为设计添加客户操作

Question

我正在尝试将一个简单的自定义操作 cancelaccount 添加到由 devise 生成的用户模型中，但很难正确路由。

这是 route.rb 中的内容

devise_for :users, controllers: { registrations: "userregistrations", sessions: "sessions" } do        
  get '/users/:id/cancelaccount', to: 'userregistrations#cancelaccount', as: 'cancelaccount'   
end

这里是控制器

class UserregistrationsController < Devise::RegistrationsController      
  def create
  ...
  end

  def cancelaccount
      authenticate_user!
      Rails.logger.debug {"&& cancel"}
      @user = User.find(params[:id])
      unless (@user == current_user)
          redirect_to :back, :alert => "Access denied."
      end
  end
end

这是 HTML 中的 link_to 行：

<li><%= link_to "Cancel Account", {controller: "userregistrations", action: "cancelaccount", id: current_user.id} %></li>

这是我得到的错误：

没有路由匹配 {:action=>"cancelaccount", :controller=>"userregistrations", :id=>12}

如果我将 link_to 链接更改为：

<li><%= link_to "Cancel Account", cancelaccount_path(@user) %></li>

错误是：

# 的未定义方法 `cancelaccount_path'

非常感谢任何帮助。

这是“rake routes”的结果：

我不确定您的 devise_for 块有什么问题，但您可以轻松地将这条路线添加到它之外：

devise_for :users, controllers: { registrations: "userregistrations", sessions: "sessions" }
match '/users/:id/cancelaccount' => 'registrations#cancelaccount', via: 'get', as: 'cancelaccount'

这将添加你想要的路线：

cancelaccount GET    /users/:id/cancelaccount(.:format)                                       registrations#cancelaccount
