I realized at the grocery store last night that entering 0 (which I
assume is an invalid ID) instead of nothing (equal to '') would
resolve the problem because:
>>> x = int('')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: ''
But what I don't understand is why the examples in the book don't have
that problem:
http://www.web2py.com/book/default/chapter/06#Self-Reference-and-Aliases
And, of course, I'm too noob to know what the code web2py code should
actually do.

I still get pretty much the same exception:
