Rails - Apr 2006 - Initial load time when periodically_call_remote

When I do periodically_call_remote with e.g. :frequency => 30
after initial page load I have to wait 30 seconds until this partial 
renders first time. Does anybody know how to make ROR to render partial 
on web page load, and then start periodic calls every 30 seconds? I 
tried to put

<div id=''mydiv''><%= render(:partial,
:action=>''myaction'') %></div>
<% periodically_call_remote(:update=>''mydiv'', 
:url=>{:action=>''myaction''}, frequency=>30) %>

but it does not work somehow...

Please help!

:partial will be looking for a view/_partial, which isn''t wnat you
want,
as you''re trying to render an action.  Does render :action
=>''myaction''
work (without the partial)

Hi,

Yeah, your <%= render(:partial, :action=>''myaction'')
%> is broken.

If you want to render an entire action, you need to render as a component.

However, this is probably not what you should need to do. Look into
extracting partials, etc.

will try that.. I guess I tried before but it did not find template, 
while it finds template for periodic calls.

Do you have a views/mycontroller/myaction.rhtml file ?

Can you paste the source for ''myaction'' ?

Here it is:

<% @alarms.each do |a| %>
  <tr><td><%= a.start_time -%></td>
  <td><%= a.message -%></td></tr>
<% end %>

And here is how it works now, and takes 30 seconds before it appears on 
web page:

<div id=''mydiv''>&nbsp;</div>
<% periodically_call_remote(:update=>''mydiv'', 
:url=>{:action=>''update_alarms''}, frequency=>30)
%>

The way I do it is to call a separate function that does the same update 
call in the window.onload() handler, so there''s basically an extra AJAX
call immediately.  Not hugely efficient, but it works...
