如何计算DJANGO中的总选择?注释不起作用

我想显示一个选择字段的总数,所以基本上我做到了这一点,这是可行的,但不是给我总数就是重新填充字段。

Picture of how is showing now

而且必须如下所示:未开始:5或仅5

有人知道如何解决这个问题吗?

views.py

class UserPostListView(ListView):
    model = Post
    template_name = 'blog/user_posts.html'
    context_object_name='posts'
    paginate_by = 15

    def get_queryset(self):
        user = get_object_or_404(User, username=self.kwargs.get('username'))
        return Post.objects.filter(author=user).order_by('-date_posted')

    def get_context_data(self, **kwargs):
        context = super(UserPostListView, self).get_context_data(**kwargs)
        user = get_object_or_404(User, username=self.kwargs.get('username'))
        context['postuser'] = Post.objects.filter(author=user).order_by('-date_posted')[:1]
        context['posts'] = Post.objects.filter(author=user).order_by('-date_posted')
        context['postns'] = Post.objects.filter(author=user,status="NOT STARTED").annotate(dcount=Count('status')).order_by('status')
        return context

的HTML

            {% for post in postns %}
            <div class="col-auto col-ns-st padding-col-st"><span class="vertical-span"><i class="fa fa-circle color-ico-st"></i>&nbsp;{{ post.status }}</span></div>
            {% endfor %}

models.py

class Post(models.Model):
    NS= 'NOT STARTED'
    STATUS_CHOICES = (
        ('NOT STARTED','NOT STARTED'),
        ('IN PROGRESS','IN PROGRESS'),
        ('COMPLETE','COMPLETE'),
        )
    title=models.CharField(max_length=100)
    content=models.TextField(blank=True)
    author=models.ForeignKey(User, on_delete=models.CASCADE)
    status=models.CharField(max_length=40, choices = STATUS_CHOICES,default=NS)

    def __str__(self):
        return self.title


    def get_absolute_url(self):
        return reverse('post-detail', kwargs={'pk':self.pk})

    def __str__(self):
        return 'Post: {}'.format(self.status)
