Hello guys, I'm using sinatra/frankie/facebooker to prototype something simple to test the facebook api, i'm using mmangino-facebooker the more recent version from github and I cloned the most recent version of frankie. I'm using sinatra 0.9.6.
My main code is as simple as possible:
before do
ensure_application_is_installed_by_facebook_user @user = session[:facebook_session].user @photos = session[:facebook_session].get_photos(nil,@user.uid,nil) end
get "/" do erb :index end
get "/:uid/:image" do |uid,image|
@photo_selected = session[:facebook_session].get_photos([image.to_i],nil,nil)
erb :selected
end
The index page just renders a link to the other one (identified by regex "/:uid/:image") however I always get an error when it's trying to render the one identified by regex "/:uid/:image"

I've no idea why, it seems to be related with the auth token I guess..
I logged the request made o the fb rest server:
{:sig=>"4f244d1f510498f4efaae3c03d036a85", :generate_session_secret=>"0", :method=>"facebook.auth.getSession", :auth_token=>"9dae0d02c19c680b574c78d202b0582a", :api_key=>"70c14732815ace0ae71a561ea5eb38b7", :v=>"1.0"}
{:call_id=>"1269003766.05665", :sig=>"194469457d1424dc8ba0678979692363", :method=>"facebook.photos.get", :subj_id=>750401957, :session_key=>"2.lXL0z3s4_r573xzQwAiA9A__.3600.1269010800-750401957", :api_key=>"70c14732815ace0ae71a561ea5eb38b7", :v=>"1.0"}
{:sig=>"4f244d1f510498f4efaae3c03d036a85", :generate_session_secret=>"0", :method=>"facebook.auth.getSession", :auth_token=>"9dae0d02c19c680b574c78d202b0582a", :api_key=>"70c14732815ace0ae71a561ea5eb38b7", :v=>"1.0"}
The last one gives the error, it could be related with auth_token having the same value in the 1st and on the 3rd ?
Cheers and tks, Ze Maria
