I wand generate a tree menu/sitemap.
How can i make a recursive loop in a template???

In jinja i can use the tag "recurse":
http://wsgiarea.pocoo.org/jinja/docs/loops.html#recursion

Here a jinja example:
------------------------------------------------------------------------
context = {'sitemap': [{'href': u'/Index/',
               'subitems': [{'href': u'/Index/PhpBBadmin/',
                             'title': u'phpBBadmin'}],
               'title': u'index'},
              {'href': u'/ExamplePages/',
               'subitems': [{'href': u'/ExamplePages/TextileExample/',
                             'title': u'complete tinyTextile examples'},
                            {'href': u'/ExamplePages/Testpage/',
                             'title': u'a testpage ;)'},
                            {'href': u'/ExamplePages/SourceCode/',
                             'title': u'SourceCode'},
                            {'href': u'/ExamplePages/Contact/',
                             'title': u'contact'},
                            {'href': u'/ExamplePages/SiteMap/',
                             'title': u'SiteMap'}],
               'title': u'example pages'},
              {'href': u'/Test/', 'title': u'test'}]}

template = """
<h1>Sitemap</h1>
<ul>
{% for item in sitemap %}
   <li>
     <a href="{{ item.href }}">{{ item.title|escapexml }}</a>
     {% if item.subitems %}
         <ul>{% recurse item.subitems %}</ul>
     {% endif %}
   </li>
{% endfor %}
</ul>
"""
------------------------------------------------------------------------

recurse used the for loop again with the subitems. So i can easy create
a recursion.

How can i do this in django?

The templates don't support that kind of functionality directly. You'll
probably want to create your own template tag that will do for you - you can
recurse to your heart's content in Python.

Check out the docs at
http://www.djangoproject.com/documentation/templates_python/ for a good
overview. Making one is really pretty straightfoward.

While I agree with Joseph that writing your own template tag to handle
this is pretty easy, it's worth noting that Jinja spun off of Django's
templating specifically to add things like recursion.

It won't be added to Django core, AFAIK.

I don't think this is so easy :(

I found this:
https://svn.greenpeace.org/projects/custard/browser/production/trunk/...

But i don't know how i can use this.

Why?
Everyone need this function, if you would like to build a sitemap with a
tree.

I think this feature should not be missing in the core. It's a very
useful function

You might contact one of these folks:
https://svn.greenpeace.org/projects/custard/browser/doc/copyright.html

But it looks like something like this would do:

x = { 'value':1, 'children': [
  { 'value': 2, 'children': []},
  {'value' : 3, 'children': [
     { 'value':4, 'children':[] }
     ]}
  ]}

{% recurse through children as node starting with x %}
...do something with node.
{% endrecurse %}

No, not everyone needs this.

If you do, consider using Jinja with Django.  The HttpResponse just
wants a string which Jinja is (of course) capable of creating.

As a programmer, I agree.  But the Django templating language is not
only for me, nor am I limited to the Django templating language.

No problem, the source is under the GPL and PyLucid is under GPL, too ;)

Thank you for your help! Now, i try it to use it ;)

The code is for an older django version.

If you want recursion in templates, why not just use Jinja?

Jeremy Dunck schrieb:

Jinja is super cool. But I would like to keep the PyLucid package small.

I thought with django i would choose a full features framework :(

It works pretty well for me and many others.  Writing a template tag
is a reasonable solution, IMHO.  :-/
