I'm tryng this:
db.define_table('ni',
SQLField('cliente',db.clientes),
SQLField('desenho',db.desenhos),
SQLField('descricao','text'),
SQLField('componente','string', length=03, default='Não'),
SQLField('origem_materia_prima','string', length=10,
default='Cliente'),
SQLField('ni_componente_01','references ni'),
SQLField('ni_componente_02','references ni'),
SQLField('ni_componente_03','references ni'),
SQLField('ni_componente_04','references ni'),
SQLField('ni_componente_05','references ni'),
SQLField('ni_componente_06','references ni'))
db.ni.cliente.requires=IS_IN_DB(db, 'clientes.id',
'clientes.razao_social')
db.ni.desenho.requires=IS_IN_DB(db, 'desenhos.id', 'desenhos.codigo')
db.ni.descricao.requires=IS_NOT_EMPTY()
db.ni.componente.requires=IS_IN_SET(['Sim', 'Não'])
db.ni.origem_materia_prima.requires=IS_IN_SET(['Cliente', 'Comprada'])
db.ni.ni_componente_01.requires=IS_NULL_OR(IS_IN_DB(db, 'ni.id',
'ni.id'))
db.ni.ni_componente_02.requires=IS_NULL_OR(IS_IN_DB(db, 'ni.id',
'ni.id'))
db.ni.ni_componente_03.requires=IS_NULL_OR(IS_IN_DB(db, 'ni.id',
'ni.id'))
db.ni.ni_componente_04.requires=IS_NULL_OR(IS_IN_DB(db, 'ni.id',
'ni.id'))
db.ni.ni_componente_05.requires=IS_NULL_OR(IS_IN_DB(db, 'ni.id',
'ni.id'))
db.ni.ni_componente_06.requires=IS_NULL_OR(IS_IN_DB(db, 'ni.id',
'ni.id'))
And I receive this error message:
SyntaxError: Field: unknown field type: references ni for
