Issues with update div using ajax

Hi!
I have been trying to use periodically_Call_remote in a table showing
various devices , to update a row specific to a device.

my view looks like:

All Devices


</tr>

<% @devices.each do |c|%>

<%= javascript_include_tag :defaults %> <%= periodically_call_remote(:update => "log_entry", :url => {:action => 'get_ping_entry', :id => c.id}, :frequency =>3) %> <% end %>
Device Name Ping Result
<%=h c.name%>
<%= will_paginate @devices %>

and my controller action is :

def get_ping_entry
@dev=Dev.find(params[:id])
@status= Ipaddr.find(:first,:conditions=>[“dev_id
=?”,@dev.id]).status
render_text "status "[email protected]_s
end

its working fine but its updating only the first row i.e. its showing
result of periodically call remote for every device in the first row
only…not in the corresponding row for each device…

can you please help me with this??
thanking in advance

just generate a unique string “log_entry_#{c.id}”

Get your erb right: <%= c.id%> (you could tell this was the problem by
looking at the html output)

If you’re in Rails 2.x, use the dom_id method to create the id

~

Or, since you specifically want a div:

<% div_for device do %>

<% end %>
