I'm try to use a lambda to set a default value based on a value in
another table. Here is my model:
db.define_table('trip_instance', timestamp, sos_table,
Field('trip_type_id', db.trip_type, label='Trip Type',
widget=trip_select_widget, requires = IS_IN_DB(db, 'trip_type.id', '%
(name)s'), represent=lambda id:db.trip_type(id)['name']),
Field('total_slots', 'integer', default=lambda r:
db.trip_type(r.trip_type_id)['total_slots']),
Locally this causes an error that says:
TypeError: <lambda>() takes exactly 1 argument (0 given)
And on my server (Linode) there is no error but when I try and create
a new trip instance with sqlform the total slots field is pre-
populated with this:
<function <lambda> at 0x7f27684b7140>
My lambda looks almost identical to the one that works fine for
represent in the trip_type_id field except I'm using the table instead
of the field. Is that what I'm doing wrong?
