title: Ad/Banner Management/Rotation for Ruby on Rails?
body: <p>I have a niche site that I'd like to sell banners for directly, rather than going through adsense.  I need a system to manage the whole process: displaying ads and an administrative interface to manage them.  It doesn't have to be anything terribly fancy, although open source is greatly preferred so that I can grow the system as needs be.  Since the site itself is in Rails, I would prefer something for that environment.  Googling turns up bunches of them in PHP, but the results are a bit polluted and I didn't have any luck finding one that was done in/for Rails.</p>
  
  <p>If I don't find one, I suppose I'll see what I can do to hack together something and release it myself under an open license.</p>
  
  <p>Another possibility is this: <a href="http://www.google.com/admanager" rel="noreferrer">http://www.google.com/admanager</a> - anyone have anything to say about it?  Is it right for someone just selling a few ads for a not-so-big site?</p>
  
  <p>Thanks,
  Dave</p>
