right, templates are not python :) you can't do that, and it's on
purpose: that kind of fiddling around with the model is best done in
the view, not in the template.
So... instead of doing e.g.
documents = Document.objects.all()
tag_dict = {}
for document in documents:
tag_dict[document.uid] = DocumentTag.objects.filter(docid=document.uid)
and passing those two into the template, you could do something along
the lines of
documents = [dict(object=document,
tags=DocumentTag.objects.filter(docid=document.uid))
for document in Document.objects.all()]
and then in the template, you do
{% for document in documents %}
{{ document.object.content }}
{% for doctag in document.tags %} {{ doctag.tagid }} {% endfor %}
{% endfor %}
this is assuming there is some reason for you not to modify the
Document class to give it the appropriate methods or attributes to
access the related DocumentTag directly; if you could do that, life
would be much easier :)
