What are some useful non-embedded Django tags?

Question

I am relatively new to Django, and I am trying to create my own toolkit for future projects. In my last project, when the built-in template tag did not do what I needed, I would turn the garbled mess into a template into a nightstand in this function. I will later find a template tag that would save me time and ugly code.

So what are some useful template tags that are not built into Django?

Answer 1

{% autopaginate queryset%} (http://code.google.com/p/django-pagination/). :

#views.py
    obj_list = News.objects.filter(status=News.PUBLISHED)
    # do not use len(obj_list) - it evaluate QuerySet
    obj_count = obj_list.count()

---

#news_index.html
    {% load pagination_tags %}
    ...
    # do not use {% if obj_list %}
    {% if obj_count %}
        <div class="news">
        <ul>
        {% autopaginate obj_list 10 %}
        {% for item in obj_list %}
            <li><a href="...">{{ item.title }}</a></li>
        {% endfor %}
        </ul>
        </div>
        {% paginate %}
    {% else %}
        Empty list
    {% endif %}
