loop through filtered collection in jekyll

Question

I try to do things like this in my post:

<ul class="articles-list">
  {% for post in site.posts | where:'group', post.group %}
    <div data-scroll-reveal="enter ease 0">
      {% include article-snippet.html %}
    </div>
  {% endfor %}
</ul>

but it loops through all my collection instead the only loops posts with special group.

Answer 1

You cannot use where filter in a loop.

But you can do :

{% assign posts = site.posts | where:'group', post.group %}

<ul class="articles-list">
  {% for post in posts %}
    <div data-scroll-reveal="enter ease 0">
      {% include article-snippet.html %}
    </div>
  {% endfor %}
</ul>
