internal_server_error

我做的depot例子，在多个视图中应用同一个布局时出现问题
在application.rb中，layout "store",在未使用同一布局时运行正常
log文件是：

ActionView::TemplateError (Missing template admin/_cart.html.erb in view path F:/work/depot/app/views) on line #18 of layouts/store.html.erb:
15: <div id="columns">
16: <div id="side">
17: <div id="cart">
18: <%= render(:partial => "cart", bject => @cart) %>
19: </div>
20: <a href="http://www....">Home</a><br />

不知道这是什么问题啊

admin/_cart.rhtml？
这个东西不应该是在store/_cart.rhtml么

对啊，是在store/_cart.rhtml中的

有人帮忙解答一下吗？
