title: What is the equivalent of "none" in django templates?
body: <p>I want to see if a field/variable is none within a Django template. What is the correct syntax for that?</p>
  
  <p>This is what I currently have:</p>
  
  <pre><code>{% if profile.user.first_name is null %}
    &lt;p&gt; -- &lt;/p&gt;
  {% elif %}
    {{ profile.user.first_name }} {{ profile.user.last_name }}
  {% endif%}
  </code></pre>
  
  <p>In the example above, what would I use to replace "null"?</p>
