That happens when the cast fails, so presumably either there is no URL arg (which results in a value of None) or the value of the first arg cannot be cast to an integer. Note, you can also specify an "otherwise" argument, which can either be a URL for redirect upon failure or a function that gets called upon failure (which itself may redirect or return an error).
Note, because of the "otherwise" argument, it is no longer necessary to use the "or redirect(...)" construction -- instead, just do: db.some_table(request.args(0, cast=int, otherwise=some_URL)) Anthony On Friday, January 16, 2015 at 2:58:29 PM UTC-5, Dmitry Ermolaev wrote: > > not worked...
