Bolt: Get 'related records' from a content type, but only display the ones with a 'datetime' that's after today.

related.twig

{% set relatedrecords = record.related('agenda') %}
{% if relatedrecords is not empty %}
    <ul>
       {% set now = "now"|date('Y-m-d') %}
       {% for related in relatedrecords if related.datetime >= now %}
      <li>
         <a href="{{ related.link }}">
         <p>{{ related.datetime|localdate('%A %e %B %Y') }}</p>
         <p><strong>{{ related.title }}</strong></p>
         <p>{{ related.lokatie|striptags }}</p>
         </a>
      </li>
      {%  endfor %}

</ul>
{% endif %}
