Wymuś + Omniauth: niezdefiniowana metoda "user_omniauth_authorize_path"

Question

Podążam za numerem omniauth + devise integration guide for facebook i ciągle pojawia się ten błąd, gdy kliknę link, aby zalogować się za pomocą linku do Facebooka.

metoda niezdefiniowany user_omniauth_authorize_path dla #<#<Class:0x0000000253a550>:0x000000035ea490>

ja dwukrotnie sprawdzane kodu w przewodniku i nie mogę wydawać się, aby dowiedzieć się na czym polega problem. Moja gemfile:

gem 'will_paginate' 
gem 'faker' 
gem 'devise'

group :development, :test do

    gem 'byebug' 
end

end 

OmniauthCallbacksController:

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController 



def facebook 

    @user = User.from_omniauth(request.env["omniauth"]) 

    if @user.persisted? 
     sign_in_and_redirect @user, :event => :authentication 
     set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format? 
    else 
     session["devise.facebook_data"] = request.env["omniauth.auth"] 
     redirect_to new_user_registration_url 
    end 
    end 

    def failure 
    redirect_to root_path 
    end 

end 

modelu użytkownika:

class User < ActiveRecord::Base 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable, 
     :omniauthable, :omniauth_providers => [:facebook] 

    has_many :likings, dependent: :destroy 
    has_many :comments, dependent: :destroy 
    has_many :posts, dependent: :destroy 
    has_many :active_relationships, class_name: "Relationship", 
            foreign_key: "follower_id", 
            dependent: :destroy 
    has_many :passive_relationships, class_name: "Relationship", 
            foreign_key: "followed_id", 
            dependent: :destroy 

    has_many :following, through: :active_relationships, source: :followed 
    has_many :followers, through: :passive_relationships, source: :follower 


    def feed 
    Post.where("user_id IN (?) OR user_id = ?", following_ids, id) 
    end 

    # follows user 
    def follow(other_user) 
    active_relationships.create(followed_id: other_user.id) 
    end 

    # unfollows user 
    def unfollow(other_user) 
    active_relationships.find_by(followed_id: other_user.id).destroy 
    end 

    def following?(other_user) 
    following.include?(other_user) 
    end 

    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] 
    end 
    end 
end 

Answer 1

Spróbuj uruchomić trasy natarcia i zobaczyć jakie są ścieżki dla omniauth. Uważam, że zmieniły się wraz z najnowszą wersją narzędzia. Spróbuj zmienić

<%= link_to "Sign in with Facebook", user_omniauth_authorize_path(:facebook) %> 

do

<%= link_to "Sign in with Facebook", user_facebook_omniauth_authorize_path %> 

i sprawdzić, czy to działa dla Ciebie.

Widocznie pomocnicy dla omniauth trasy uległy zmianie od trasy natarcia dowodzić mi zwrócone

user_facebook_omniauth_authorize GET|POST /users/auth/facebook(.:format)   omniauth_callbacks#passthru 

a nie jak to było kilka miesięcy temu, kiedy zacząłem projekt.

user_omniauth_authorize   GET|POST /users/auth/facebook(:provider)   omniauth_callbacks#passthru 

Należy również zmienić linię

@user = User.from_omniauth(request.env["omniauth"]) 

do

@user = User.from_omniauth(request.env["omniauth.auth"]) 

To co pracował dla mnie, mam nadzieję, że to pomaga.

Answer 2

To może nie być odpowiedź, której ludzie szukają, ale zawsze możesz podać starszą wersję gem'a w Gemfile.

gem 'devise', '~> 4.1.1'

ten zdjął mój zakład produkcyjny i musiałem działać szybko. To zadziałało.
