Question

我正在更新使用ruby_filemagic上传图片的项目。在iFrame中有一个AJAX表单可以工作，但是当我将代码传输到另一个表单时，显然是相同的结构（例如也是multipart，指的是同一个对象，在这种情况下是@listing），它会抛出一个错误。

为什么会出现这种情况？

在AJAX环境中是否存在某些行为？

失败的表单标记如下所示：

<form action="/listings/add_description" class="edit_listing" enctype="multipart/form-data" id="edit_listing_26" method="post" onsubmit="return validateForm(this,'listing_description');">
<div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="2VyJP37Ff1ADOoB6ZDEtS4FrdxwGNgnqqstB+hoNWu0=" />

虽然有效的那个看起来像：

<form target="imageUpload" method="post" id="new_listing" enctype="multipart/form-data" class="new_listing" action="/listings">
<div style="margin: 0pt; padding: 0pt; display: inline;"><input type="hidden" value="2VyJP37Ff1ADOoB6ZDEtS4FrdxwGNgnqqstB+hoNWu0=" name="authenticity_token"></div>

成功上传（从第二张表格看起来像：

Processing ListingsController#create (for 12.13.14.15 at 2011-02-09 12:40:03) [POST]
  Parameters: {"commit"=>"Create", "action"=>"create", "authenticity_token"=>"2VyJP37Ff1ADOoB6ZDEtS4FrdxwGNgnqqstB+hoNWu0=", "listing"=>{"end_date(3i)"=>"9", "discount_percent"=>"", "name"=>"test", "thumbnail"=>#<File:/var/folders/Oo/Oooj578kHdy3igRanTaILU+++TM/-Tmp-/RackMultipart20110209-5842-ipfdzh-0>, "start_date_text"=>"now", "category_id"=>"22", "regular_price"=>"100", "description"=>"test", "end_date(1i)"=>"2011", "end_date(2i)"=>"2", "sale_price"=>"30"}, "controller"=>"listings"}

虽然失败的一个（来自非AJAX，第一个表单看起来如下。正在创建/ tmp中的文件，但/ var中的文件不是：

更新：根据要求，这是控制器操作：首先，操作一个，创建：

 def create
        @listing = Listing.new(params[:listing])
        @listing.merchant = Merchant.find(current_merchant)
        responds_to_parent do
            if @listing.save
                render :update do |page|
                    page.replace_html 'formView', :inline => "<div>Listing '#{@listing.name}' was successfully created.</div>"
                    page['formView'].setStyle('overflow' => 'auto')
                    page.delay(2) do
                        page.visual_effect(:toggle_appear, 'formView', :duration => 0.2)
                    end
                end
            else
                render :update do |page|
                    page.replace_html 'formView', :partial => 'new'
                end
            end
        end
    end

现在，失败的那个：

 def add_description 

      unless @listing.save || session["skip_validation"]
        session["skip_validation"] = true
        redirect_to :back
        return
      end

      @listing.current_step_index= session["current_step_index"] = 2
      @previous_stages = ["pre_listing","listing_comment"]
      @listing_partial = "complete_listing"
      render :partial => "listings", :layout => "application"
    end

我应该提一下，当表单中没有文件上传html时，行为“add_description”正在运行，但是没有对图像thumnail的验证，并且表单中的html直接从工作中复制形式...

ruby_filemagic以AJAX形式上传，不是其他
