How to display only the first two children in django-mptt?

Question

Django

There is this pattern:

{% recursetree product.comments.all %}
               {% with comment=node %}
                    <div class="comment-item_lvl-{{ comment.level|add:'1' }}">
                        {% include 'product/comment.html' %}
                    </div>
                {% endwith %}
                {% if not node.is_leaf_node %}
                      {{ children }}
                {% endif %}
 {% endrecursetree %}

How to set the output of only the first 2 descendants and not all?

Answer 1

Level empirically determine yourself

{% recursetree product.comments.all %}
    {% with comment=node %}
    <div class="comment-item_lvl-{{ comment.level|add:'1' }}">
        {% include 'product/comment.html' %}
    </div>
    {% endwith %}
    {% if not node.is_leaf_node and node.level <= 2 %}
        {{ children }}
    {% endif %}
{% endrecursetree %}

And in pursuit, it's better

{% recursetree product.comments.all %}
    <div class="comment-item_lvl-{{ node.level|add:'1' }}">
        {% include 'product/comment.html' with comment=node %}
    </div>
    {% if not node.is_leaf_node and node.level <= 2 %}
        {{ children }}
    {% endif %}
{% endrecursetree %}

Answer 2

{% recursetree product.comments.all | slice:":2" %}
