我想使用我的Rails应用程序中出色的jQuery文件上传来上传多张图片。jQuery FileUpload gem未初始化
所以我也跟着Railscasts about it：
- 添加jquery-fileupload-rails gem
- 添加在我的application.js一个需要
- 创建形式为我的图片
- 初始化文件上传在一个名为“外壳文件.coffee“
但我不明白为什么什么事都没有发生n我尝试上传多张照片，使用拖放或点击“添加文件...”。
当我按下“提交”按钮时，每张照片都会正常保存。
请问，你能帮助我吗？我很困难。
非常感谢！
的application.js ```
//= require jquery
//= require jquery_ujs
//= require jquery-fileupload/basic
//= require housings
housings.coffee
$(document).ready(->
jQuery ->
file = $('fileupload').fileupload
console.log(file)
)
