我试图获得omniauth-facebook并在我的用户模型中设计彼此jive。当我运行$ rails s时，我收到错误

来自user.rb的来源：
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :omniauthable, :omniauth_providers => [:facebook]
has_one :contact_info
has_and_belongs_to_many :channels
has_and_belongs_to_many :regions
has_and_belongs_to_many :roles
has_many :managed_campaigns, class_name: Campaign, foreign_key: :owner_id
accepts_nested_attributes_for :contact_info
validates_associated :contact_info, message: "is not complete"
delegate :full_name, to: :contact_info
def facebook
@user = User.find_for_facebook_oauth(request.env["omniauth.auth"])
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
def self.find_for_facebook_oauth(auth)
where(auth.slice(:provider, :uid)).first_or_create do |user|
user.provider = auth.provider
user.uid = auth.uid
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
user.name = auth.info.name
user.image = auth.info.image
end
end
end
我没有看到语法中缺少的结尾，虽然我完全承认我对这种语言很新，如果我这样做会感到惊讶。我系统地评论了源的每个部分，以及所有现有的结尾（并在最后添加了额外的部分）。唯一有用的是评论`def facebook＆＃39;到最后。一位朋友建议检查我的routes.rb文件，但我再也不熟悉语法，以辨别是否存在问题。 routes.rb如下：
VitalApp::Application.routes.draw do
devise_for：user，has_one :: contact_info＃,: controllers =＆gt; {：omniauth_callbacks =＆gt; ＆＃34;用户/ omniauth_callbacks＆＃34; } devise_scope：用户做 得到＆＃34;注册＆＃34;，到：＆＃34;设计/注册#new＆＃34; 得到＆＃34;登录＆＃34;，到：＆＃34;设计/会话#new＆＃34; delete＆＃34; logout＆＃34;，to：＆＃34; devise / sessions＃destroy＆＃34; 结束 root＆＃34; home #index＆＃34; 资源：活动 端
非常感谢任何见解！
