Devise + Omniauth：未定义的方法`user_omniauth_authorize_path' [英] Devise + Omniauth: undefined method `user_omniauth_authorize_path'

问题描述

我一直在追踪 omniauth + devise整合指南当我点击链接使用Facebook链接登录时，我会收到此错误。

I've been following the omniauth + devise integration guide for facebook and I keep getting this error when I click the link to sign in with facebook link.

未定义的方法 user_omniauth_authorize_path for ＃<＃< Class：0x0000000253a550>：0x000000035ea490> ;

undefined method user_omniauth_authorize_path for #<#<Class:0x0000000253a550>: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。我的宝石文件：

I've double checked the code in the guide and I can't seem to figure out what the issue is. My gemfile:

OmniauthCallbacksController：

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

用户模型：

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

推荐答案

尝试运行rake路线，看看omniauth的路径。我相信他们已经改变了最新版本的设计。
尝试更改

Try running rake routes and see what the paths for omniauth are. I believe they have changed with the most recent release of devise. Try changing

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

至

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

，看看是否适用于您。

显然，对于我的rake路线命令，omniauth路线的帮助者已经改变了

Apparently the helpers for the omniauth routes have changed since the rake routes command for me returned

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

而不是几个月前，当我开始该项目。

and not as it was some months ago when I started the project.

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

您还应该更改行

@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。

This is what worked for me, hope this helps.
