This is exactly what I need, but I can't make it work...

I put the code in a template which I included in my main template, the first include is fine, but it doesn't go further.
It react like if "post" from "{% for post in thread %} " is empty (but it's not) and doesn't go inside the loop.

Does anybody have this kind of trouble?

thanks.

PS! I'm using it on a production system but just for admin/cms stuff, so I guess there's no real harm there. Wanted to have a menu using this (one of those nice superfish-style dropdown menus), but I suspect that that would REALLY kill the server (having to resolve this recursion on every single page call).

As for performance issue, I was probably too alarmist, especially now that Django actually can cache templates in memory once compiled. So you probably shouldn't worry.

But still, if you do want to go after performance, and you are rendering out a forum thread with a huge number of branches and nodes, it'll sure be faster to set something like an indentation-level attribute in your python code.

Is this a really bad idea or just not a good idea for a million-uniques-a-day site?

{% for category in categories %}
{{ category.name }}
{% with "list.html" as filename %}
{% with category.category_set.all as category %}
{% include filename %}
{% endwith %}
{% endwith %}
{% endfor %}

This causes the built-in server to completely shut down without an error. What am I doing wrong?

Why not use in production?
What could poooooosibly ever go wrong with a recursive call
