I get NONE. I have these:
db.define_table('supplier',
Field('suppliercode'),
Field('suppliername'),
Field('pricecoeficient'),
format='%(suppliercode)s')
db.define_table('product',
Field('series', 'reference series'),
Field('suppliercode','reference supplier'),
Field('price'),
Field('cost'),
Field('cost',compute=lambda r: r['price']*db.supplier[r.supplier_id].
pricecoefficient))
and I am using SQLFORM.grid which automatically assigns a supplier to the
record. I assumed it would pick up the pricecoefficient and do the
calculation but I think I am missing something.
