How to find that the content is truncated?

Question

I\'m trying to build a blog app and the problem is when I use tag \'truncatewords_html\' in my template to truncate posts longer than specified number of words, I need to li

{% ifnotequal post.body|truncatewords_html:30|length post.body|truncatewords_html:31|length %}
