[Facebooker-talk] How do you find user's friends that have installed your app?

[Nnanna Obuba]

Thanks. for anyone who is interested, here's the syntax as I used it  
to return an array of uids for friends of the current user who have  
installed your app

1. Using the facebooker method

@current_users =  
current_user.facebook_session.user.friends_with_this_app.map {|x| x.uid}

   2. Using FQL

         already_in = current_user.facebook_session.fql_query(
                 "SELECT uid FROM user WHERE uid IN (SELECT uid2 FROM  
friend WHERE uid1= #{current_user.facebook_id} ) AND is_app_user")
         @current_users = already_in.map  {|y| y.uid}


Of course if you want the user objects instead of the uids you can  
just remove the map stuff at the end

Hope it makes someone's life easier, like Aurelien's post made mine
