I think this has been asked before but even though I searched Google I haven't come up with a solution.

So this is what I'm trying to do in Rails 2.3.5:

layouts/application.html.erb:
<html>
  <head>
    ... some other stuff
    <%= yield :head %>
  </head>
  <body>
    <% content_for :head, "something that belongs in the head" %>
  </body>
</html>

Notice the yield before the content_for.

I know that Rails - by default - doesn't allow the content of :head to be defined after yield has been used - makes sense.

I even tried hooking into the template render process but no success so far.

So my goal is to be able to define content_for inside partials/templates and have the "yield" somehow delayed and executed just before the response is send to the browser.

Has somebody come up with a solution?

Greetings and thanks, Frank

Update I'll go with weppos's idea and try myself on rack middleware. thanks
