title: Concatenate string and UUID in Django Template
body: <p>I am trying to concatenate the UUID of a record with a base URL to create a scannable QR code that will link to the direct record on the website.  When trying to concatenate the two it fails and yields nothing.</p>
  
  <p>The relevant part is device.id which is a UUID for the device.  I've string |stringformat:"s" as well and that didn't work.  I don't know what the best practice to do this is and am struggling.</p>
  
  <pre><code>&lt;div class="row"&gt;
      &lt;div class="col-xs-12 text-center"&gt;
          {% with "http://127.0.0.1:8000/ims/device/"|add:device.id as deviceurl %}
          {% qr_from_text deviceurl size=25 %}
          &lt;p class="small text-center"&gt;{{deviceurl}}&lt;/p&gt;
          {% endwith %}
          &lt;p class="small text-center"&gt;{{ device.id }}&lt;/p&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
