SessionsController＃中的Omniauth ArgumentError创建错误数量的参数（1表示2）Rails 4

Question

I am following an online tutorial to incorporate facebook omniauth to a sample application before adding it to my ROR application ( http://richonrails.com/articles/facebook-authentication-in-ruby-on-rails and https://coderwall.com/p/bsfitw ) but I am getting a wrong number of arguments error when I visit the "log into from facebook link".

ArgumentError in SessionsController#create wrong number of arguments (1 for 2). 

Here is my user model (straight from the tutorial) and where the error appears to be coming from, line 3 is highlighted as the source

class User < ActiveRecord::Base
 def self.from_omniauth(auth)
  where(auth.slice(:provider, :uid)).first_or_initialize.tap do |user|
    user.provider = auth.provider
    user.uid = auth.uid
    user.name = auth.info.name
    user.oauth_token = auth.credentials.token
    user.oauth_expires_at = Time.at(auth.credentials.expires_at)
    user.save!
  end
 end
end

SessionsController

class SessionsController < ApplicationController
 def create
    user = User.from_omniauth(env["omniauth.auth"])
    session[:user_id] = user.id
    redirect_to root_url
  end

 def destroy
    session[:user_id] = nil
    redirect_to root_url
  end
 end

I don't have the coffee script from the 2nd tutorial in there, I get a different error when I use it.

Any help would be greatly appreciated.
