You can explicitly specify the id field of a table:
Field('id', type='id', ...)
And you can even give it a different name:
Field('myid', type='id', ...)
See http://web2py.com/books/default/chapter/29/6?search=named+id+field.
But why do you want to set ondelete for an id field -- it's supposed to be
used for reference fields?
