Saving user location, bio, website upon signup through Facebook - Omniauth Facebook

Question

Within my rails app, when someone signs up with Facebook, I'm trying to grab their email, name, image, location, bio, website.

I'm using Omniauth Facebook Here is the guide I followed.

The signup works smoothly, I get no errors in the browser or in my logs, but the location, bio, and website all come back as nill. What could be causing this? How can I fix this?

Am I allowed to call on user_location, user_about_me, user_website?

https://developers.facebook.com/docs/facebook-login/permissions/v2.2?locale=en_GB#reference

Gem file:

gem 'devise'
gem 'omniauth-facebook'

User.rb

  def self.from_omniauth(auth)
  where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
    user.email = auth.info.email
    user.password = Devise.friendly_token[0,20]
    user.name = auth.info.name  
    user.image = auth.info.image 
    user.location = auth.info.user_location 
    user.about = auth.info.user_about_me 
    user.website = auth.info.user_website 
  end
end

Devise.rb initializer

  config.omniauth :facebook, "APP_ID", "APP_SECRET",
          scope: 'email, user_location, user_about_me, user_website',
                  strategy_class: OmniAuth::Strategies::Facebook

Any help would be much appreciated!

Answer 1

The Facebook API documentation is rather confusing.

The problem is not with the rails code or the omniauth gem.

By default, Facebook only approves your application for grabbing a user's name, email, image, and a few other attributes.

To be able to grab any user's location, bio, or website, you need to individually apply for permission for each of these.
