I basically followed the instructions from the below link EXACTLY and I'm getting this damn error? I have no idea what I'm supposed to do, wtf? Do I need to create some kind of persisted method?? There were several other questions like this and after reading ALL of them they were not helpful at ALL. Please help.

Omniauths Controller
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def google_oauth2
# You need to implement the method below in your model (e.g. app/models/user.rb)
@user = User.from_omniauth(request.env["omniauth.auth"])
if @user.persisted?
flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
sign_in_and_redirect @user, :event => :authentication
else
session["devise.google_data"] = request.env["omniauth.auth"].except(:extra) #Removing extra as it can overflow some session stores
redirect_to new_user_registration_url, alert: @user.errors.full_messages.join("\n")
end
end
end
User model code snippet
def self.from_omniauth(access_token)
data = access_token.info
user = User.where(:email => data["email"]).first
# Uncomment the section below if you want users to be created if they don't exist
# unless user
# user = User.create(name: data["name"],
# email: data["email"],
# password: Devise.friendly_token[0,20]
# )
# end
user
end
Changed the bottom portion to:
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
end
end
ran rails g migration AddOmniauthToUsers provider:string uid:string
Then it went to Successfully authenticated from Google account.
So I believe it works now. I think maybe the issue was I needed to add the provider and uid to the user database model?
