Sorry, if you want to include a computed field in a SQLFORM, you must
explicitly pass in the "fields" argument listing all the fields you want to
include (if you want to include all fields in the table, including computed
fields, just do fields=legacy_db.ordinipo.fields).
Note, for create forms, there will be no value to display yet in the
"total" field, so to avoid having "None" displayed there, you might need to
specify a "represent" attribute to display an alternative value (such as an
empty string or "N/A"):
Field('total', compute=lambda r: float(r['preco'] * r['quantidade']),
represent=lambda v, r: '' if v is None else v)
