I finally find how to do :
In the controler I create a method :
def update_nbpiece
@production = Production.find(params[:id])
render :text=>@production.numbers
end
Then in the index.html.erb, inside the for loop :
<%= periodically_call_remote(:update => "nbpiece_id_" + production.id.to_s,
:url => {:action => "update_nbpiece", :id=>production.id}, :frequency => 1
)%>
...
<td id="nbpiece_id_<%=production.id%>"><%=h production.numbers%></td>
...
Now the strange thinks, is that when use the Aptana's internal browser, it
works, but when I run another web browser, like IE or Firefox, I got the
following error :
*PeriodicalExecuter is not
