Devise + Omniauth:未定义的方法`user_omniauth_authorize_path’

我一直在关注facebook的omn​​iauth + devise集成指南,当我点击链接登录facebook链接时,我一直收到此错误。

user_omniauth_authorize_path #<#:0x000000035ea490>未定义方法user_omniauth_authorize_path #<#:0x000000035ea490>

我已经仔细检查了指南中的代码,我似乎无法弄清楚问题是什么。 我的gemfile:

 source 'https://rubygems.org' gem 'sendgrid' gem 'omniauth-facebook' gem 'gravatar' gem 'will_paginate' gem 'faker' gem 'devise' # Bundle edge Rails instead: gem 'rails', github: 'rails/rails' gem 'rails', '4.2.6' # Use postgresql as the database for Active Record gem 'pg', '~> 0.15' # Use SCSS for stylesheets gem 'sass-rails', '~> 5.0' # Use Uglifier as compressor for JavaScript assets gem 'uglifier', '>= 1.3.0' # Use CoffeeScript for .coffee assets and views gem 'coffee-rails', '~> 4.1.0' # See https://github.com/rails/execjs#readme for more supported runtimes # gem 'therubyracer', platforms: :ruby # Use jquery as the JavaScript library gem 'jquery-rails' # Turbolinks makes following links in your web application faster.

OmniauthCallbacksController:

 class Users::OmniauthCallbacksController  :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 

用户模型:

 class User  [: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 

尝试运行rake路由,看看omniauth的路径是什么。 我相信他们已经改变了最新版本的设计。 尝试改变

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

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

并看看它是否适合你。

显然omniauth路由的助手已经改变,因为我的rake routes命令返回了

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

而不是几个月前我开始这个项目的时候。

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

你也应该改变这条线

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

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

这对我有用,希望这有帮助。

它可能不是人们正在寻找的答案,但您可以随时在Gemfile中指定旧版本的devise gem。

gem 'devise', '~> 4.1.1'

这取消了我的生产网站,我不得不采取快速行动。 这很有效。
