JSONP in Rails 3
Your URL:
http://localhost:3000/api/get_items?callback=awesome
In your api controller:
render :json => @items.to_json, :callback => params[:callback]
Result:
awesome(["item1", item2"]);
This gives you cross-domain JSONP. The callback variable in the URL is optional.
There’s no need to roll your own render_json.

Can you paste the request and response into gist.github.com and give me the link?

I had problems because Rails 3 ajax request (with Jquery) were expecting a JSONP response, making the browser to throw an error if normal JSON was received. This solved my problem.
Thanks for sharing the line.
