Rails, send data to a facebook app and get this data on my app

I know that I need to use the data like this, in order to send data to my facebook canvas app:

FB.init({appId: '#{Facebook::APP_ID}', xfbml: true, cookie: true});
FB.ui({  method: 'apprequests', message: 'Invite Friends to Blabloo...',
           data: '{\"draw_token\":\"#{@draw.token}\",\"invitation_token\":\"#{current_kid.invitation_token}\"}',
    exclude_ids: #{@draw.get_invited_ids_for current_kid}},handle_fb_callback);

and this send a Facebook invitation, that show you my registration form inside a cavas Facebook app, now on this registration form, on my new action, I need to get this draw_token and invitation_token.

How can I get this information?

NOTE: I'm using the koala gem

This data field that you sent is specific for that request you send to the user.

Here are the steps to follow to work with this:

  1. When the recipient clicks the requests and redirected to your application with the request_ids parameter, you should then get the data for the requests.

  2. To get the requests from the user, make the call-

    {user-id}/apprequests

  3. You will get a list of the requests and the data for each one (if any).

  4. The requests are accumulated and of-course cannot disappear by itself, so you need to delete the request once the user has accepted. To delete a request, make the call-

    /{request-id}?method=delete

You can see this example from the developers site.
