异步 jQuery 上传似乎仍然在向 Heroku 上传一些东西
Asynchronous jQuery Upload Still Seems to Upload Something to Heroku
我在 Heroku 上有一个相当简单的 Rails 应用程序 运行，最终用户可以在其中上传两张照片并通过电子邮件和短信接收 link 照片。
该应用程序最初是实时 运行 Paperclip，但由于 Heroku 的 30 秒限制，有时会超时。在点击提交以创建客户之前，我切换到 jQuery 上传和 S3 上传图像，事后使用 Paperclip 作为延迟工作。这工作得很好——除了它在 #create 时继续超时，当我查看浏览器的左下角时，它显示 "Uploading (XX%)"，就好像它在 #create 时上传已经上传的文件一样。我拔头发了。
同样，照片可以很好地加载到 S3。在快速连接上，这不会超时，一切正常。在较慢的连接上，点击表单上的提交时超时（在成功上传图像后）。
代码如下。如果有人看到我遗漏的内容，我将不胜感激 - 为什么此表单会再次尝试提交照片？
#Controller

@s3_direct_post = S3_BUCKET.presigned_post(key: "photos/#{SecureRandom.uuid}/${filename}", success_action_status: 201, acl: :public_read)

params[:customer][:sms].gsub!(/[\s\-\(\)]+/, '')
end
@customer = current_salesperson.customers.build(customer_params)
if @customer.direct_upload_photo2_url?
@customer.turkee_status = "ready_to_send"
end
respond_to do |format|
if @customer.save
@customer.queue_processing
unless @customer.email.blank?
CustomerMailer.delay.welcome_email(@customer)
end
unless @customer.sms.blank?
send_sms
end
if params[:fbemail]
CustomerMailer.post_to_facebook(@customer).deliver
end
format.html { redirect_to @customer, notice: 'Customer was successfully created.' }
format.json { render action: 'show', status: :created, location: @customer }
else
format.html { render action: 'new' }
format.json { render json: @customer.errors, status: :unprocessable_entity }
