Django while loop

问题

I wonder if there's any way to do a while loop in django (I think that's what I'm after)?

What I'm trying to do is a nestled ul/li list.

The list is generated by a for loop in a for loop. But since some elements in the second for loop has more child's I want to iterate or them to and so on until all child nodes are iterated out. Only way I found so far is to have another for loop. But this seems not to generic and quite repetitive. And I need to know how many "levels" of child's there are.

This is what it look's like now:

<ul>
    {% for item in items %}
        <li>
            {{ item.name }}
            {% if item.childs %}
                <ul>
                    {% for child in item.childs %}
                        <li>{{ child.name }}</li>
                    {% endfor %}
                 </ul>
            {% endif %}
        </li>
    {% endfor %}
</ul>

Or is there a smarter way to send the data to the template? Can one do this with some kind of for/while loop?

Turn the list into an inclusion tag, then include it in itself.

Sounds like recursion could solve your problem if you want to delve down into an 'unknown' depth of child elements? There are quite a few posts on this out on t'internet if you search...

Maybe think about: https://docs.djangoproject.com/en/dev/ref/templates/builtins/?from=olddocs#unordered-list ?
