ruby-on-rails - How to grab and display a twitter users followers list using twitter api - Ruby on Rails / omniauth-twitter

Question

I have successfully integrated my application with omniauth and my twitter account. I was able to grab the name, provider, uID, location, avatar and URL for each user that logs in.

But when I try to grab a list of the users followers I am not able to. I have tried using this documentation https://github.com/arunagw/omniauth-twitter#authentication-hash

my User.rb

class User < ApplicationRecord
  class << self
  def from_omniauth(auth_hash)
    user = find_or_create_by(uid: auth_hash['uid'], provider: auth_hash['provider'])
    user.name = auth_hash['info']['name']
    user.location = auth_hash['info']['location']
    user.image_url = auth_hash['info']['image']
    user.url = auth_hash['info']['urls']['Twitter']
    user.save!
    user
  end
end
end

I tried adding this to my user.rb unsuccessfully

 # user.followers = auth_hash['extra']['raw_info']['followers_count']

in my index.html.erb

<% if current_user %>
  <div class="page-header">
    <h1 class="">Here is some info about you...</h1>
  </div>
  <div class="panel panel-default">
    <div class="panel-body">
      <ul>
        <span><strong>Name:</strong> <%= current_user.name %></span><br>
        <span><strong>Provider:</strong> <%= current_user.provider %></span>
        <li><strong>uID:</strong> <%= current_user.uid %></li>
        <li><strong>Location:</strong> <%= current_user.location %></li>
        <li><strong>Avatar URL:</strong> <%= image_tag current_user.image_url, alt: current_user.name %></li>
        <li><strong>URL:</strong> <%= current_user.url %></li>
        **<li><strong>Followers:</strong> <%= current_user.followers_count %></li>**
      </ul>
    </div>
  </div>
<% else %>
  <div class="jumbotron">
  <h1 class="text-center">Welcome!</h1>
  <p>Authenticate via twitter to get started.</p>
</div>
<% end %>

Ive tried first taking the Followers_count as-well just for testing but was unable to.

Any insights on how I should proceed? or what I should add to my users model?

schema.rb

  create_table "users", force: :cascade do |t|
    t.string "provider", null: false
    t.string "uid", null: false
    t.string "name"
    t.string "location"
    t.string "image_url"
    t.string "url"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.string "followers_count"
  end

end
