How do you do relative time in Rails?

Question

I\'m writing a Rails application, but can\'t seem to find how to do relative time, i.e. if given a certain Time class, it can calculate \"30 seconds ago\" or \"2 days ago\"

Answer 1

Since the most answer here suggests time_ago_in_words.

Instead of using :

<%= time_ago_in_words(comment.created_at) %>

In Rails, prefer:

  <%= comment.created_at.to_s %>

along with a jQuery library http://timeago.yarp.com/, with code:

$("abbr.timeago").timeago();

Main advantage: caching
