Rails - Feb 2005 - render_collection_of_partials vs. loop whats the difference ?

This is likely a problem with my interpretation of the documentation.

I have two classes joined by a table with appropriate relationships between 
both. I currently have a single record in the join table to test things.

If I use the following in the view (HTML excluded), I get one item returned 
and rendered:

<% @foo.bars.each do |@bar| %>
 <%= @bar.data %>
<% end %>

I thought from the docs that this could be rewritten as

<%= render_collection_of_partials "bar", @foo.bars %>

With, <%= @bar.data %> in _bar.rhtml.

With the former, I get the expect single record result. With the latter, I get 
a single iteration, but my @bar doesn''t have any data.

Have I misunderstood the function of r_c_o_p ?

Thanks,

Have you tried dropping the @ from <%= @bar.data %> in _bar.rhtml so
it is just <%= bar.data %> ?

I belive that the object passed into a partial is accessable by a
variable equal to the file name minus the prefixed underscore.  At
least, thats what''s working for me.

No prob.  Easy questions are my specialty.  :)
