title: Heroku Friendly Ruby Scraper (with AJAX)?
body: <p>So I'm trying to write a small unofficial API in Ruby to pull data from a site.  I like Mechanize, but all the data I need from the page is generated by AJAX so Mechanize doesn't see it at all.  What can I use to render a page with JavaScript so that I can scrape the data?  I think something like <a href="https://github.com/makinacorpus/spynner" rel="nofollow">spynner</a> but for Ruby would do the trick.  </p>
  
  <p>I would also like to play with Heroku, so I'm looking for something that could be deployed there, which leads me away from something like <a href="http://watir.com/" rel="nofollow">Watir</a>.</p>
  
  <p>Does anything like this exist?</p>
  
  <p><strong>Update</strong></p>
  
  <p>For clarity, I'm trying to pull workout data from a <a href="http://www.fitocracy.com/profile/DorkRawk/" rel="nofollow">Fitocracy profile page</a>.</p>
  
  <p>You may need an account before you can view the page, but basically all the workout data is displayed via JavaScript inside a page shell.</p>
