Timber Wordpress display post in each category

Question

I use Timber plugin with Wordpress. I would like to create a loop which display 4 articles in each category.

publications.php

$context = Timber::get_context();
$post = new TimberPost();

$cat_id = wp_get_post_categories($post->ID);
$context['each_cat'] = Timber::get_posts(array('cat' => $cat_id[0], 'posts_per_page' => 4));

Timber::render( array( 'publications.twig', 'page.twig' ), $context );

publications.twig

{% for category in each_cat %}
<h2 class="title">{{category.name}}</h2>
    <article class="article--box">
        {% include "bloc_preview.twig" %}
    </article>
{% endfor %}

The include bloc_preview.twig is a preview of each post.

First off, @jandon thanks for asking these on StackOverflow (instead of clouding-up the GitHub issues with support Qs). The easiest way to accomplish what you're looking for is to use the .posts method on your term objects. Based on your example, you can do this all in Twig...

publications.twig

<h2>{{ post.title }}</h2>
<h3>Related Posts</h3>
{% for term in post.terms('category') %}
    <h3>Related Posts in {{ term.name }}</h3>
    <ul>
        {% for child_post in term.posts(4) %}
        <li><a href="{{ child_post.link }}">{{ child_post.title }}</a></li>
        {% endfor %}
    </ul>
{% endfor %}
