ruby-on-rails - 尝试注册用户时未初始化的常量 OmniauthCallbacksController

Question

我在使用 OmniAuth 时遇到了问题。我一直在关注本教程 here尝试用我现有的应用程序实现它，但我想出了 ActionController::RoutingError at/users/auth/github/upgrade uninitialized constant OmniauthCallbacksController 错误。我看过其他几个 SO 帖子，但大多数答案都涉及拼写错误，并且我已经三次检查所有内容是否拼写正确。什么可能会干扰？

用户模型:

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
                 :recoverable, :rememberable, :trackable, :omniauthable

  has_many :identities

  def github
        identities.where( :provider => "github" ).first
    end

    def github_client
        @github_client ||= Github.client( access_token: github.accesstoken )
    end

    def linkedin
        identities.where( :provider => "linkedin" ).first
    end

    def linkedin_client
        @linkedin_client ||= Linkedin.client( access_token: linkedin.accesstoken )
    end
end

身份模型:

class Identity < ActiveRecord::Base
  belongs_to :user
  validates_presence_of :uid, :provider
  validates_uniqueness_of :uid, :scope => :provider

  def self.find_for_oauth(auth)
    identity = find_by(provider: auth.provider, uid: auth.uid)
    identity = create(uid: auth.uid, provider: auth.provider) if identity.nil?
    identity.accesstoken = auth.credentials.token
    identity.refreshtoken = auth.credentials.refresh_token
    identity.name = auth.info.name
    identity.email = auth.info.email
    identity.nickname = auth.info.nickname
    identity.image = auth.info.image
    identity.phone = auth.info.phone
    identity.urls = (auth.info.urls || "").to_json
    identity.save
    identity
  end
end

设计模型:

Devise.setup do |config|

  # config.omniauth :google_oauth2, ENV['GOOGLE_OAUTH2_APP_ID'], ENV['GOOGLE_OAUTH2_APP_SECRET'], scope: "email,profile,offline", prompt: "consent"
  config.omniauth :github, ENV['GITHUB_APP_ID'], ENV['GITHUB_APP_SECRET'], setup: true
  # config.omniauth :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_APP_SECRET'], scope: "email"
  config.omniauth :linkedin, ENV['LINKEDIN_APP_ID'], ENV['LINKEDIN_APP_SECRET'], setup: true

Omniauth 模型:

Rails.application.config.middleware.use OmniAuth::Builder do

  provider :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET']
  provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET']
end

表单用户模型

class FormUser < User
  attr_accessor :current_password

  validates_presence_of   :email, if: :email_required?
  validates_uniqueness_of :email, allow_blank: true, if: :email_changed?
  validates_format_of     :email, with: Devise.email_regexp, allow_blank: true, if: :email_changed?

  validates_presence_of     :password, if: :password_required?
  validates_confirmation_of :password, if: :password_required?
  validates_length_of       :password, within: Devise.password_length, allow_blank: true

  def password_required?
    return false if email.blank?
    !persisted? || !password.nil? || !password_confirmation.nil?
  end

  def email_required?
    true
  end
end

Omniauth 回调 Controller :

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def instagram
    generic_callback( 'instagram' )
  end

  def facebook
    generic_callback( 'facebook' )
  end

  def twitter
    generic_callback( 'twitter' )
  end

  def google_oauth2
    generic_callback( 'google_oauth2' )
  end

  def generic_callback( provider )
    @identity = Identity.find_for_oauth env["omniauth.auth"]

    # @user = @identity.user || current_user
    @user = @identity.user || User.find_by(email: @identity.email) || current_user
    if @user.nil?
      @user = User.create( email: @identity.email || "" )
      @identity.update_attribute( :user_id, @user.id )
    end

    if @user.email.blank? && @identity.email
      @user.update_attribute( :email, @identity.email)
    end

    if @user.persisted?
      @identity.update_attribute( :user_id, @user.id )
      # This is because we've created the user manually, and Device expects a
      # FormUser class (with the validations)
      @user = FormUser.find @user.id
      sign_in_and_redirect @user, event: :authentication
      set_flash_message(:notice, :success, kind: provider.capitalize) if is_navigational_format?
    else
      session["devise.#{provider}_data"] = env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end

  def upgrade
    scope = nil
    if params[:provider] == "google_oauth2"
      scope = "email,profile,offline,https://www.googleapis.com/auth/admin.directory.user"
    end

    redirect_to user_omniauth_authorize_path( params[:provider] ), flash: { scope: scope }
  end

  def setup
    request.env['omniauth.strategy'].options['scope'] = flash[:scope] || request.env['omniauth.strategy'].options['scope']
    render :text => "Setup complete.", :status => 404
  end
end

注册 Controller :

class Users::RegistrationsController < Devise::RegistrationsController
  def create

    unless params["user"]["code"] == ENV["CODE_TO_SIGN_UP"]
      respond_to do |format|
        format.html { return redirect_to new_user_registration_path, notice: 'The code you entered was wrong. Please contact ' + ENV["ADMIN_EMAIL"] }
      end
    end

    super
  end

  def update_resource(resource, params)
    if resource.encrypted_password.blank? # || params[:password].blank?
      resource.email = params[:email] if params[:email]
      if !params[:password].blank? && params[:password] == params[:password_confirmation]
        logger.info "Updating password"
        resource.password = params[:password]
        resource.save
      end
      if resource.valid?
        resource.update_without_password(params)
      end
    else
      resource.update_with_password(params)
    end
  end

路线

Rails.application.routes.draw do
devise_for :users, class_name: 'FormUser', :controllers => { 
    omniauth_callbacks: 'users/omniauth_callbacks',
    registrations: 'users/registrations'
  }

  devise_scope :user do
    get '/users/auth/:provider/upgrade' => 'omniauth_callbacks#upgrade', as: :user_omniauth_upgrade
    get '/users/auth/:provider/setup', :to => 'omniauth_callbacks#setup'
  end

end

如果您可能需要查看任何其他代码，请告诉我。感谢您的帮助，这让我发疯!

Answer 1

您在用户下将 OmniauthCallbacksController 命名为 Users::OmniauthCallbacksController，确保 Controller 路径是 your_app/app/controllers/users/omniauth_callbacks_controller‌ .rb 即，它位于 users 文件夹下。同样，您的 devise 路由应该类似于:

devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }

注意: users/omniauth_callbacks

更新

查看您共享的路由，您需要将 upgrade 和 setup 的路由更新为:

devise_scope :user do
    get '/users/auth/:provider/upgrade' => 'users/omniauth_callbacks#upgrade', as: :user_omniauth_upgrade
    get '/users/auth/:provider/setup', :to => 'users/omniauth_callbacks#setup'
  end

同样，注意 users/omniauth_callbacks
