undefined local variable or method `password'

Error Message

undefined local variable or method `password' for #<Class:0x007f978068b9f0>

Extracted source (around line #52):

end

    def password.required?
        super && provider.blank?
    end

Explanation

I am following this tutorial on how to implement OmniAuth and copied his code exactly... I think. I have reached out to the the video owner and haven't heard back, and found this tutorial on his website and it looks like it was actually made in 2012, not 2015 like the YouTube video publish date shows. So, it may be possible that the code I am using is not compatible with the versions of Ruby, Rails or Devise that I have installed. (One of the reasons I was looking for a tutorial from this past year for implementing OmniAuth with Devise).

Question

Why is the error stating it is an undefined local variable when it is being defined at that line 52? It isn't used anywhere else in that file (User Model), but is elsewhere (login page and profile update page).

Versions Used

Ruby: ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]

Rails: Rails 4.2.0

Devise: 3.4.1

Code

The User Model:

## app/models/user.rb

01  class User < ActiveRecord::Base
02    
03      devise  :database_authenticatable, :registerable, :omniauthable,
04              :recoverable, :rememberable, :trackable, :validatable
05    
06      validates :birthday, :presence => true
07      validates :user_name, :presence => true, :uniqueness => { :case_sensitive => false }

The OmniAuth Callbacks Controller (I don't think this is part of the problem, but in case it is, or someone else needs the code):

## app/controllers/omniauth_callbacks_controller.rb

01  class OmniauthCallbacksController < Devise::OmniauthCallbacksController
02      
03      def all
04          user = User.from_omniauth(request.env["omniauth.auth"])
05          if user.persisted?
06              flash.notice = "You have been logged in."
07              sign_in_and_redirect user, :event => :authentication
08           else
09              session["devise.user_attributes"] = user.attributes
10               redirect_to new_user_registration_url
11           end
12      end
13    
14      alias_method :facebook, :all
15      alias_method :google, :all
16      alias_method :twitter, :all
17      alias_method :amazon, :all
18      alias_method :github, :all
19  end

Thank you in advance for your help.

Answer 1

You have a typo on line #52:

You should use:

def password_required?

instead of:

def password.required?
