Re: Recursion in templates... again
It's not so hard to do recursion using templates as well as without them.
1. Write a template tag that takes one menu item as a parameter. I
don't have enough time to write the whole tag this time, but the
example usage should be like this:
{% load recursive_menu %}
{% menu root_category %}
2. It should return the list of its children parsed in an HTML
template or an empty string, if it has no children.
3. The HTML template should include the same template tag for each child.
{% load recursive_menu %}
{% if category.child_set.count %}
{% for item in category.child_set.all() %}
{{ item }}
{% menu item %}
{% endfor %}
{% endif %}

We have chosen the latter, which sometimes means you have to compromise on the former. PHP, for example, does it the other way around. You might say that this situation could be handled "if only we had template recursion", but then there would be other cases which are not handled and before you know it, the template language is Turing complete.

Re: Recursion in templates... again
I've implemented a similar hierarchy for categories in Satchmo using elementtree.

Re: Recursion in templates... again
Sorry, I didn't find a perfect solution, but I think that it can be done. You can use the "unordered list" filter in the template and fill an array in the view using recursive methods. Then you pass the array to the filter and it's done. You can also create your own filter tag, is not difficult, you can find some info in the section "extending the template system" http://www.djangoproject.com/documentation/templates_python/#extending-the-template-system and in the several files under the django installation path: They're in django/template/defaultfilters.py and django/template/defaulttags.py, respectively. I hope this help you. Adrian Ribao.

Recursion in templates... again
Hello, I have been looking around about some information about how to
do recursion in templates but what I found didn't help me.
This is the case:
class Menu(models.Model):
id = models.AutoField('id', primary_key=True)
parent = models.ForeignKey('self','id',null=True,blank=True)
name = models.CharField(maxlength=200)
And the plan is to create a menu like this:
- Entry 1
-- Subentry 1_1
-- Subentry 1_2
sub_Subentry 1_2_1
- Entry 2
...
I have created a custom tag to manage this but so far I only have this
in the template:
{% for entry in menu_list %}
{{ entry }}
{% endfor %}
and the customtag def is:
def menu(pos):
menu_list = Menu.objects.all()
return {menu_list': menu_list}
I have no idea how can I solve this problem, I have seen some posts
about this, but no clean solution.
Thank you!
