设计注册控制器的自定义操作无效资源 [英] custom action for devise registrations controller getting nil resource

问题描述

我已经更新了我的路线，指向我的新控制器继承来自Devise :: RegistrationsController。

我的路线.rb：

  devise_for：users，：controllers => {：registrations => registration} 
 
 devise_scope：user do 
 get/ users / password=> registrations＃change_password，：as => ：change_password 
 end 
  

我的registrations_controller.rb

  class RegistrationsController< Devise :: RegistrationsController 
 
 def change_password 
 end 
 
 end 
  

我的app / views / devise / registrations / change_password.html.erb

 <％= debug资源％GT; 
  

哪一个给我无。

什么我在这里错过吗？

谢谢！

解决方案

在Devise的内置 registrations_controller.rb ，有一个 authenticate_scope！方法创建您要查找的资源对象。它由 prepend_before_filter 执行，但仅适用于某些方法：

 类Devise ::注册控制器< DeviseController 
 ... 
 prepend_before_filter：authenticate_scope !,：only => [：edit，：update，：destroy]`
  

所以你只需要告诉你的自定义控制器在 change_password 方法上运行该过滤器：

  class RegistrationsController< Devise :: RegistrationsController 
 
 prepend_before_filter：authenticate_scope !,：only => [：change_password] 
 
 def change_password 
 end 
 
 end 
  

basically I want to have two separate actions for change password and change email instead of just one.

I have updated my routes to point to my new controller which inherits from Devise::RegistrationsController.

My routes.rb:

devise_for :users, :controllers => { :registrations => "registrations" }

devise_scope :user do
  get "/users/password" => "registrations#change_password", :as => :change_password
end

My registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController

  def change_password
  end

end

My app/views/devise/registrations/change_password.html.erb

<%=debug resource%>

Which gives me nil.

What am I missing here?

Thanks!

解决方案

In Devise's built-in registrations_controller.rb, there is an authenticate_scope! method that creates the resource object you're looking for. It is executed by a prepend_before_filter, but only for certain methods:

class Devise::RegistrationsController < DeviseController
  ...
  prepend_before_filter :authenticate_scope!, :only => [:edit, :update, :destroy]`

So you simply need to tell your custom controller to run that filter on your change_password method:

class RegistrationsController < Devise::RegistrationsController

  prepend_before_filter :authenticate_scope!, :only => [:change_password]

  def change_password
  end

end
