Rails - Mar 2006 - Passing values to a Partial

Hi,

I cannot seem to find out how to pass in a value to a partial. Can 
anyone help me?

What I am doing(in the code below) is calling a function in my 
controller called setobject. This function just redraws the partial. I 
want to be able to change the value @objectname, redraw my partial and 
have it be able to use that value. The first the page is drawn it works, 
but when i call setobject it says that @objectname is null in my partial 
and it throws an error.


Code follows.

In my index.rhtml I have the following:
  <%= render :partial => "properties" %>

with some other code later on in the file
<%= drop_receiving_element "dcwindow",
		      :update => "items", :url => { :action =>
"setobject" },
		      :accept => "products", :hoverclass =>
"cart-active",
		      :loading => "Element.show(''indicator'')",
		      :complete => 
"Element.hide(''indicator'');additem(element.alt,element.id);"
		      %>

In _properties.rhtml I have:
<%
    command = @objectname
%>
Which I then use later on.

In my controller file I have:
  def index
    @objectname = "Plane"
  end
  def setobject
    render :partial => "properties"
  end


Thank in advance!
Kent

Here are some details about render():
http://api.rubyonrails.org/classes/ActionController/Base.html#M000205
Specifically, the Rendering Partials section.
# Renders the same partial but also makes a local variable available  
to it
   render :partial => "win", :locals => { :name =>
"david" }

if the following change in the controller doesn''t
work
> render :partial => "properties", :locals => {:@objectname
=>
> @objectname}
you might have to do
> render :partial => "properties", :locals => {:objectname
=>
> @objectname}
and in _properties.rhtml change
> <%
>     command = @objectname
> %>
to
> <%
>     command = @objectname || objectname
> %>
