Use a Progess bar, but not for upload?

Hi,

It is possible to use a progess bar, but not only for uploading file???
like long calculation time or database access???

Thanks you very much!!!

If you use Ajax calls, you can specify the :before and :after
parameters to show and hide a spinner/timer graphic.

If you need to actually show the % of work/file completed, you’ll need
to setup a process which has the status available, and call
perdiocally_call_remote to check with the server what the status is
(assuming its taking longer then regular client/server communication).
The returning value would be a percentage/fraction, and you display a
graphic associated with that percentage. If you want to get
sophisticated, you may be able to run threads to split the progress

Hope this helps.

If you want to execute a long-running process and not have it block
the application, you’ll need to use something like backgroundrb
(http://backgroundrb.rubyforge.org/). Then you can use a
periodically_call_remote ajax callback to grab the status and update
the progress bar.
