Long Running task percentage indicator in rails

Rails
1

Hello friends,

I have to create a new project in rails which has a long running task,
so i need a way to indicate percentage of task completed.

updates like:

0% Task started
25% task completed
50% task completed
75% task completed
100% complete.
How can i send these task updates from controller action to view in
rails.

i find an example in asp.net here
http://encosia.com/2007/10/03/easy-incr … -requests/

how can i do the same thing in ruby on rails.

thanks
johnny

You can’t follow that approach directly as you can’t send back the
response bit by bit with rails (and it’s a bad idea to have such long
running actions because they will stop the mongrel accepting
connections). The usual approach is to offload the processing task to
something like backgroundrb.

can i use AJAX updating multiple times within the same controller
action?
which method should i use. for getting long running process with last
around 30 seconds.

in a nutshell no

which method should i use. for getting long running process with last

use backgroundrb, backgroundjob, with feedback via ajax.
