載波文件未上傳Rails4

Question

一切正常，除了存儲的image1字符串為nil。 有沒有辦法找到載波產生的誤差。

這是控制器

def create_post

@post = Post.new(:club => params[:club],:venue => params[:Venue], :title => params[:title] , :shortdesc => params[:shortdesc],:longdesc => params[:longdesc] ,:category => params[:category],:eventdatetime => params[:eventdatetime],:video1 => params[:video1],:file1 => params[:file1],:file2 => params[:file2],:file3 => params[:file3])
    @post.image1 = params[:image1]
    if @post.save
        redirect_to '/'+params[:club]
    else
        redirect_to '/admin'
        flash[:notice] = "Post could not be saved at the moment, try later"
    end

end

上載者：

class Image1Uploader < CarrierWave::Uploader::Base
storage :file
def store_dir
 "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end

模型：類Post <ActiveRecord :: Base

mount_uploader :image1, Image1Uploader
validates_integrity_of :image1
validates_processing_of :image1
validates_download_of :image1
end

記錄已插入：

 Post Load (0.3ms)  SELECT  `posts`.* FROM `posts` WHERE `posts`.`id` = ? LIMIT 1  [["id", 49]] => #<Post id: 49, club: "Joy", title: "", date: nil, timr: nil, image2: nil, image3: nil, video1: "", video2: nil, file1: "", file2: "", file3: "", shortdesc: "", longdesc: "", category: nil, created_at: "2016-01-10 17:35:54", updated_at: "2016-01-10 17:35:54", eventdatetime: "2016-01-15 23:00:00", venue: "", image1: nil>

文件似乎沒有上傳，因為在幾秒鍾內加載了下一頁，並且文件大小足夠大，至少需要30秒才能上傳。

Answer 1

也許存在與遠程提交多部分表單有關的問題，您可以嘗試使用此gem，在這種情況下它對我有幫助： https : //github.com/JangoSteve/remotipart

更新：

在遠程提交表單時，應在操作中呈現json而不是默認行為：

def create_post
  @post = Post.new(:club => params[:club],:venue => params[:Venue], :title => params[:title] , :shortdesc => params[:shortdesc],:longdesc => params[:longdesc] ,:category => params[:category],:eventdatetime => params[:eventdatetime],:video1 => params[:video1],:file1 => params[:file1],:file2 => params[:file2],:file3 => params[:file3])
  @post.image1 = params[:image1]
  if @post.save
    render json: {post: @post, error: false}
  else
    render json: {error: true}
  end
end

Answer 2

我切換到from_for及其工作，也許我使用的form_tag語法存在一些問題。 感謝@hedgesky嘗試幫助我。
