URL Shortening on Rails 3 with Bitly

For integrating with twitter you need to shorten url. I have used this gem

First add gem to your gemfile
gem bitly

and run
bundle install

Now add this to your controller
require ‘bitly’

philnash’s gem has support for the bit.ly version 2 and version 3 api. I have use version 3.

Create a new file config\initializers\bitly.rb and write this.
 
Bitly.configure do |config|
  config.api_version = 3
  config.login = "##############"
  config.api_key = "##################################"
end

That’s it from installation.

Here is code from controller. This is the example from the gem documentation
u = bitly.shorten('http://www.google.com') #=> Bitly::Url
 u.long_url #=> "http://www.google.com"
u.short_url #=> "http://bit.ly/Ywd1"
u.bitly_url #=> "http://bit.ly/Ywd1"
u.jmp_url #=> "http://j.mp/Ywd1"
u.user_hash #=> "Ywd1"
u.hash #=> "2V6CFi"
u.info #=> a ruby hash of the JSON returned from the API
u.stats #=> a ruby hash of the JSON returned from the API

Based on this your result is expected. if you want the short url try
bitly.shorten("http://domain.com/articles/#{id}").short_u
