As noted in the documentation
<http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#Legacy-databases-and-keyed-tables>,
the .update_record method is not available on rows of keyed tables, so you
will therefore also not be able to use the built-in .update_or_insert
method (which uses .update_record internally). Instead, you can write your
own function -- as you can see here
<https://github.com/web2py/pydal/blob/v16.06.28/pydal/objects.py#L792>,
it's a fairly simple function. Also, feel free to submit a Github issue
about this (link back to this discussion), as I don't think it would be
difficult to refactor .update_or_insert to accommodate keyed tables.
