I have in
<link href="/assets/application.css" media="screen" rel="stylesheet" type="text/css" />
<script src="/assets/application.js" type="text/javascript"></script>
but when I go to http://localhost:3000/assets/application.css
Routing Error
No route matches [GET] "/assets/application.css"
P.S. Rails 3.1.0.rc4, ruby 1.8.7
Seems Sprockets / Rails 3.1 were acting up for me w/ ruby 1.9.2-p180 … updating to Ruby-1.9.2-p290 seemed to stop the issue.
Maybe not related to your issue… but useful for anyone else having that issue using those versions of Rails & Ruby.
