IntegrityError is defined by the database driver, so needs to be imported.
Actually, I forgot, we made this easier, so it is not adapter-dependent --
you can do:
try:
...
except db._adapter.driver.IntegrityError:
...
Another option is:
def insert_error_handler(table, fields, error):
[handle the error]
db.mytable._on_insert_error = insert_error_handler
There is also an _on_update_error callback.
