Rails is developing omniauth-facebook. return false

I spent the last day trying to fix this issue and it drove me crazy.

I had a facebook login last night that was working on my site and pulling basic user information. My problems started when I added :scope => 'user_birthday'

in config/initializers/omniauth.rb

, which now looks like

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, "APP_ID", "APP_SECRET", :scope => 'user_birthday'
end

      

        
        
        
      

    

For reference, I removed the line config.omniauth :facebook, "APP_ID", "APP_SECRET"

fromconfig/initializers/devise.rb

I spent hours trying to get this to work but in the end had to give up. Then this morning I ran again and it worked. Joyfully, I tried to add another parameter in :scope

, but now it's all broken again. I can get it to work if I delete :scope

, but when I put it back in, it fails every time (even if it's just :scope => 'user_birthday'

like I had my first lesson this morning).

To find the problem, I entered the debug code in omniauth_callbacks_controller.rb

and now it looks like this:

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    # You need to implement the method below in your model (e.g. app/models/user.rb)
        @user = User.from_omniauth(request.env["omniauth.auth"])
        puts "start before persist debug"
        puts @user.birthday
        puts @user.persisted?
        puts "end before persist debug"

    if @user.persisted?         
            puts "Start persisted debug"
            puts request.env["omniauth.auth"]
            puts "End debug"            
      sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
      set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
    else
      session["devise.facebook_data"] = request.env["omniauth.auth"]
            puts "Start unpersisted debug"
            puts request.env["omniauth.auth"]
            puts "End debug"
      redirect_to new_user_registration_url
    end
  end
end

      

        
        
        
      

    

This debug clearly shows that facebook is returning the information it needs, but the app fails because it .persisted?

returns false and so I am redirected to the new_user_registration page which returns the following: -

NoMethodError in Devise::Registrations#new
Showing /home/action/workspace/cloudapp/app/views/devise/shared/_links.html.erb where line #23 raised:

undefined method `omniauth_authorize_path' for #<#<Class:0x007f3aeffff038>:0x007f3aefffdf08>

      

        
        
        
      

    

I can't figure out for life why it .persisted?

returns false. I am using Nitrous.io for development with Heroku postgresql database. I confirmed that there are no users in the database by running

rails c
User.all

      

        
        
        
      

    

This returns:

  User Load (89.4ms)  SELECT "users".* FROM "users"                                                                                                                                                                                                     
=> #<ActiveRecord::Relation []> 

      

        
        
        
      

    

I have a feeling that the problem is models/user.rb

, but I can't figure out how to debug it to see if it finds the user and therefore won't continue, or tries to create it and won't work. Does anyone know an easy way to debug this?

def self.from_omniauth(auth)        
      where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
        user.email = auth.info.email
        user.password = Devise.friendly_token[0,20]
        user.name = auth.info.name   # assuming the user model has a name
        user.birthday = auth.extra.raw_info.birthday
        # user.image = auth.info.image # assuming the user model has an image
    end
end

      

        
        
        
      

    

I walked around 50 times and was close to giving up.

The only thing I can think of is something that where(provider: auth.provider, uid: auth.uid)

returns something (which shouldn't, because my database is empty). Maybe there is an index that exists somewhere outside my database and what is it looking for?

Please, for my sanity, can anyone help? If you need more information, I will gladly provide it

Edit 1

Just tried the following and it works, which makes me more confusing than ever:

• Delete the app from my facebook account when I test this account.
• Try to login to facebook from the :scope => 'user_birthday'
  
  left. Facebook lists the permissions requested as your public profile and birthday
  
  . Accept and submit back to my site that does not match the above (even if the information is definitely sent back).
• Please uninstall :scope => 'user_birthday'
  
  and try to login again using facebook. Access facebook which lists the permissions requested as your public profile and email address
  
  . Accept and get directed back to the site that is now up and running, and also have the user's birthday that was available and accessible because I had the resolution with facebook from number 2. above.

Now I'm completely at a loss
