title: Calling a ruby action/method without redirecting
body: <p>I have a action called <code>new</code> in ConversationsController. I also have a view for it, <code>new.html.erb</code>, which has the following:</p>
  
  <pre><code>&lt;%= button_to "New", action: "save_it" %&gt;
  </code></pre>
  
  <p>In ConversationsController I have one more action, <code>save_it</code>, which is doing some action on a Redis database. </p>
  
  <p>Everything here is working fine. When I click on button, the <code>save_it</code> action is running and the Redis database action is also happening successfully. </p>
  
  <p>The problem is I am being redirected to <code>save_it.html.erb</code>. Is there any way I can call <code>save_it</code> such as to only perform the database commands without redirecting anywhere else?</p>
