More specifically, when you provide the "next" argument to
SQLFORM.process(), it ultimately calls redirect(), which raises an HTTP
exception. If you put the .process() call inside a try/except, that HTTP
exception will get caught, and in your case, you are then ignoring it. We
should probably spell this out more clearly in the book.
You could instead do something like:
except Exception as e:
if isinstance(e, HTTP):
raise e # re-raise the exception in case of a redirect
redirect(URL('index'))
But generally it is much better to catch specific exceptions.
