how to check if current_user is logged in through omniauth?

If I have omniauth to allow users to log in using a provider such as facebook/twitter, how can I check to see if the current_user is logged in using omniauth?

I want to allow a code to run only if the current_user is logged in through omniauth.

Here's how my schema looks

create_table "users", :force => true do |t|
    t.string    "name"
    t.string    "email"
    t.timestamp "created_at",                         :null => false
    t.timestamp "updated_at",                         :null => false
    t.string    "password_digest"
    t.string    "remember_token"

  end

 create_table "authentications", :force => true do |t|
    t.integer  "user_id"
    t.string   "provider"
    t.string   "uid"
    t.datetime "created_at", :null => false
    t.datetime "updated_at", :null => false
    t.string   "secret"
    t.string   "token"
  end

Controller

    class PostsController < ApplicationController
    def create
      @post = current_user.posts.build(params[:post])

      if @post.save
        if @post.check
          UserMailer.check_email(@user).deliver
        else
          flash[:success] = "Posted"
          Twitter::Client.new.update(@post.content) if logged_using_omniauth? request != nil
        end
        redirect_to root_path
      else
        @feed_items = []
        render 'static_pages/home'
      end
    end

I would recommend to maintain a session to check if its logged in through omniauth.

in OmniauthCallbacksController

def method_name
 .......
 #if logged in set the session
 session[:logged_in_using_omniauth] = true
 .......
end

In ApplicationController

def logged_in_using_omniauth?
  session[:logged_in_using_omniauth].present?
end

And expose that method as helper method by:

helper_method :logged_in_using_omniauth?

Now use logged_in_using_omniauth? anywhere in controllers or views

You can verify it the following way:

def logged_using_omniauth? request
  res = nil
  omniauth = request.env["omniauth.auth"]
  res = Authentication.find_by_provider_and_uid ↵  
  (omniauth['provider'], omniauth['uid']) if omniauth
  res  
end

If the returned authentication is not nil then they logged in using omniauth.
