SELECT e.*, COUNT(c.id) as comments FROM blog_entry e LEFT JOIN blog_comment c ON e.id = c.entry_id GROUP BY e.id, e.name, e.name_slug, e.date_published, e.category, e.image, e.body, e.is_published, e.views, e.subscription_sent ORDER BY e.date_published DESC LIMIT 15;

from project.blog.models import Entry, Comment

def index(request):
    latest_entry_list = Entry.objects.filter(is_published=True).order_by('-date_published')[:15]
    return render_to_response('blog/index.html', {'latest_entry_list': latest_entry_list)

from project.blog.models import Entry, Comment

  def index(request):
    latest_entry_list = Entry.objects.filter(is_published=True).order_by('-date_published')[:15]
    latest_entry_list_comment_count = [(x, x.count()) for x in latest_entry_list]
    return render_to_response('blog/index.html', {
         'latest_entry_list': latest_entry_list,
)

{% for entry in latest_entry_list %}
    Entry: {{entry.0}}
    Comment count: {{entry.1}}
