jquery - Create Rails Proxy for JSON -

i want asynchronously query foursquare api, not allow old $.get(). short term solution make helper gets data so:

def foursquare_info_for(venue_id)     res = net::http.get_response("api.foursquare.com", "/v1/venue.json?vid=#{venue_id}")     data = json.parse(res.body)     info = hash.new     info["mayor_name"] = "#{data['venue']['stats']['mayor']['user']['firstname']} #{data['venue']['stats']['mayor']['user']['lastname']}"     info["mayor_photo_src"] = "#{data['venue']['stats']['mayor']['user']['photo']}"     info["checkins"] = "#{data['venue']['stats']['checkins']}"     info end 

that works, i'd rather make proxy can jquery ajax request after page loads speed things bit. i'm pretty sure helper close need proxy working, i'm not sure need put proxy json on side in order able grab jquery.

am on right track creating proxy net/http?

where put proxy on side can access jquery get?

i think using net::http enough this.

i make class it. like:

class foursquareinfo < struct.new(:venue_id)    def info     { :mayor_name => mayour_name, :mayor_photo_src => mayor_photo_src, :checkins => checkins }   end    def mayor_name     "#{mayor_firstname} #{mayor_lastname}"   end    def mayor_firstname     mayor["firstname"]   end    def mayor     stats["mayor"]["user"]   end    def stats     data["venue"]["stats"]   end    def data     @data ||= json.parse(response.body)   end    def response     net::http.get_response("api.foursquare.com", "/v1/venue.json?vid=#{venue_id}")   end    # etc...  end 

and controller:

class foursquareinfoscontroller < applicationcontroller   def show     render :json => foursquareinfo.new(params[:id]).info   end end
