title: How to get "Application Trace" instead of full verbose backtrace in Rails?
body: <p>In Rails default error page of development environment, you can view three backtraces, 1. Application Trace, 2. Framework Trace and 3. Full Trace.</p>
  
  <p>But how can I get "Application Trace" in Rails controllers. Full Trace (exception.backtrace) is too much for me.
  Now I'm doing like this:</p>
  
  <pre><code>exception.backtrace.select {|line| line =~ /myappname/i }
  </code></pre>
  
  <p>Is this a correct way? Or are there other cooler ways to get it?</p>
