    <p>I'm using django-threadedcomments and django-voting in my project to achieve a Reddit-like comments voting system.</p> <p>I've set everything up correctly and I'm able to successfully record votes for each threaded comment and its children, however I'm a bit stuck as to how to sort the comments so that the comment with the highest score rises to the top.</p> <p>Would passing through a template tag be a solution? I've attempted this and returned a list where the items were ordered by <code>score</code> descending, however the parent-child relationship of the comments got messed up. Here is what I did:</p> <pre><code>class OrderByVotesNode(template.Node): def __init__(self, queryset_var, direction="desc"): self.queryset_var = template.Variable(queryset_var) self.direction = direction def render(self, context): key = self.queryset_var.var value = self.queryset_var.resolve(context) try: direction = template.Variable(self.direction).resolve(context) except template.VariableDoesNotExist: direction = "desc" model = value.model qn = connection.ops.quote_name ctype = ContentType.objects.get_for_model(model) by_score = model.objects.filter(id__in=[f.id for f in value]).extra(select={"score": """ SELECT coalesce(SUM(vote), 0 ) FROM %s WHERE content_type_id = %s AND object_id = %s.%s """ % (qn(Vote._meta.db_table), ctype.id, qn(model._meta.db_table), qn(model._meta.pk.attname))}, order_by=[(direction == "desc" and "-" or "") + "score"]) context[key] = by_score return u"" </code></pre> <p>Any help or suggestions on this would be greatly appreciated. Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
