Render JSONp format

geoff · June 18, 2010, 10:10am

I see that rendering json arrays is very simple but JQuery needs to
have a jsonp format for cross domain requests.

is there a way to have rails output in the jsonp format?

Thanks in advance

Just a quick google search on “jsonp rails” brings up:

github.com

rack/rack-contrib/blob/cfee6eefe8291d0aa3c70a12b3b2cc350ec09beb/lib/rack/contrib/jsonp.rb

module Rack

  # A Rack middleware for providing JSON-P support.

  #
  class JSONP

    def initialize(app)
      @app = app
    end

    # Proxies the request to the application, stripping out the JSON-P callback
    # method and padding the response with the appropriate callback format.
    #
    # Changes nothing if no <tt>callback</tt> param is specified.
    #
    def call(env)
      status, headers, response = @app.call(env)
      request = Rack::Request.new(env)
