ruby-on-rails-3 - 设计 gem 和自定义控制器

Question

我有一个为 Devise 创建的控制器，我想用它在 /devise/registration/ 中添加更多页面

class RegistrationsController < Devise::RegistrationsController
  skip_before_filter :detect_account_ended

  def import
    @title = "Import customers from Quickbooks"
  end

  def categories
    @title = "Edit Categories"
    @categories = current_user.categories

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @categories }
    end
  end

  protected

    def after_update_path_for(resource)
      edit_user_registration_path
    end
end

我创建了路线

  devise_for :users, 
    :path_names => { 
      :sign_up => "register", 
      :destroy => "logout" },
    :controllers => { 
      :registrations => :registrations } do
        get '/users/sign_out' => 'devise/sessions#destroy'
        get '/users/import' => 'devise/registrations#import'
        get '/users/categories' => 'devise/registrations#categories'
  end

和意见。视图正确显示，但我从注册控制器传递的对象不会进入视图。我该如何解决这个问题，以便将这些对象传递给我的视图？

尝试像这样直接访问它们：

current_user.categories

在视图中也可用，至于current_user@title，您不必将其作为变量传递，因为您也可以将所需的文本直接添加到视图中。
