After user accept to sign in with his facebook account, my app callback will

  • 0

After user accept to sign in with his facebook account, my app callback will be called by facebook, I’ve noticed that facebook didn’t retrieved user email, although in the configuration of omniauth, I’ve listed email in the permission list like this:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, omniauth_app_id, omniauth_app_secret_id,
           :scope => 'email,user_birthday,read_stream', :display => 'popup'
end

I am expecting to find email in request.env['omniauth.auth']['extra']['raw_info']['email'] or request.env['omniauth.auth']['info']['raw_info']['email']
But, its not there .. in fact, its not in any attribute within the request object!

Any idea ? is it related to my app facebook settings ?

EDIT

Here is the call back result from Facebook:

puts auth.inspect

#<OmniAuth::AuthHash credentials=#<Hashie::Mash expires=true expires_at=1353164400 token="***"> extra=#<Hashie::Mash raw_info=#<Hashie::Mash first_name="***" id="***" last_name="***" link="***" locale="ar_AR" name="***" timezone=2 updated_time="2012-11-17T13:01:59+0000" username="***" verified=true>> info=#<OmniAuth::AuthHash::InfoHash first_name="***" image="***" last_name="***" name="***" nickname="***" urls=#<Hashie::Mash Facebook="***"> verified=true> provider="facebook" uid="***">

I have replaced reall data with *, but, you can see that the email data is missing ..

EDIT2

Here is my gems used at Gemfile
gem ‘devise’

gem 'omniauth'
gem 'omniauth-facebook', '1.4.0'

gem 'oauth2'

    Ok, I found it! Here is what facebook says here

    By default, calling FB.login will attempt to authenticate the user
    with only the basic permissions. If you want one or more additional
    permissions, call FB.login with an option object, and set the scope
    parameter with a comma-separated list of the permissions you wish to
    request from the user.

    So, I have to add ’email’ like this:

     FB.login(function(response) {
   // handle the response
 }, {scope: 'email,user_likes'});

    Thanks very much for all people who tried to help 🙂
