我遇到让OmniAuth工作的问题。我一直在关注本教程here尝试使用现有应用实现它，但我想出了ActionController::RoutingError at /users/auth/github/upgrade uninitialized constant OmniauthCallbacksController错误。我已经查看了其他几篇SO帖子，但大多数答案都涉及拼写错误，而且我已经三重检查了所有内容拼写正确。什么可能干扰？
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
FormUser Model
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 Callbacks 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
注册控制器：
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 => {

}
devise_scope :user do

答案 0 :(得分：3)
您在用户下将OmniauthCallbacksController命名为Users::OmniauthCallbacksController，确保控制器路径为your_app/app/controllers/users/omniauth_callbacks_controller.rb，即它位于users文件夹下。同样，您的devise路线应如下所示：
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
注意： users/omniauth_callbacks
<强>更新
查看您分享的路线，您需要更新upgrade和setup的路线：
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
再次，注意： users/omniauth_callbacks
