from this article: Random record in ActiveRecord

Some more information would make this much easier to answer, but there are a few ways to do it. The best, in my opinion, would be something like this:

routes.rb:

resources :articles do
  get :random_article
end
#OR
get 'random_article' => 'some_controller#random_article', as: 'random_article'

articles_controller.rb

def random_article
  redirect_to article_path(Article.all.sample.id)
end

And on your page:

<%= link_to 'Random Article', random_article_path %>
