devise token auth + Save Facebook auth_hash info in database

[gustavoguimaraes]

I am using Devise auth token gem and ng-token auth for authenticating my single page app. Besides registering with email there is the option to sign-up via Facebook. It works.

My problem is that as for my Fb request scope I set to get the user_friends, email and public_info, however when I get the request I don't see the auth_hash request.env['omniauth.auth']. This is described in the omniauth-facebook gem documentation.

Basically I want to save what FB gives back about the user in my database. How would you do it?

👍 I am having the same issue

According to the devise wiki on omniauth, it expects the response to have request.env['omniauth.auth'] which I can't find.

Instead I have in my response request.env['action_dispatch.request.unsigned_session_cookie'] which does not give me all the info that is supposed to be in auth_hash scope I set more on auth_hash info here https://github.com/mkdynamic/omniauth-facebook#auth-hash.

If you want to see the response, you can override the OmniauthCallbackController as described here and in the omniauth_success action, use a debugger. request.env['omniauth.auth'] returns nil. @lynndylanhurley Do you know why? Any guidance for anyone trying to solve this? Thanks you very much for creating these amazing libraries!

@gustavoguimaraes I could only find information in the auth_hash but when I change the scope it will not return new data. It seems as though the scope values are not getting passed correctly.

@tylerbobella totally.

Within request.env['action_dispatch.request.unsigned_session_cookie']

I see
... {"provider"=>"facebook", "uid"=>"******", "info"=>{"name"=>"John Doe", "image"=>"http://graph.facebook.com/99999/picture"}, .....

but no other info from public_profile or scopes values

@gustavoguimaraes I'm running into the same problem – I'm especially missing the email attribute in the info hash. Did you find a solution?

@gustavoguimaraes I was able to resolve this issue by adding the desired fields to the provider hash:

# /config/initializers/omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
  provider(
    :facebook,
    ENV['FACEBOOK_KEY'],
    ENV['FACEBOOK_SECRET'],
    scope: 'email',
    info_fields: 'email,first_name,last_name')
end

Now omniauth-facebook actually requests (and receives) email, first_name, last_name and passes it forward to the DeviseTokenAuth::OmniauthCallbacksController (make sure to define your own if you want to use first_name,last_name etc.).

Closing this issue since it's somewhat out of scope for this gem and a configuration example for omniauth-facebook has been provided. Can re-open if need be though.
