Ruby on Rails - 設計註冊鏈接不工作 - 未定義的方法`user_registration_path'

Question

此問題已被以前報告，但我仍然無法找到它的修復程序。

我已經在我的新RoR項目中安裝了插件Devise。當我點擊註冊鏈接上，我重定向到以下航線：

http://localhost:3000/users/registration/sign_up

不過，我得到以下錯誤：

undefined method `user_registration_path' for #<#<Class:0x007fd5d3503d58>:0x007fd5d3b0dcd0> 

提取的源（左右線＃5）：

2: <h1>Sign up</h1> 
3: </div> 
4: 
5: <%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %> 
6: <%= f.error_notification %> 
7: 
8: <div class="inputs"> 

我的路線產生如下：

new_user_session GET /users/sign_in(.:format)    devise/sessions#new 
     user_session POST /users/sign_in(.:format)    devise/sessions#create 
destroy_user_session GET /users/sign_out(.:format)    devise/sessions#destroy 
      password POST /users/password(.:format)    devise/passwords#create {:name_prefix=>:user} 
     new_password GET /users/password/new(.:format)   devise/passwords#new {:name_prefix=>:user} 
     edit_password GET /users/password/edit(.:format)  devise/passwords#edit {:name_prefix=>:user} 
        PUT /users/password(.:format)    devise/passwords#update {:name_prefix=>:user} 
        POST /users/registration(.:format)   devise/registrations#create {:name_prefix=>"user_registration"} 
       new GET /users/registration/sign_up(.:format) devise/registrations#new {:name_prefix=>"user_registration"} 
       edit GET /users/registration/edit(.:format) devise/registrations#edit {:name_prefix=>"user_registration"} 
        PUT /users/registration(.:format)   devise/registrations#update {:name_prefix=>"user_registration"} 
        DELETE /users/registration(.:format)   devise/registrations#destroy {:name_prefix=>"user_registration"} 
      home_index GET /home/index(.:format)     home#index 
       users GET /users(.:format)      users#index 
        POST /users(.:format)      users#create 
      new_user GET /users/new(.:format)     users#new 
      edit_user GET /users/:id/edit(.:format)    users#edit 
       user GET /users/:id(.:format)     users#show 
        PUT /users/:id(.:format)     users#update 
        DELETE /users/:id(.:format)     users#destroy 
       root  /         home#index 

我的routes.rb具有下面的代碼：

devise_for :users 

    get "home/index" 

    resources :users 
    root :to => "home#index"

創建此問題時，色器件的版本是1.1.0 RC和你運行Rails的3

請看就怎麼升級寶石色器件：

希望這有助於！

Answer 2

更新：我認爲你必須指定「方法」爲形式的「POST」。

5: <%= simple_form_for(resource, :as => resource_name, 
6: :url => registration_path(resource_name), 
7: :method => :POST) do |f| %> 

=====（以下棄用答案）

我認爲你必須在你的config/routes.rb中文件的問題。預期輸出是：

cancel_user_registration GET /users/cancel(.:format) devise/registrations#cancel 
     user_registration POST /users(.:format)   devise/registrations#create 
    new_user_registration GET /users/sign_up(.:format) devise/registrations#new 
    edit_user_registration GET /users/edit(.:format)  devise/registrations#edit 

所以一定要確保你的config/routes.rb中有這樣臨客代碼：

devise_for :users

試試這可能是幫助： 如果您提到任何設計寶石版本刪除，並只保留寶石「設計」，並在終端鍵入包更新命令。
