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 "removed\_email\_address@domain.invalid\_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

Your div ids need to be unique.

just generate a unique string “log\_entry\_#{c.id}”

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 %\>
