title: Rails Server restart every time I make a change
body: <p>I have a module file that I need to use for my rails project. When I make a change to any Rails models, views, controller etc the server doesn't need to restart. but when I make a change in that module I need to restart the server.</p>
  
  <p>The <code>module.rb</code> does not inherit anything from Rails classes.</p>
  
  <p><strong>The structure is this:</strong></p>
  
  <pre><code>class_1.rb &lt; class_2.rb includes module.rb
  </code></pre>
  
  <p><code>class_1.rb, class_2.rb are also not ActiveRecord classes</code>.
  They are all located in my models' directory.</p>
  
  <p>My <code>config/enviroments/development.rb</code> file is correct, as it has this:</p>
  
  <pre><code>  config.cache_classes = false
  </code></pre>
