Can any one tell me why i get such large number of POST messages to
the WEBBRICK...
It is crashing my WINDOWS within 5 minutes.
I am trying to make a portlet that will periodically refresh the stock
quotes. The quotes are arranged in atable and pulled from mysql
database .
I have a controller(mainpage_controller.rb)
======def index
@ticker_pages, @tickers = paginate :nsecurrent, :per_page => 20
end
============my view layout(mainpage.rhtml)
<html>
<head>
<title >TEST APPLICATION</title>
<%= stylesheet_link_tag "list", :media => "all"
%>
<%= javascript_include_tag :defaults %>
<body>
<%= @content_for_layout %>
</body>
</html>
================my view ( index.rhtml)
<%= render :partial => "ticker_box",:layout => false %>
===================my partial (_ticker_box.rhtml)
<%= periodically_call_remote( :update => "myinfobox",:frequency
=>
60,:url => { :action => "index" } ) %>
<div id="myinfobox" class="update">
<h1 align="right" class="ListTitle2">Ticker Listing at
<%= Time.now
%></h1>
<table align="right" cellpadding="3"
cellspacing="2">
<tr valign="top" class="ListTitle0">
<td align="right"class="ListTitle2">TICKER</td>
<td align="right"class="ListTitle2">OPEN</td>
<td align="right"class="ListTitle2">HIGH</td>
<td align="right"class="ListTitle2">LOW</td>
<td align="right"class="ListTitle2">CURRENT</td>
</tr>
<%
odd_or_even = 0
for product in @tickers
odd_or_even = 1 - odd_or_even
%>
<tr valign="top" class="ListLine<%= odd_or_even
%>">
<td
align="right"class="ListTitle0"><%h(product.symbol.slice(0,product.symbol.length-3))
%>
</td>
<td align="right"class="ListTitle0">
<%= product.open %>
</td>
<td align="right"class="ListTitle0">
<%= product.high %>
</td>
<td align="right"class="ListTitle0">
<%= product.low %>
</td>
<td align="right"class="ListTitle0">
<%= product.current_val %>
</td>
</tr>
<% end %>
</table>
</div>

Before even looking at your code, you should be able to tell what the problem is based on the behaviour, but let''s take a look at the code anyway (snipped to show the relevant lines):> my view ( index.rhtml) > <%= render :partial => "ticker_box",:layout => false %>> my partial (_ticker_box.rhtml) > <%= periodically_call_remote( :update => "myinfobox",:frequency => > 60,:url => { :action => "index" } ) %>index.rhtml is including a partial which updates part of the page with index, which includes a partial, which updates part of its page with index... Can you see where this is going? :) This is known as mutual recursion.> It is crashing my WINDOWS within 5 minutes.Do you mean your browser windows? After 5 minutes, it should still only be around 2^4 requests -- if this is crashing Windows, you probably have other issues with your OS.

Thanks I could get rid of the issue by putting the periodically_call_remote in the index.rhtml .
