thank you so much for detail explanation, Anthony.
what i want to achieve is maximum number of allowed values same like total
counted record that store in reference table
e.g.
count_test1 = db(db.test1.id > 0).count()
db.define_table('test0',
Field('test1', 'list:reference test1'),
format = '%(test1)s')
db.test0.test1.requires = IS_IN_DB(db(), db.test1.id, db.test1._format,
multiple = (1, count_test1) )
thanks and best regards,
stifan
