为什么我从show.js.erb文件中得到这个错误？

我有这样的代码在我的个人资料显示的看法：为什么我从show.js.erb文件中得到这个错误？

<div id='main_profile_column'> 
    <div id="video_div"> 
    <% @videos.each do |video| %> 
     <%= render 'videos/video', :video => video %> 
    <% end %> 
    </div> 
     <%= paginate @videos %> 
</div>

和我使用的是show.js.erb文件来呈现视频，以实现AJAX分页部分。我有这个在我的show.js.erb文件：

$("#video_div").html("<%= escape_javascript(render("videos/video")) %>");

这个代码怎么给我这个错误：

GET http://localhost:3000/profiles/45?page=2&_=1302255080024 500 (Internal Server Error)

我应该是什么样的代码将在.js.erb文件？

下面是从日志中的错误：

这是你从development.log或在浏览器中得到了错误？ – 2011-04-08 06:43:21

from chrome debugger – 2011-04-08 06:47:06

在你的development.log中查看真实的错误 – 2011-04-08 06:47:56

是您@videos变量设置正确，在你的控制器/行动？

试试这个：

$("#video_div").html("<%= escape_javascript(render(:partial => "videos/video", :collection => @videos)) %>");
