Authentication - nov/fb_graph GitHub Wiki
Assuming you successfully get user approval and facebook set auth cookie.
auth = FbGraph::Auth.new(CLIENT_ID, CLIENT_SECRET)
auth.from_cookie(cookies) # Put whole cookie object (a Hash) here.
auth.user.fetchYou shouldn’t need to update your Rails code for this migration.
What you need is update your Facebook Application Advanced Setting and JS SDK usage.
Step1: Enable “OAuth Migration” here.
https://developers.facebook.com/apps/:your_app_id/advanced
Step2: Set JS SDK’s FB.init “oauth” option true
FB.init({
appId: CLIENT_ID,
:
oauth: true
});Details here.

ps.
If you still have fb_sig_session_key, you can convert them to OAuth access tokens like below.
auth.fb_sig_session_key(YOUR_SESSION_KEY)auth = FbGraph::Auth.new(CLIENT_ID, CLIENT_SECRET)
auth.from_signed_request(params[:signed_request])
if auth.authorized?
# If authorized, the auth has user and access_token.
auth.user.fetch
else
# First time user, show "Connect" button here.
p auth.data
