Rails - Jul 2006 - trouble with render :partial from controller

Hi,
I''m definitely a newbie on rails here.  My very first attempt has gone 
well up until this point, but for some reason, when I try to do a render 
partial, I''m getting a full screen refresh.

I did a render partial just fine from an rhtml file.  This problem is 
specifically when calling render :partial => "my_partial" from the 
controller''s .rb code.  It''s just really one line that is not
doing what
it''s supposed to...

    render :partial => "my_partial_file"

It is indeed finding the file (_my_partial_file.rhtml) and rendering it, 
but it is not doing it as a partial.  It is refreshing the screen and 
rendering this partial file without any of the original page goodies.


thanks,
jp

P.S.
A friend of mine is trying to get me to use the scriptaculous 
visual_effect stuff to do this, and I probably will, but first I would 
like to understand what''s going on with a simple render :partial.

If you render a partial directly from an action, and that action has 
*not* been called via Ajax, the partial is all you''ll get.

If you''re trying to update just a portion of the screen, that action 
would need  to be called via ajax, and told which div to replace/update 
etc.

Are you invoking the action via Ajax (link_to_remote, etc)
