我的设计在几天前运作良好。 似乎在发送电子邮件之前某些参数丢失了： 这是堆栈跟踪，它确认设计正在将电子邮件保存在数据库中：

我试图弄清楚错误隐藏的地方，但我很确定它是设计的默认配置。 奇怪的是，我的浏览器显示电子邮件不再是参数的一部分：
Request
Parameters:
{"utf8"=>"✓",
"authenticity_token"=>"9Cj9YYy7gPbVbplSAHs+a3DkUxAYU00oMJUG11dIMAI=",
"athlete"=>{},
"commit"=>"Send an invitation"}
不知道是否有任何帮助，但我也在发布我的路线：
App::Application.routes.draw do
root :to => 'home#index'
# Devise for admins and athletes but no registration possible
# without an invitation
devise_for :admins do
get 'admins/edit' => 'devise/registrations#edit', :as => 'edit_admins_registration'
put 'admins' => 'devise/registrations#update', :as => 'admin_registration'
end
devise_for :athletes, :except => :invitable do
get 'athletes/edit' => 'devise/registrations#edit', :as => 'edit_athletes_registration'
put 'athletes' => 'devise/registrations#update', :as => 'athlete_registration'
end
# Common ressource url for both athletes and admins
# events are nested for athletes (note: athlete --hasmany--> events)
resources :athletes do
resources :events, :only => [:index, :show]
resources :attachments, :only => [:create, :index, :new, :destroy]
post 'exportcal' => 'athletes#exportcal'
end
resources :admins
end

同样的事发生在我身上。这里讨论并解决了这个问题：
https://github.com/scambra/devise_invitable/issues/265
我的解决方案：
gem 'devise'
gem 'devise_invitable', :git => "git://github.com/scambra/devise_invitable.git", :branch => 'master'
目前给我的是：
Using devise (2.2.1)
Using devise_invitable (1.1.4) from git://github.com/scambra/devise_invitable.git (at master)
