i have problem on production facebook login happened today. i'm using rails omniouth-facebook gem authentication users via fb.
so, after debugging figure out uid got in response facebook isn't same uid particular user has stored in database.
i have part:
find_by(provider: auth.provider, uid: auth.uid) where auth env['omniauth.auth'] , when manually check user auth.email in database uids not matched, function returns nil , login failure.
does has idea problem? appreciate hint.
thanks, bojan
with api v2.0, facebook introduced app-scoped user ids.
for every new user logs in app after switch made 2.0, not “global” user id more, app-scoped one, unique app - more specific, tied app id.
so if using different app ids, resp. switched app ids @ point, of course different app-scoped ids same user.
if have business has several apps, can connect them via business manager, can connect different app-scoped user ids different apps.
