Which is where I'm at now and yes very ew

I guess its conditionally included partials that are giving me grief.

There appears to be no clean mechanism for dealing with these. The best I
can come up with so for is to yield to a blocks within a shared partial that
sets up those other blocks of HTML code.

ie 

/views/layouts /application.rhtml
-----------------------------------
<HTML>
<BODY>

<%= yield :some_html_only_in_action_name_view %>

<h1>Some text in all views</h1>

<%= render :partial => 'some_partial' %>

<%= yield :layout -%>

<%= render :partial => 'some_other_partial' %>

</BODY>
</HTML>
-----------------------------------

/views/shared/action_name.rhtml
-----------------------------------
<% content_for :some_html_only_in_action_name_view do %>

  <b>Some text</b>
  <%= helper_method_or_other_bit_of_code_whatever -%>
  <em>some more text</b>

<% end %>

<h2>This is the action_)name page</h2>

<%= render :partial => 'shared_partial' %>

-----------------------------------

There's a nice article on drying up views here:
