hi
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

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. regards, javier ramirez -- -------- Estamos de estreno... si necesitas llevar el control de tus gastos visita http://www.gastosgem.com !!Es gratis!! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
