title: How can I hide params in view's url?
body: <p>I'm passing a change id as a parameter with a <code>link_to</code>:</p>
  
  <p><code>&lt;%= link_to 'Change', my_service_path(change: '1234567890'), method: :get%&gt;</code></p>
  
  <p>In the controller I have:</p>
  
  <pre><code>def my_action
     if params[:change]
       ...
       params.delete :change
  end
  </code></pre>
  
  <p>But when the <code>view</code> is displayed I still see
  <code>&lt;view url&gt;?change=1234567890</code></p>
  
  <p>How do I prevent <code>?change=1234567890</code> from showing in the url?</p>
