After:
db.define_table('test',
Field('name', writable=False),
Field('refers_to', 'reference test'))
add
db.test.referes_to.requires=IS_EMPTY_OR(IS_IN_DB(db,'test.refers_to'))
or it will not take a empty reference.
On a second thought... this should probably be the default behavior
for self-references.
