Question

我正在尝试将控制器操作添加到另一个控制器操作中，因为我有一个列出一堆文件的索引页。在同一页面上，我有一个文件上传表，我想用Home #index controller方法调用文档#new controller＃method。我试过include，但它给了我一个未初始化的常量HomeController :: DocumentController错误。任何帮助表示赞赏。

class HomeController < ApplicationController


  def index

      if user_signed_in?
          #show folders shared by others
          @being_shared_folders = [] #current_user.shared_folders_by_others


         #show only root folders (which have no parent folders)
         @folders = current_user.folders.roots 

         #show only root files which has no "folder_id"
         @documents = current_user.documents.where("folder_id is NULL").order("name desc") 

         include DocumentController::new


        else
          redirect_to sign_up_index_path   
      end
   end

end



class DocumentsController < ApplicationController

  def new
      @document = current_user.documents.build    
      if params[:folder_id] #if we want to upload a file inside another folder
       @current_folder = current_user.folders.find(params[:folder_id])
       @document.folder_id = @current_folder.id
      end    
   end
end

您可以将操作存储在公共模块中，并将该模块包含在任何控制器所需的模块中：

# lib/common_actions.rb
module CommonActions
  def index
    # whatever
  end
end

# app.controllers/home_controller.rb
class HomeController < ApplicationController
  include CommonActions
end

# app.controllers/documents_controller.rb
class DocumentsController < ApplicationController
  include CommonActions
end

将控制器操作插入另一个控制器操作
