Question

I’d like to show my top level categories if the parent is equal to one. The topcats is a queryset that contains category items. However the code starred below is not working. It is not finding any cat items with parent = 1. Any idea why?

{% for cat in topcats %}
    **{% if cat.parent == 1 %}**
        <a href ="/x/{{cat.id}}/dir/"><h3>{{ cat.category }}</a></h3>
            {% for each in topcats %}
                 {% if each.parent == cat.id %}
                    <h5>{{ each }}</h5>
                 {% endif %}
            {% endfor %}
    {% endif %}
{% endfor %}

Note: parent is a TreeForeignKey in the database

I’d say cat.parent is a model object.

This should work for you:

{% if cat.parent.pk == 1 %}

However, this is quite hackish, as the parent node’s id does not necessarily have a value of 1. The is_root_node() method is a better approach:

{% if cat.parent.is_root_node %}
