I'm trying to retrieve a m2m relation from a blog entry. It should give a
list of entries with the same categories. Below works when I work in the
shell.
from content.models import Entry
qs = Entry.objects.all()
obj = qs[0]
related = Entry.objects.filter(categories=obj.categories.all())
The obj simulates a single Entry in a template for use in the shell.
I'm trying to put this in a custom template tag, so a list of related
entries can be shown with a blog entry. I cooked up the following:
{% load content_tags %}
{% get_related_entries content.entry from*object.categories.all
* as related_entries %}
{% for item in related_entries %}
<p><a href="{{ item.get_absolute_url }}">{{
item.title }}</a>
{% endfor %}
This isn't working though. I'm not sure how to do this, even after
(re)reading Django-books and documentation. When I don't apply a filter and
the following in the Node render() works:
context[self.varname] = self.model.objects.all()
Obviously I get a list of all entries, without any filter. I'm pretty sure
it has to do with the object.categories.all (which is a list of all
categories) in my template tag and the use of it in the parser/Node. How can
I achieve this?
PS:
I didn't include any of my (now many) variants of code I tried on purpose. I
suspect I'm following an entirely wrong approach and don't want to focus
attention at wrong code.
