I wanna know how to sort blog articles in descending order.

[MM12]

Hello!
I would like to sort my blog articles in descending order, that is, in order of oldest posting date.
I edited bolog-listings module file as below, but they don't work.

{% for c in contents |sort(attribute='publish_time') %}
      {% if loop.index0 < remaining_cols %}
        {# initial columns #}
        {% do initial_posts.append(c) %}
      {% else %}
        {# regular columns #}
        {% do remaining_posts.append(c) %}
      {% endif %}
 {% endfor %}

{% for c in contents |reverse %}
      {% if loop.index0 < remaining_cols %}
        {# initial columns #}
        {% do initial_posts.append(c) %}
      {% else %}
        {# regular columns #}
        {% do remaining_posts.append(c) %}
      {% endif %}
 {% endfor %}

How should I edit the module file?
thanks in advance.

For the reverse, try removing the space before the |Reverse. This will only reverse the order of posts displayed on the current page. If you have pagination, then it won't sort through the other pages. 

{% for c in contents|reverse %}
      <article class="index-article">
	<div class="blog-listing">
	{% for tag in post.tag_list %}
	{% if loop.index == 1 %}
	<h2>{{ tag.name }}</h2>
	{% endif %}
	{% endfor %}
	</div>
	
	<div class="Listing-content">
		<p class="title"><a href="{{post.absolute_url}}">{{post.name}}</a></p>
		<p class="exerpt">{{ post.meta_description }}</p>
	</div>
</article>
{% endfor %}

 For sort, try

HubL filters (hubspot.com)

{% for c in contents|sort(True, False, "publish_date") %}

{% endfor %}

Thank you for answering.
The"|Reverse" simply reverses the order of the pages. It was helpful. thank you.

Aye. The sort method is probably your best bet. See the example in my previous post and the link I provided, and let me know how you get on.

Hi @MM12 , 

To control the order of how the posts are displayed, you can use the sort filter:

{% for c in contents|sort(True, False, "publish_date") %}

The very first parameter indicates whether the order needs to be reveresed.

Hope this helps!

Thank you for answering.
I tried the code below first, but the ascending order remained the same.
Please let me know if there is anything else that needs to be corrected.😭

{% for c in contents|sort(True, False, "publish_date") %}
      {% if loop.index0 < remaining_cols %}
        {# initial columns #}
        {% do initial_posts.append(c) %}
      {% else %}
        {# regular columns #}
        {% do remaining_posts.append(c) %}
      {% endif %}
{% endfor %}
