remote:true选项不适用于rails 4中的文件字段 [英] remote: true option is not working with file field in rails 4

问题描述

我正在尝试使用remote:true选项通过Ajax提交表单，该选项包含输入字段以及文件字段(需要上传图片)

I am trying to submit form via ajax using remote:true option which contains input fields as well as file fields (need to upload images)

这是我的观点

= form_tag("/campaigns/upload_form", method: 'post', format: :js, enctype: 'multipart/form-data', remote: true) do

其中包含文件字段

= file_field :campaign, :fb_photo, class: 'form-control', id: 'fb_campaign_product_photo', title: 'Upload Image for your Product'

在控制器动作中

def upload_form
    # do some stuff
    respond_to do |format|
     format.html
     format.js
    end
  end

当我提交不带文件字段的表单时，它正在正确处理并呈现为JS

When I submit form without file field it is processing and rendering as JS correctly

Started POST "/campaigns/upload_form" for 127.0.0.1 at 2016-03-21 18:06:51 +0530
Processing by CampaignsController#upload_form as JS

但是当我尝试提交文件字段时，它正在作为HTML处理并抛出模板丢失错误，因为我没有为此添加视图.

but when I am trying to submit file fields, it is processing as HTML and throwing template missing error as I haven't added view for that.

编辑此帖子以告知: 我尝试了以下答案中建议的remotipart gem，它对我有用，但在浏览器控制台中仍然出现以下错误

Editing this post to tell that: I have tried remotipart gem as suggested in below answer and it worked for me but still getting following error in browser console

jquery.js?body=1:9665 POST http://localhost:3000/campaigns/upload_form 500 (Internal Server Error)

并在development.log中出现以下错误

and getting following error in development.log

 ActionView::MissingTemplate - Missing template campaigns/upload_form, application/upload_form with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :haml, :jbuilder]}. Searched in:

预先感谢

推荐答案

remote: true不适用于分段上传/文件上传.

remote: true does not work with multipart/file upload.

您可以为此使用远程宝石.
