滑軌+ SWFUpload的=

我的模型：（使用MySQL和我有字段：id, name, image, remote_image_url, created_at, updated_at）滑軌+ SWFUpload的=

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'%>

問題：爲什麼NoMethodError？爲什麼數據沒有嵌入數據庫？

UPD：

我刪除模型attached_file ...現在數據插入但..在這樣的觀點：

我看到'has_attached_file'，所以推測你使用的是Paperclip。您的'Gemfile'中是否有Paperclip，並且您是否使用'bundle install'安裝了捆綁包？ –

SWF_uploader_fu僅適用於回形針？如果我刪除has_attacged_file？請在帖子中查看我的更新！ –

我不明白你的問題。我不知道「SWF_uploader_fu」是什麼，Google的搜索結果爲零。如果您使用的是特定的寶石或教程，應該鏈接到它。 –
