rails-timeago provides a timeago_tag helper to create time tags usable for jQuery Timeago plugin.
Installation
Add this line to your application's
Gemfile:
gem 'rails-timeago', '~> 2.0'
And then execute:
$ bundle
Or install it yourself as:
$ gem install rails-timeago
To use bundled jQuery Timeago plugin add this require statement to your
application.jsfile:
//= require rails-timeago
This will also convert all matching time tags on page load.
Use the following to also include all available locale files:
//= require rails-timeago-all
If using a recent Rails with
rails-ujs, jQuery might not be present anymore. You need to add
jquery-railsto your
Gemfileand load it, e.g.:
//= require jquery //= require rails-timeago //= require rails-timeago-all
Usage
Use the timeago_tag helper like any other regular tag helper:
Available options:
date_only Only print date as tag content instead of full time. (default:
true)
format A time format for localize method used to format static time. (default:
default)
limit Set a limit for time ago tags. All dates before given limit will not be converted. (default:
4.days.ago)
force Force time ago tag ignoring limit option. (default:
false)
default String that will be returned if time is
nil. (default:
'-')
title A string or block that will be used to create a title attribute for timeago tags. It set to nil or false no title attribute will be set. (default:
proc { |time, options| I18n.l time, format: options[:format] })
All other options will be given as options to the time tag helper. The above options can be assigned globally as defaults using
Rails::Timeago.default_options limit: proc { 20.days.ago }
A global limit should always be given as a block that will be evaluated each time the rails
timeago_taghelper is called. That avoids the limit becoming smaller the longer the application runs.
I18n
rails-timeago 2 ships with a modified version of jQuery timeago that allows to include all locale files at once and set the locale via an option or per element via the
langattribute:
The following snippet will print a script tag that set the jQuery timeago locale according to your
I18n.locale:
Just insert it in your application layout's html head. If you use another I18n framework for JavaScript you can also directly set
jQuery.timeago.settings.lang. For example:
jQuery.timeago.settings.lang = $('html').attr('lang')
Do not forget to require the needed locale files by either require
rails-timeago-allin your
application.jsfile or require specific locale files:
//= require locales/jquery.timeago.de.js //= require locales/jquery.timeago.ru.js
Note: English is included in jQuery timeago library, but can be easily override by include an own file that defines
jQuery.timeago.settings.strings["en"]. See a locale file for more details.
rails-timeago includes locale files for the following locales taken from jQuery Timeago.
Your customized jQuery locale files must be changed to work with rails-timeago 2. Instead of defining your locale strings as
jQuery.timeago.settings.stringsyou need to define them like this:
jQuery.timeago.settings.strings["en"] = {
...
}
