html - How to do ModelName.objects.filter in html

Question

I'm trying to eliminate the amount of code I need to put in my view and want to do this in my html file:

{% 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 %}

I am passing my article model and list of c as context in my view.

But it gives me this error:

    TemplateSyntaxError at /admin-dash/

Any idea how to do this? I think it's some sort of syntax. Thanks!
