Omniauth facebook - Authentication Fields

Question

I am trying to configure omniauth for a website to login via facebook. The problem is that facebook is not sending the "info" field.

I have 2 facebook apps for different conditions.

For one application, the answer has fields

#<OmniAuth::AuthHash credentials=#<OmniAuth::AuthHash expires=true expires_at=14 42913734 token="CAAU6NSaozowBANJoDeZCakDuUZAiIZBGQ5cmFYRTwQwo7SK2JK7uhcRK7WIadpp zjKfict9pMASS2k9XJZBTgnI8WJvJA42er9Xj8nuoeLjbEQo8TKB7b5hVlsOwRs5kcPpOPwyUTUc0ekF uu2w4ubNZBMXZBw5xjGkQwZBZA46fATGOvDXJSrWOOAiQteWnkSO9JkeZC2SfmZCQqcSR0zdV52"> ex tra=#<OmniAuth::AuthHash raw_info=#<OmniAuth::AuthHash id="xxxxxxxxxx" na me="xxxxxxx">> info=#<OmniAuth::AuthHash::InfoHash image="http://graph.facebo ok.com/xxxxxxxxxxx/picture" name="xxxx"> provider="facebook" uid="xxxxxxxx"> 

In env development, I get an answer

I wonder if this is an application level setting because the code is the same for both. Only the difference on the application side is API v2.3 and the other 2.4.

Answer 1

There is a difference when you use v2.3 and v2.4.

In your config/initializers/devise.rb or wherever you put your API key, you need to add info_fields except scope ,

Example

 config.omniauth :facebook, APP["facebook_id"], APP["facebook_secret"], :scope => 'email,public_profile', info_fields: 'email,name'
