jQuery FileUpload gem 未初始化

Question

我想在我的 Rails 应用程序中使用很棒的 jQuery 文件上传来上传多张照片。

所以我跟着Railscasts about it:

添加jquery-fileupload-rails gem
在我的 application.js
为我的照片创建一个表格
在名为 "housings.coffee"

但我不明白为什么当我尝试使用拖放或单击 "Add files..." 上传多张图片时没有任何反应。

当我按下 "submit" 按钮时，每张图片都正常保存。

拜托，你能帮帮我吗？我真的卡住了。

非常感谢！

application.js ```

//= require jquery
//= require jquery_ujs
//= require jquery-fileupload/basic
//= require housings

housings.coffee

$(document).ready( ->
  jQuery ->
    file = $('fileupload').fileupload
    console.log(file)
)

housings/_form.html.erb

<%= form_for [@user, @picture], html: { multipart: true, id: 'fileupload'} do |f| %>
      <!-- The fileupload-buttonbar contains buttons to add/delete files and start/cancel the upload -->
      <div class="row fileupload-buttonbar">
        <div class="span7">
          <!-- The fileinput-button span is used to style the file input field as button -->
          <span class="btn btn-success fileinput-button">
            <i class="icon-plus icon-white"></i>
            <span>Add files...</span>
            <%= f.file_field :image, multiple: true, name: 'picture[image]' %>
          </span>
            <%= f.hidden_field :housing_id, value: @housing.id %>
          <button type="submit" class="btn btn-primary start">
            <i class="icon-upload icon-white"></i>
            <span>Start upload</span>
          </button>
          <button type="reset" class="btn btn-warning cancel">
            <i class="icon-ban-circle icon-white"></i>
            <span>Cancel upload</span>
          </button>
          <!--<button type="button" class="btn btn-danger delete">-->
            <!--<i class="icon-trash icon-white"></i>-->
            <!--<span>Delete</span>-->
          <!--</button>-->
          <input type="checkbox" class="toggle">
        </div>
        <div class="span5">
          <!-- The global progress bar -->
          <div class="progress progress-success progress-striped active fade">
            <div class="bar" style="width:0%;"></div>
          </div>
        </div>
      </div>
      <!-- The loading indicator is shown during image processing -->
      <div class="fileupload-loading"></div>
      <br>
      <!-- The table listing the files available for upload/download -->
      <table class="table table-striped"><tbody class="files" data-toggle="modal-gallery" data-target="#modal-gallery"></tbody>
      </table>
  <% end %>

housings_controller.rb > index

@picture = Picture.new(housing_id: @user.housings.first.id)

不知道这是否可以帮助任何人，但我最终实现了另一个 javascript 工具，Dropzone。

我认为它会更好，因为 FileUpload 现在看起来很旧，我很头疼地试图让它工作。

Dropzone 与 Rails 完美配合，看起来很漂亮。作为参考，我遵循了this tutorial.
