Decouple Chartkick from Railties? about chartkick

[ankane]

I'll see if I can get it working with Padrino. Don't think it'll be too difficult.

Try the padrino branch https://github.com/ankane/chartkick/tree/padrino

Danke! Will let you know how it works

A couple of Padrino specific notes:

1. In the Gemfile, padrino must be listed before the chartkick gem or else you'll get this:

      /gems/ruby-1.9.3-head@trawl/bundler/gems/chartkick-54f1691b76f7/lib/chartkick/padrino.rb:2:in `<class:Application>': undefined method `helpers' for Padrino::Application:Class (NoMethodError)
   

2. The Padrino helper javascript_include_tag has apparently a different implementation than in Rails, because:

   <%= javascript_include_tag "//www.google.com/jsapi"%>
   

Resolves to:

   <script src="//www.google.com/jsapi.js" type="text/javascript"></script>

i.e. it wrongly assumes that the call should include the .js extension...This can be "fixed" by prepending the scheme (e.g. https:). Obviously, not chartkick's concern, but just a note for anyone trying to follow the README exactly.

Awesome, thanks for the detailed notes! I'll be sure to add them to the readme before this is merged.
