I would to know if it is possible to automaticly refresh some
particular field ?
Clearly, I have a model called "productions" with fileds "name" and
"numbers".
Another application update fields "numbers" of the mysql table.
On an "index.html.erb", I have the list of "production" and i would
like to view automaticly when value of "numbers" change.
First of all, is it possible ?
Because I may have many records, and in a close futur, more fields to
monitor, I would like to update just choosen filed and not the whole
page.
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 )%>
…
<%=h production.numbers%>
...
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 :
