template中引用外键值的处理

models

class Article(models.Model):
    title = models.CharField(max_length=100, verbose_name='文章标题')


class Org(models.Model):
    name=models.CharField(max_length=30, verbose_name='公司名')


# 因为在博客项目中, 每个用户都是作者, 所以这里用author来表示用户
class Author(models.Model):
    username = models.CharField(max_length=30, verbose_name='用户名')
    articles_collected = models.ManyToManyField(to=Article, verbose_name='收藏的文章')
    org = models.ForeignKey(to=Org, on_delete=models.CASCADE, null=True)

views

def orgs(request):
  orgs = Org.objects.all()
  for i in range(len(orgs)):
    orgs[i].counts = orgs[i].author_set.all().values('articles_collected').count()

  return render(request, "web/show-org.html", locals())

html

<table class="table"  >
  <thead>
    <tr>
      <th>名称</th>
      <th>作者数量</th>
      <th>文章数</th>
    </tr>
  </thead>
  <tbody>
    {% for row in orgs %}
      <tr>
        <td>{{ row.name }}</td>
       
        <td>{{ row.author_set.all.count }}</td>

        <td>{{ row.counts }}</td>
      </tr>
    {% endfor %}

主要看文章数row.counts是怎么处理显示的
