title: How do I make Rails 3.1 concatenate assets in development mode?
body: <p>I am having trouble getting the asset pipeline to concatenate (but not compress!) assets in development. The idea is that I can stop making 70+ requests for tiny css/js files for every development page load, but still get to view a line number so I can figure out where problems are.</p>
  
  <p>My <code>config/environments/development.rb</code> has this, which I interpret the rails guide to mean that assets should be compiled into one file, but not compressed:</p>
  
  <pre><code>config.assets.compress = false
  config.assets.compile = true
  config.assets.digest = false
  config.assets.debug = false
  </code></pre>
  
  <p>But no dice: assets are still served individually instead of concatenated within application.js.</p>
  
  <p>Any help would be appreciated!</p>
