This hopefully is a pretty easy question. My endgoal is to be able to view my database entries in a table which I can sort via the column headers. I have read the documentation on cycle tags, but don't know they mean by 'row1' and 'row2' : {% for o in some_list %} <tr class="{% cycle 'row1' 'row2' %}"> ... </tr> {% endfor %} Secondly, how would I correctly implement it into my template?

So, the question is, are there any django template tags that can be abused to get information that users are not supposed to get? I'm most worried about the {% url %} tag. P.S. I noticed this question after filling out the title, however, my question is slightly different. I will probably allow no HTML

How to ensure that all html-tags were closed? The problem arises because I want create some sort of excerpt for every article. For example someone writes an article like this: Hi everyone, I'm just an article and I have few <strong>tags</strong> inside <em>of me</me> If I cut this message just after "tags", I get an unclosed tag . How can I check with Django all user's input text before saving it to DB? In Django 1.7, there is a specific template filter called truncatechars_html : Similar to truncatechars, except that it is aware of HTML tags. Any tags that are opened in the string and not
