Question

如何在rails app中创建文件夹，以及如何插入文件夹选项。

喜欢：使用鼠标打开，新建，重命名，删除。（例如：windows）

但我正在使用它创建一个新的folder.how来创建正确的方法。

html.erb

  <%@folder.order("folder_name ASC").each do|i|%>

  <div class="col-md-2">

  <i class="fa fa-folder fa-1x" aria-hidden="true"></i>&nbsp;<%=link_to i.folder_name,users_image_browse_path(i)%>

  </div>

  <%end%>

  <a style="width: 12%;" class="btn btn-block btn btn-success hvr-sweep-to-right" data-toggle="modal" data-target="#applyModal"><i class="fa fa-plus "></i> Create Folder</a>

这是我创建文件夹的脚本。

  <div class="modal fade" id="applyModal" tabindex="-1" role="dialog" aria-labelledby="applyModalLabel" aria-hidden="true">

    <div class="modal-dialog modal-dialog_2">

      <div class="modal-content" style="margin-top: 180px;">

        <div class="modal-header">

          <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true"></span></button>

          <h4 class="modal-title" id="myModalLabel">

            <div class="head_4">

              <div style="font-size: 47%; font-family: times;">Create New Folder</div>

            </div>

          </h4>

        </div>

       <div class="modal-body">

        <%= form_for Folder.new,:url=>{:controller=>"users",:action=>"create_folder"} do |i|%>

          <div class="section">

            <%= i.label :folder_name,:style=>"font-family: t;"%>

            <%= i.text_field :folder_name,:value=>"New Folder",:class=>"form-control",:autofocuse=>true ,required:true%>

          </div>

          <div class="section" align="center">

            <%= i.submit "Save" ,:class=>"btn btn-info"%>

          </div>

       <%end%>

       </div>

      </div>

    </div>

  </div>

Controller.rb

def new_folder
 @folder=Folder.new
end

def create_folder
  @folder=Folder.new(folder_params)
  @folder.update(:project_id=>$p_id,:parent_folder_id=>$f_id)
  if @folder.save
    redirect_to :action=>"image_browse"
  else
    render "image_browse"
  end
 end

应用程序/型号/ folder.rb

  class Folder
   include Mongoid::Document
   field :folder_name, type: String
   field :parent_folder_id, type: String
  field :project_id, type: String
 end

执行此操作：

def create_folder
@folder= params[:folder][:name]
Dir.mkdir @folder
end

对于嵌套目录执行此操作：

def create_folder
@folder= params[:folder][:name]
require 'fileutils'
FileUtils::mkdir_p @folder
end
