Rails 4 devise_invitable 邀请令牌无效

我一直在关注Ryan Boland 的优秀 Rails 多租户教程 https://www.youtube.com/watch?v=nXqwFEjxyhM，但遇到了 devise_invitable 的问题。我在用...

Rails 4.1.5 
devise 3.3.0  
devise_invitable 1.3.6
Postgresql

我在选定的子域 (mysubdomain.lvh.me:3000) 上创建一个新帐户和用户/帐户所有者，我可以从中发送用户邀请。我在隐身 Chrome 会话中打开邀请链接，以确保我没有登录或没有任何当前会话。单击邀请链接后，我将被重定向到登录页面 (mysubdomain.lvh.me:3000/users/sign_in) 并看到一条闪烁通知：“提供的邀请令牌无效！”

我正在使用一个非常简单的邮件程序视图（app/views/devise/mailer/invitation_instructions.html.erb）...

<%= link_to 'Accept invitation', accept_invitation_url(@resource, :invitation_token => @token) %>

如您所见，我确保使用@token，如所述here https://github.com/scambra/devise_invitable/issues/410.

创建邀请后，我已确认邀请令牌已保存到数据库中（在本例中为[电子邮件受保护] /cdn-cgi/l/email-protection- d1801fd8df78bd8cd125d5d8091fdc6a72c8f8faf4136cb282d497ec612195e9）。我已确认这与接受请求时查找邀请时的令牌相匹配（请参阅下面的跟踪）。尽管如此，它仍然重定向到用户登录页面而不是完成注册，并且还在跟踪日志中显示“过滤器链因：resource_from_invitation_token 呈现或重定向而停止”。此笔交易后，用户最终仍处于未确认状态。

关于我这里可能出什么问题有什么想法吗？我在下面包括日志、我的应用程序控制器和我的设备配置...

以下是邀请创建的跟踪日志：

这是我的 application_controller 的良好措施......

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
  before_filter :load_schema, :authenticate_user!, :set_mailer_host
  before_filter :configure_permitted_parameters, if: :devise_controller?


  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:first_name, :last_name, :company, :email, :password, :password_confirmation, :remember_me, :image, :image_cache)}
    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:first_name, :last_name, :company, :email, :password_confirmation, :current_password, :image, :image_cache)}
  end

private
  def load_schema
    Apartment::Database.switch('public')
    return unless request.subdomain.present?

    if current_account
      Apartment::Database.switch(current_account.subdomain)
    else
      redirect_to root_url(subdomain: false)
    end
  end  

  def current_account
    @current_account ||= Account.find_by(subdomain: request.subdomain)
  end
  helper_method :current_account

  def set_mailer_host
    subdomain = current_account ? "#{current_account.subdomain}." : ""
    ActionMailer::Base.default_url_options[:host] = "#{subdomain}lvh.me:3000"
  end

  def after_sign_out_path_for(resource_or_scope)
    new_user_session_path
  end

  def after_invite_path_for(resource)
    users_path
  end

end

这是我的 Devise 初始化程序（config/initializers/devise.rb），我添加了“config.allow_insecure_token_lookup = true”行来查看这是否有帮助，但无济于事......

Devise.setup do |config|

  config.mailer_sender = '[email protected] /cdn-cgi/l/email-protection'

  require 'devise/orm/active_record'

  config.case_insensitive_keys = [ :email ]

  config.strip_whitespace_keys = [ :email ]

  config.skip_session_storage = [:http_auth]

  config.stretches = Rails.env.test? ? 1 : 10

  config.reconfirmable = true

  config.expire_all_remember_me_on_sign_out = true

  config.password_length = 8..128

  config.sign_out_via = :delete

  config.allow_insecure_token_lookup = true
end

我更愿意发表评论，但我只有 36 分并且不允许，所以这里是一个不完整的答案：

这是来自 devise_invitable InvitationsController 的代码，它正在重定向您的请求

def resource_from_invitation_token
  unless params[:invitation_token] && self.resource = resource_class.find_by_invitation_token(params[:invitation_token], true)
    set_flash_message(:alert, :invitation_token_invalid)
    redirect_to after_sign_out_path_for(resource_name)
  end
end

在你的 Rails 控制台中尝试运行：

token = '3GXDmi7NntDRdhvo57q5' #the token sent in the invitation email
User.find_by_invitation_token(token, true)

看看是否会返回您的用户。可能不会，但也许这会让您更接近答案。但愿如此。
