devise_invitable，删除待处理的邀请

Question

我有一个 Rails 应用程序，其中Users 可以邀请Members 到Teams，为此我尝试使用 gem devise_invitable。到目前为止它运行良好，但在删除待处理的邀请时遇到了一些问题。例如，如果用户输入了错误的电子邮件地址，我希望他/她能够删除邀请。但我无法让它工作。我的路线是这样设置的：

devise_for :users, :controllers => {sessions: "users/sessions", registrations: "users/registrations", invitations: "users/invitations"}

resources :teams do
  resources :invitations
  [...]

我的自定义"users/invitations"（放置在controllers/users/invitations_controller.rb）控制器的相关部分如下所示：

class Users::InvitationsController < Devise::InvitationsController

  before_action :set_invitation, only: [:destroy]

  def destroy
    This currently never gets called
    team = @invitation.team
    @invitation.destroy
    respond_to do |format|
      format.html { redirect_to edit_team_path(team) }
      format.json { head :no_content }
    end
  end

我尝试像这样链接destroy 操作：

= link_to team_invitation_path(@team, invitation), method: :delete, data: { confirm: 'Are you sure you want to delete this invitation?'}, class: "label label-danger label-pill pull-xs-right" do
  = icon("trash-o")

我的Invitation 模型如下所示：

class Invitation < ActiveRecord::Base

  belongs_to :member
  belongs_to :team
  validates_presence_of :recipient_email
  enum status: [ :pending, :accepted ]

end

当我点击链接时，我目前收到以下错误：

Routing Error
uninitialized constant InvitationsController

我不完全确定如何解决它或我可能错过了什么。 devise_invitable 不是 100% 适合我现在需要的宝石。

有什么想法可以让它发挥作用吗？

我跑完rake routes后的相关路线：

# These were here before as well
accept_user_invitation GET    /users/invitation/accept(.:format)

user_invitation POST   /users/invitation(.:format)                                                                                 users/invitations#create
new_user_invitation GET    /users/invitation/new(.:format)                                                                             users/invitations#new

# My custom / new team invitation routes
team_invitations 
GET    /teams/:team_id/invitations(.:format)                                                                        users/invitations#index 
POST    /teams/:team_id/invitations(.:format)                                                                        users/invitations#create new_team_invitation 
GET    /teams/:team_id/invitations/new(.:format)                                                                      users/invitations#new edit_team_invitation 
GET    /teams/:team_id/invitations/:id/edit(.:format)                                                                 users/invitations#edit team_invitation 
GET    /teams/:team_id/invitations/:id(.:format)                                                                     users/invitations#show 
PATCH  /teams/:team_id/invitations/:id(.:format)                                                                     users/invitations#update 
PUT    /teams/:team_id/invitations/:id(.:format)                                                                    users/invitations#update 
DELETE /teams/:team_id/invitations/:id(.:format)                                                                  users/invitations#destroy

新路线指向例如users/invitations#destroy

Answer 1

我假设您试图指向Users::InvitationsController，它与InvitationsController 不同——后者不存在。您需要将此通知routes.rb：

resources :teams do
  resources :invitations, module: 'users'
    ...
  end
end
