CloudFlareLocalizable

If you're using CloudFlare you can easily get the country of users requesting your pages. This is a very basic gem to help you get the country information in your Rails applications when you're using CloudFlare services.

Add this line to your application's Gemfile:

gem 'cloudflare_localizable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cloudflare_localizable

You should include CloudFlareLocalizable in any Rails controller that needs country information. You get a helper method called cf_country to be used whenever you need to know the country of the user.

class ExampleController < ApplicationController
  include CloudFlareLocalizable

  def index
    cf_country.code # => "BB"
    cf_country.name # => "Barbados"
  end
end

Because it is a helper method you can use it in the views if you want.

<ul>
  <li>Code: <%= cf_country.code %></li>
  <li>Name: <%= cf_country.name %></li>
</ul>

If something goes wrong, or the client is trying to spoof an unknown location, or CloufFlare can't get the country information for a given IP address then you get code XX and name Unknown.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
