Show me the content_tag_for code you are using in your view. Copy and paste.
The id that will be rendered depends on the instance variable that you send
into the helper. It doesn't care about the surrounding page or the route that
it took to render it.
If you pass in <%= content_tag_for :li, @foo do %> then you will get <li
id="foo_124">, no matter on which page you put this. (The controller for that
page must set @foo to be an ActiveRecord object, but that's the only
expectation.)
