title: Rails rescue_from stops execution flow
body: <p>I'm having problems using the rescue_from</p>
  
  <pre><code>class SimpleError &lt; StandardError; end
  
  before_action :raise_exception
  rescue_from SimpleError, with: :rescue_exception    
  
  def raise_exception
      raise SimpleError
  end
  
  def rescue_exception
      log $!
  end
  
  def index
      @unreachable_code = true
  def
  </code></pre>
  
  <p>In this code as you can see I simply raise an exception before the action starts, that is caught by the rescue_exception method. The problem is that after I catch the exception the application flow stops and the action code is never reached.
  Is it possible to continue the execution after the exception is rescued?</p>
