Rails - override page element when using a partial or a specific controller view

Question

Is there a way to append or override the <head> page element inside a rails view?

Suppose I have something I only want to include in a particular view's <head>, and I am using the application.html.erb in order to render the rest of my views. In this case I do not want to discard application.html.erb but instead just append to it's head element for one particular page and nothing else.

In your application.html.erb:

<head>
  <% if content_for? :for_head %>
    <%= yield :for_head %>
  <% end %>
</head>

In your "specific" view:

<% content_for :for_head do %>
  Something-to-put-in-head
<% end %>

:for_head isn't predefined: naming it is up to you. It could be anything.
