What is it you want to do with the ones they've voted on vs. haven't? If
you're going to hide the ones they've already voted on, just write a
query in the view method that only returns those and pass that to the
context. (Note: the view method, not the template. See Ivan's response.)
If they have to be in alphabetical order by title and you're going to
show all of them, add something to each one that indicates whether
they've been voted on. Your list could morph into a list of tuples where
the first item is a paper and the second item is a boolean indicating
whether the current user has voted.
Something like:
def display_votes(request):
all_papers = Paper.objects.all()
tuple_list = [(p, p.has_voted(request.user)) for p in all_papers]
...
Then in the template:
{% for paper_voted in tuple_list %}
{% if paper_voted.1 %}
stuff if they voted, paper is accessible as paper_voted.0
{% else %}
stuff if they haven't
{% endif %}
