I do a lot of inserts (duration about 3 min) and would like to show a
progressbar for the user during this inserts. I tried out to do it with
threads, but without a success. Also forking a process doesn’t work
(Windows XP). Somebody has an idea?
thanks in advance
masu
example:
this is my loading function
def load_data
Thread.new do
load_data_into_another_db …
end
end
this is a ajax function, which is called periodically
def ajax_update_progress_bar
Thread.new do
render :text => Time.now.to_s
end
end
I do a lot of inserts (duration about 3 min) and would like to show a
progressbar for the user during this inserts. I tried out to do it with
threads, but without a success. Also forking a process doesn’t work
(Windows XP). Somebody has an idea?

I had to do something similar recently. You can exec “start whatever” in
windows and it will start a new process with the command line you
provide (rake or ruby script/runner for example). The option /B will
even hide the window for the new process.
Regarding to the communication back to the user, I did it by creating a
“semaphore” file at launching time and deleting it at completion.
Meanwhile I had a small ajax magic querying every n seconds back to the
server and just checking if the semaphore was still alive. I was also
showing a timestamp back to the users so they could know everything was
peachy on the server side.
I know more solid solutions like Drb are available and recommended, but
this one doesn’t need any installation/monitoring and it works fine for
simple tasks.
