New LinkedIn Permissions Problems (Rails omniauth-linkedin gem) - ruby-on-rails

Question

I'm using the omniauth-linkedin gem for my rails application:
https://github.com/skorks/omniauth-linkedin
It should be taking into account new LinkedIn permissions request procedures and scopes, but I am not having success obtaining either email addresses or full profiles (anything other than the default profile overviews).
Here is my omniauth.rb file:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'], :scope => 'r_fullprofile r_emailaddress'
end
The full profile and email address request are going through to LinkedIn initially, before the user enters her/his credentials. However, the scope requests are lost once the user signs in, and only the default profile overview information is accessible.
I think my problem has something to do with having to specifically request those fields within the scopes that I want, as is mentioned on the gem page (https://github.com/skorks/omniauth-linkedin). Still, I have tried adding specific field requests to my omniauth.rb file with no success (email field request below):
Rails.application.config.middleware.use OmniAuth::Builder do
provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'], :scope => 'r_fullprofile+r_emailaddress',
:fields => ["id", "email-address", "first-name", "last-name", "headline", "industry", "picture-url", "public-profile-url", "location", "positions", "educations"]
end
Apparently, I am supposed to request the default fields of the profile overview in addition to the non-default fields like email-address, positions, and educations in order to access these latter non-default fields.
LinkedIn email-address should be straightforward, as it is not a structured object like positions or educations are, and I believe I am missing code for specific fields within positions and educations that I want (not sure how i would write that and would love some input on that as well). I am using my new API keys, so I'm not sure what the problem may be. Do I need some kind of special permission from LinkedIn? Help is appreciated! Thank you.
Also, here is the relevant code for my auth controller:
require 'linkedin'
class AuthController < ApplicationController
def auth
client = LinkedIn::Client.new(ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'])
request_token = client.request_token(:oauth_callback =>
"http://#{request.host_with_port}/callback")
session[:rtoken] = request_token.token
session[:rsecret] = request_token.secret
redirect_to client.request_token.authorize_url
end
def callback
client = LinkedIn::Client.new(ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'])
if current_user.atoken.nil? && current_user.asecret.nil?
pin = params[:oauth_verifier]
atoken, asecret = client.authorize_from_request(session[:rtoken], session[:rsecret], pin)
current_user.atoken = atoken
current_user.asecret = asecret
current_user.uid = client.profile(:fields => ["id"]).id
flash.now[:success] = 'Signed in with LinkedIn.'
elsif current_user.atoken && current_user.asecret
client.authorize_from_access(current_user.atoken, current_user.asecret)
flash.now[:success] = 'Signed in with LinkedIn.'
end

Answer 1

Not sure if this is the most elegant solution, but this worked for me
I just added the config with the scope passed in the request_token_path
LINKEDIN_CONFIGURATION = { :site => 'https://api.linkedin.com',
:authorize_path => '/uas/oauth/authenticate',
:request_token_path =>'/uas/oauth/requestToken?scope=r_basicprofile+r_emailaddress+r_network+r_contactinfo',
:access_token_path => '/uas/oauth/accessToken' }
client = LinkedIn::Client.new(LINKEDIN_API_KEY, LINKEDIN_SECRET_KEY, LINKEDIN_CONFIGURATION )
and the rest of the code is the same.
Be sure to change the client constructor in the callback method as well.
