Django - Shorten text content retrieved in html template

Question

I would like to know how to shorten text content retrieved to get a preview instead of getting a block of text in the html template

From: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

To:

aaaaaaaaaaaaaaaaaaaaaaaaaaa....

The code that is used to retrieve the contents is :

   <a class="list_content" href="/qna/view" onclick="document.forms['q_title_{{ q.id }}'].submit(); return false" title="{{ q.content }}">{{ q.content }} </a><br/>

Many thanks!

Answer 1

If you are using Django 1.4, truncatechars filter will be the best way to go:

{{ q.content|truncatechars:25 }}

Answer 2

truncatechars template filter for django 1.4

Answer 3

Assuming that "q.content" is a string you could use the slice command:

{{ q.content|slice:":255" }}
