I have this field
db.define_table('B',
Field('my_table', db.A, notnull=False, ondelete="SET NULL"),
db.B.my_table.requires = IS_EMPTY_OR (
IS_IN_DB(db(db.A.author_id==auth.user_id),
db.A.id, '%(title)s'))
That means that my_table can have references from A but only the ones
that the same user has made OR is empty (None). And also when the
referenced object is deleted the value becomes None.
What i want to do is to remove a reference at some point. I have the
id of the entry i want to change and i do
db.B[id].my_table = None
but it doesn't work. Actually it doesn't allow me to change it from a
function. Do i do something wrong?
