GoogleChartSSL

Including Google Charts in your SSL-protected site causes warnings about ‘Mixed Content’ (particularly in Internet Explorer). This Rack middleware allows you to point those img tags at a local path instead of Google. The image is retreived by your server then delivered to your client over your SSL connection.

Installation

gem intall google_chart_ssl

Usage

require 'google_chart_ssl'
use GoogleChartSsl

Or, if you are using Bundler, just add this to your Gemfile:

gem 'google_chart_ssl'

To use GoogleChartSSL in your Rails application, add the following line to your application config file (config/application.rb for Rails3, config/environment.rb for Rails2):

config.middleware.use GoogleChartSsl

Now, instead of making your chart request to chart.apis.google.com/chart, just send that request to /google_chart will be forwarded to google and returned over your server’s connection.

Example

<img src="http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World">

becomes:

<img src="/google_chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World">

Note on Patches/Pull Requests

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don’t break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
