Let's suppose that I want to disable my web app for a certain period of
time while I am updating the database and that I want to inform users that
maintenance is in progress?
1. In models I can create a global var MAINTENANCE_IN_PROGRESS = False
which I could thange to True when I want to do some maintenance tasks.
2. then in every function in every controller I could write something like:
def controller():
if MAINTENANCE_IN_PROGRESS:
Redirect_to_maintenance_message
else:
#do_controller_task
Is there some smarter way to do it without checking if maintenance is in
progress in every function?
