未知操作：找不到 RegistrationsController 的操作“创建”？

Question

我决定制作一个 RegistrationsController，以便在用户注册时将其重定向到特定页面。唯一的问题是用户甚至没有被创建，因为我得到了错误：

Started POST "/users" for 127.0.0.1 at 2012-06-12 14:01:22 -0400

AbstractController::ActionNotFound (The action 'create' could not be found for R
egistrationsController):

我的路线和控制器：

devise_for :users, :controllers => { :registrations => "registrations" }
  devise_scope :user do
    get "/sign_up" => "devise/registrations#new"
    get "/login" => "devise/sessions#new"
    get "/log_out" => "devise/sessions#destroy"
    get "/account_settings" => "devise/registrations#edit"
    get "/forgot_password" => "devise/passwords#new", :as => :new_user_password
    get 'users', :to => 'pages#home', :as => :user_root
  end

class RegistrationsController < ApplicationController
  protected

  def after_sign_up_path_for(resource)
    redirect_to start_path
  end

  def create # tried it with this but no luck.

  end
end

这里发生了什么？这是如何解决的？

我将create 操作放在protected 之外，但现在我得到了Missing template registrations/create。删除操作让我回到Unknown action: create。

Answer 1

你的create方法是protected，这意味着它不能被路由到。

将您的 create 方法从您的 protected 方法中移出：

class RegistrationsController < ApplicationController

  def create

  end

  protected

  def after_sign_up_path_for(resource)
    redirect_to start_path
  end

end

Answer 2

看来问题出在您设置RegistrationsController 的方式上。如果您查看the Devise wiki page explaining how to do this，您会看到以下示例：

class RegistrationsController < Devise::RegistrationsController
  protected

  def after_sign_up_path_for(resource)
    '/an/example/path'
  end
end

请注意，RegistrationsController 继承自 Devise::RegistrationsController 而不是 ApplicationController。这样做是为了让您的自定义控制器继承 Devise 的所有正确行为，包括 create 操作。
