Facebooker talk - Mar 2008 - Can someone tell me if this is possible

I''d like to make a call to the following URL passing my API_KEY.
Two questions

http://www.facebook.com/code_gen.php/v=1.0&api_key=MY_API_KEY

I''d like to access my stored api_key

1)      Can I do it from the following start point
         t_session = Facebooker::Session.create

        then somehow access the key


2)      I''m also trying to do the following from my Controller

 def temp_session

    t_session = Facebooker::Session.create

    t_session.secure_with!(self.facebook_session_key, self.facebook_uid, 0)

    return t_session

  end



    but I''m getting the following error

        undefined method `facebook_session_key'' for
#<FacebookerController:0x4aa6870>

For number one, you want to do something like this:

t_session = Facebooker::Session.create(Facebooker::Session.api_key,  
Facebooker::Session.secret_key)

Though I haven''t looked into the underlying code directly, I''m
guessing Facebooker::Session.api_key and secret_key are both loaded  
from your facebooker.yml file at load time.

For number two. If that method is in your controller and  
facebook_session_key is an attribute of your user model, then the  
problem is self.facebook_session_key is attemping to call  
facebook_session_key on the controller, not your user object. I would  
move that method to your user model and then call it in your controller.

class User < ActiveRecord::Base
   def restore_facebook_session
     return @facebook_session unless @facebook_session.nil?
     @facebook_session =  
Facebooker::Session.create(Facebooker::Session.api_key,  
Facebooker::Session.secret_key)
     @facebook_session.secure_with!(facebook_session_key,  
facebook_uid, 0)
     @facebook_session
   end
end

where facebook_session_key and facebook_uid are attributes of your User.

class FacebookController < ApplicationController
   def some_action
     @user = User.find(params[:id])
     @facebook_session = @user.restore_facebook_session

     # do stuff with your facebook session
   end
end

Thanks Joel:

   Does facebooker have a similar function to the following - to return facebook
generated session key

   facebook.auth.getSession ?


n  Thanks, Mike

The session key is accessible with "your_session.session_key". So, by
default in your facebook controller with the requisite ensure filters,  
you will have a session accessible via facebook_session. So, you would  
get it like this:

class FacebookController < ApplicationController
   ensure_application_is_installed_by_facebook_user

   def some_action
     @user = User.new
     @user.facebook_session_key = facebook_session.session_key
     @user.facebook_uid = facebook_session.user.uid
     @user.save
   end
end

Is that what you were after?
