title: How can I use double curly brases in double curly brases in Django?
body: <pre><code>&lt;p&gt;&lt;i class=&quot;fas fa-print mr-3&quot;&gt;&lt;/i&gt;{{ contact.phone2|default_if_none:'{{ contact.phone }}'}}&lt;/p&gt;
  </code></pre>
  <p>I want a value on double curly braces if_none like above. But it makes an error.
  How can I use it, when Django gives <a href="https://docs.djangoproject.com/en/3.2/ref/templates/builtins/#default-if-none" rel="nofollow noreferrer">templage tag</a>?</p>
