Let me give more details..
I am trying to write a web-based multi-protocol client. There is an
opensource messenger Pidgin. Pidgin also comes with a dbus interface
with which, you can talk to pidgin, and do all the stuff provided by
pidin through scripts. Pidgin has signal handling system. For certain
events, corresponding signals will be raised. Through dbus, I am
registering a python function (message_received) as a callback
function which listens to "message received" signal. This function
will be called when ever a new message is received on Pidgin. Now I
have to do **something** inside the message_received function which
will render the the received message on my Template.
Is there an automatic way of updating my template from this view?
Right now, the way I am doing is, I am using Ajax.PeriodicalUpdater,
and polling every second for new messages. This is very inefficient
and I think this is not a scalable solution. With out continuous
updating, if I can update the template from message_received callback
function, only when message is received, that will be great.
Could someone throw some light in this? Even some hints will be
great.
-------------------- Signal Handling inside a Django View ------------
def message_received(account, sender, message, conversation, flags):
# here I should do something to make this message popup in my
# template. I think I cannot use the render_to_response directly
here
# this function is not called by a Httprequest
class SignalListner(threading.Thread):
run(self):
import dbus, gobject
from dbus.mainloop.glib import DBusGMainLoop
dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
bus = dbus.SessionBus()
bus.add_signal_receiver(my_func,
dbus_interface="im.pidgin.purple.PurpleInterface",
signal_name="ReceivedImMsg")
loop = gobject.MainLoop()
loop.run()
SignalListner().run()
----------------- end of view -------------------
Thanks a lot
