title: Rails logger messages not showing in development log
body: <p>My development log seems to be working fine (it shows each asset that's loaded etc.) but it won't show any messages I put in code. I have:</p>
  
  <pre><code>   Rails.logger.debug "My debugging message"
  </code></pre>
  
  <p>in a method of my controller. The method is called but the message does not show in the development log. This seems pretty basic and I can't see where I'm going wrong. Any ideas?</p>
