In most cases you need one try/except at the place where you
application starts processing the request. Something like:
def receive_request_from_web_server(request, retries=3):
try:
handle_request(request)
except DisconnectionError:
if retries:
# Probably want to sleep for a few seconds here, to give
# the database a chance to recover
receive_request_from_web_server(request, retries - 1)
else:
raise
def handle_request(request):
# Application logic for the request

That's not really possible with transactions. You need to start a new
transaction and perform your operation from scratch.
Thanks,
