Yes I was in a rush to get to a Halloween party, ok here is sample code.
db.define_table('person', Field('name'), Field('address'),
Field('referred_by', 'reference person'))
So when a person fills out a form, they enter the name of the person that
referred them, I do a query, and insert that record in the field
.....
SQLFORM.factory(db.person.fields....)
if form.accepts(....):
referrer = db(db.person.name ==
request.vars.referred_by.capitalize()).select().first()
db.person.insert(name=request.vars.name, address=request.vars.address,
referred_by=referrer)
WIth this code, that exception is thrown, every single time.
However if i did
if referrer:
referrer = referrer.id
else: referrer = None
It works correctly.
I was under the assumption that with the new DAL features in 1.70.1 that the
former code would have worked? Am I mistaken and still have to reference it
by id when inserting new records?
