I tried to ask this question - and did not find any help.
http://stackoverflow.com/questions/33493369/rails-devise-omniauth-problems-with-setup
I gave up trying to solve the problem and made a completely new application in which there was nothing else so that I could try to reduce the area of ​​influence of other errors.
In my new application, now I get an error message when I click on the link for new registration / new user.
I watched the rails by directing tutorials (having tried about 20 others) to get this setting. 1.5 years, and I'm still afraid.
The problem is how strategies are defined in the controller. I have 4 strategies (twitter, Facebook, google and linkedin), and currently I get a different error for each of them when I try to click the links to create a new registration with these accounts:
For Twitter: Unknown action Twitter action not found for Users: AuthenticationsController
For Facebook:
Given URL is not permitted by the Application configuration: One or more of the given URLs is not permitted by the App settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App domains.
This error is due to the fact that I can not find the documentation on Facebook. It shows how to use js to log in to Facebook, where I try to use gems in Rails. I am not worried about this error. I think this is due to the fact that my site is not defined as a local host, although I can not find anywhere except the callback URL in the Facebook developer console. My question is not related to this problem, I will find help to figure it out another time.
For LinkedIn:
Safari can't open the page "https://www.linkedin.com/uas/oauth2/authorization?client_id=LINKEDIN_DEV_ID&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fusers%2Fauth%2Flinkedin%2Fcallback&response_type=code&scope=r_basicprofile+r_emailaddress&state=3fef961c10410464cd5b0ca49b25112ce53fb65f1a3c794f".
Error: "Unable to decode raw data" (NSURLErrorDomain: -1015) I have an oauth2 callback defined as:
http://localhost:3000/users/auth/linkedin/callback
I don’t know what broke here.
For Google:
translation missing: en.devise.authentications.user.failure
The new registration form is simply updated when I click this link, and the error message says this above. I also do not know what causes this error.
Each of the errors is different.
I have a folder in my controllers folder called users. Inside, I have two controllers as follows:
Authentication Controller:
class Users::AuthenticationsController < Devise::OmniauthCallbacksController before_action :set_authentication, only: [:destroy] def index @authentications = current_user.authentications if current_user end def create omniauth = request.env["omniauth.auth"] authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid']) if authentication sign_in_and_redirect_user(:user, authentication.user.profile) elsif current_user current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid']) redirect_to user.profile_url else user = User.new user.omniauth(omniauth) if user.save! sign_in_and_redirect_user(:user, user.profile) else session[:omniauth] = omniauth.except('extra') redirect_to new_user_registration_url end end end def destroy @authentication.destroy respond_to do |format| format.html { redirect_to root_path } format.json { head :no_content } end end private # Use callbacks to share common setup or constraints between actions. def set_authentication @authentication = current_user.authentications.find(params[:id]) end
end
Registration Controller:
class Users::RegistrationsController < Devise::RegistrationsController #before_filter :check_permissions , :only => [ :new, :create, :cancel ] #skip_before_filter :require_no_authentication # before_action :configure_permitted_parameters, if: :devise_controller? def check_permissions authorize! :create, resource end def index if params[:approved] == "false" @users = User.find_all_by_approved(false) else @users = User.all end end def create super session[:omniauth] = nil unless @user.new_record? end # THIS IS A SUGGESTION FROM SITEPOINT TUTORIAL # protected # def configure_permitted_parameters # devise_parameter_sanitizer.for(:sign_up) << [:first_name, :last_name] # end private def user_params params.require(:user).permit(:first_name, :last_name, :email, :password ) end def build_resource(*args) super if session[:omniauth] @user.apply_omniauth(session[:omniauth]) @user.valid? end end end
User.rb has
devise :omniauthable, :omniauth_providers => [:facebook, :linkedin, :twitter, :google_oauth2 ] has_many :authentications, :dependent => :delete_all def apply_omniauth(omniauth) self.email = auth['extra']['raw_info']['email'] authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid'], :token => auth['credentials']['token']) end def password_required? (authentications.empty? || !password.blank?) && super end
On my .rb routes, I have:
devise_for :users, :controllers => { :registrations => "users/registrations", :omniauth_callbacks => "users/authentications"
In my omniauth.rb, I have:
require 'omniauth-facebook' require 'omniauth-google-oauth2' require 'omniauth-twitter' OmniAuth.config.logger = Rails.logger Rails.application.config.middleware.use OmniAuth::Builder do provider :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET'] end Rails.application.config.middleware.use OmniAuth::Builder do provider :facebook, ENV['FACEBOOK_ID'], ENV['FACEBOOK_KEY'], :scope => 'public_profile', info_fields: 'id,first_name,last_name,link,email', :display => 'popup', :client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}} end Rails.application.config.middleware.use OmniAuth::Builder do provider :google_oauth2, ENV['YT_CLIENT_ID'], ENV['YT_CLIENT_SECRET'], scope: 'profile', image_aspect_ratio: 'square', image_size: 48,
In my new registration / session sessions, I have:
<% if devise_mapping.omniauthable? %> <%= link_to icon('facebook', id: 'facebookauth'), user_omniauth_authorize_path(:facebook) %> <%= link_to icon('google', id: 'googleauth'), user_omniauth_authorize_path(:google_oauth2) %> <%= link_to icon('linkedin', id: 'linkedinauth'), user_omniauth_authorize_path(:linkedin) %> <%= link_to icon('twitter', id: 'twitterauth'), user_omniauth_authorize_path(:twitter) %> <% end %>
I think this is due to the fact that I did not call the strategy an authentication controller. In other tutorials, I set the following (now commented out from the controller, because the apply_omniauth method is now used).
Before completely disabling rail configuration, is there a way to specify the current structure for the named suppliers using the code that I already have?
OTHER ATTEMPT:
So, I quit RailsCast. I tried to follow this guide:
http://willschenk.com/setting-up-devise-with-twitter-and-facebook-and-other-omniauth-schemes-without-email-addresses/
I am confused by the link to add a new class called FormUser. I created a new model called form_user.rb and added the content as described. I am using Rails 4. I do not know what atto-accessor means, but I have this in my file as shown. I do not have an appropriate controller. I also do not have the associations defined in my user model (which, I think, this belongs to).
In any case, I followed the setup and now I get this error:
TypeError superclass mismatch for class OmniauthCallbacksController
The same is true for each of the strategies defined in my application.
Has anyone seen this particular error and any tips to fix it?
The only difference between my installation and the tutorial is that in my controllers I have a folder called users in which I have a registration controller and omniauth_callbacks controller. My routes have been set up to reflect this layer.
devise_for :users, class_name: 'FormUser', :controllers => { :registrations => "users/registrations",
