为什么url helper在rails中放置"。"而不是" /"在路上?

标签: ruby-on-rails urlhelper

在我的应用中,我正致力于允许用户发送邀请。邀请函有令牌。在电子邮件中,我链接到路径中带有令牌的注册页面。在我使用的邮件控制器中:

new_user_registration_url(@invitation.token)

正如我看到瑞安贝茨所做的那样railscast。但它似乎输出了这种格式:

http://localhost:3000/signup.4a4aebcde29738a39c7f447f58817e49cf9b4cf4

为什么会有“。”而不是“/”?

更新

我正在使用设计,这里是相关的路线。我对这些并不自信;我曾经用它做过一点努力,但这些似乎有效:

  devise_scope :user do
    get '/signup/:invitation_token' => "registrations#new", :as => :new_user_registration
  end
  devise_for :users, :controllers => { :registrations => "registrations"}, :skip => [:registrations]
  as :user do
    get '/users/cancel' => 'devise/registrations#cancel', :as => :cancel_user_registration
    post '/users' => 'devise/registrations#create', :as => :user_registration
    get '/signup' => 'registrations#new', :as => :new_user_registration
    get '/users/edit' => 'devise/registrations#edit', :as => :edit_user_registration
    put '/users' => 'devise/registrations#update'
    delete '/users' => 'devise/registrations#destroy'
  end

Wihout routes.rb很难说,但作者似乎有类似的内容:

#in routes.rb
get 'signup' => 'controller#action', as: :new_user_registration

但必须:

get 'signup/:token' => 'controller#action', as: :new_user_registration

检查:

# in console
app.new_user_registration_path('ToKeN') # => "/signup/ToKeN"

如果你只是将字符串或符号作为参数传递给路径助手,我认为它被解释为format。尝试以下内容:

new_user_registration_url(:token => @invitation.token)

new_user_registration_url + "/" + @invitation.token
