【问题描述】:
我正在尝试消除需要放入视图中的代码量,并希望在我的 html 文件中执行此操作:
{% for committee in c %}
{% for article in Article.objects.filter(committee=committee) %}
<a class="post-link" href="{% url 'update' id=article.id %}">{{article.title}}</a>
{% endfor %}
{% endfor %}
我正在传递我的文章模型和 c 列表作为我认为的上下文。
但它给了我这个错误:

知道怎么做吗?我认为这是某种语法。谢谢!
