Loop action and view

Rails
1

I want to build a loop action, like:

def loop_action
@current_job = 0
100.each { |i| @current_job = i }
end

I want the view to display the @current_job information in realtime and
I’d like to have a stop button to stop the loop.

any idea to do this?

hi there,
you should look into the ajax/prototype helpers for this kind of
problem.
namely periodically_call_remote which lets your view call a remote
function that returns your @current_job
explained here:
http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M000528
and remote_function that would let you call a function that would stop
whatever it is that´s incrementing @current_job
explained here:
http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M000534

cheers

Thank you for replying.
Richard, it’s a nice plugin, maybe I’ll use it some day. But it seems
too funtionful for my current simple app, and by the way, it needs
flash.

both of these function will call an action, how can I request an action
to act on another action?

How about take the action directly into the view?
like
<%

for job in @jobs%
#codes to display job and do other things…

end
%>

if this works, a looooong page will be rendered, (Will it be rendered
when the loop ends or whenever a loop render a display content?)

and still, I have no idea how to stop the loops with a button.
