我的模型：(使用mysql，我有字段：id, name, image, remote_image_url, created_at, updated_at)

require 'mime/types'
class Avatar < ActiveRecord::Base            

 has_attached_file :image, :styles => { :small => "150x150>", :large=> "320x240>" }

def swfupload_file=(data)
    data.content_type = MIME::Types.type_for(data.original_filename)
    self.image = data
  end

end

控制器

  def upload
    if params[:Filedata]
      @avatar = Avatar.new(:swf_uploaded_data => params[:Filedata])
      if @avatar.save
        render :partial => 'photo', :object => @avatar
      else
        render :text => "error"
      end
    else
      @avatar = Avatar.new params[:image]
      if @avatar.save
        flash[:notice] = 'Your photo has been uploaded!'
        redirect_to photos_path
      else
        render :action => :new
      end
    end
  end

Index.html.erb

<head>
  <title>.test.</title>
  <%=swfupload_head %>
</head>
<br/><br/>
<%=swfupload :controller=>'test',:action=>'upload'%>

===================================

而且我有

问:为什么是NoMethodError？为什么数据没有插入到数据库中？

更新：

我在模型attached_file中删除...现在插入了数据，但是..在此视图中：

下面是插件：https://github.com/jeroeningen/swfupload_45north

has_attached_file是给attachment_fu带来生机的方法。

gem假设您了解attachment_fu。它不是插件的一部分。这部分你得自己去做。
