abuse content_for

you should have a

<%= yield :head %>

line in your head tag so you can do

<% content_for :head do %>
  <%= javascript_include_tag 'foo', 'bar' %>
  <% javascript_tag do %>
    page specific javascript here
  <% end %>
<% end %>

in any page you like to include a javascript/css file. This way, all js and css files/code is found in the head tag of your page.

In the same way, you can have a partial that renders the sidebar of your application. In that partial, you can have

# Common sidebar items here
# Common sidebar items here

# Dynamic sidebar items here
<%= yield :sidebar %>

so you can have dynamic sidebar content by just adding

<% content_for :sidebar do %>
  page specific sidebar content
<% end %>
