我一直在关注Ryan Boland 的优秀 Rails 多租户教程，但遇到了 devise_invitable 的障碍。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) 上创建了一个新帐户和用户/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有任何当前会话。单击邀请链接后，我被重定向到登录页面 (mysubdomain.lvh.me:3000/users/sign_in) 并看到一个快速通知：“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，如此处所述。
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 hey@test.com - d1801fd8df78bd8cd125d5d8091fdc6a72c8f8faf4136cb282d497ec612195e9）。我已经确认这与接受请求时邀请查找的令牌匹配（请参阅下面的跟踪）。尽管如此，它仍会重定向到用户登录页面而不是完成注册，并且还会在跟踪日志中显示“过滤器链因 :resource_from_invitation_token 呈现或重定向而停止”。用户在此交易后最终仍未确认。
关于我在这里可能出了什么问题的任何想法？我在下面包括日志、我的应用程序控制器和我的设计配置......
这是邀请创建的跟踪日志：

这是我的 application_controller 很好的衡量标准......

这是我的设计初始化程序（config/initializers/devise.rb），我添加了“config.allow_insecure_token_lookup = true”行，看看这是否有帮助，但无济于事......
Devise.setup do |config|
config.mailer_sender = 'please-change-me-at-config-initializers-devise@example.com'
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
