Book states:
Code in models, views and controllers is enclosed in web2py code that
looks like this:
try:
execute models, controller function and view
except:
rollback all connections
log the traceback
send a ticket to the visitor
else:
commit all connections
save cookies, sessions and return the page
If the db update failed in the regular controller I would assume that
a ticket page would appear. But what if the db update is in a callback
function?
@Anthony, it seems that a db update failure would cause the rest of
the callback code to be not executed and so the flash='failure'
message won't appear at all.
