Threepwood

Allows cookies to be set and unset with simple command. To comply with EU law, users must explictly accept cookies before any cookies are placed on their devise. By including Threepwood, you block all cookie until you explicitly accept them. It currently only works with rails >=3 projects.

Installation

gem install threepwood

Usage

In your gemfile:

gem 'threepwood'

Create a partial saying that your site will use cookies

%p 
  This site uses cookies. 
  = link_to 'I accept cookies.', '/cookies_accept', :method => :put
  = link_to 'I decline cookies.', '/cookies_deny', :method => :put

Set up routes:

put "cookies_accept" => your_controller#cookies_accept
put "cookies_deny" => your_controller#cookies_deny

set up controller actions:

class YourController < ApplicationController
  def cookies_accept
    accept_cookies #this calls the threepwood method to allow cookies
    redirect_to home_path
  end
  def cookies_deny
    reject_cookies # this calls the threepwood method to remove the fact that the user has accepted cookies
    redirect_to home_path
  end
end

On your page (assume HAML):

= render :partial => 'your_message_about_cookies' unless @accepted_cookies

Alternatively add a static html page that proceeds your web app and call accept_cookies in a before filter on application_controller OR add a message to your terms and conditions and add accept_cookies to your login action

Disclaimer

Whereas every effort has been made to make this gem compliant with the EU cookie law, it does not guarantee that this approach is 100% compliant. You should check with your legal team and ensure that you have correct coverage.
