【问题描述】:
我的个人资料显示视图中有此代码:
<div id='main_profile_column'>
<div id="video_div">
<% @videos.each do |video| %>
<%= render 'videos/video', :video => video %>
<% end %>
</div>
<%= paginate @videos %>
</div>
我正在使用 show.js.erb 文件来渲染视频部分以实现 AJAX 分页。我的 show.js.erb 文件中有这个:
$("#video_div").html("<%= escape_javascript(render("videos/video")) %>");
这段代码如何给我这个错误:
GET http://localhost:3000/profiles/45?page=2&_=1302255080024 500 (Internal Server Error)
我应该在 .js.erb 文件中添加什么代码?
这是日志中的错误:

【问题讨论】:
-
这是您从 development.log 或浏览器中得到的错误?
-
在你的 development.log 中查看真正的错误
-
如果我不得不猜测,我会说
video为空,而div_for中的代码正在尝试调用model_name的方法。
