Model:
---------
db.define_table('tbls',
SQLField('name'))
db.define_table('xref',
SQLField('table_id','reference tbls'),
SQLField('entry_id','integer'))
db.define_table('tbl1',
SQLField('info1'))
db.define_table('tbl2',
SQLField('info1'),
SQLField('info2'))
db.define_table('tbl3',
SQLField('info1'),
SQLField('info2'),
SQLField('info3'))
dt=[t for t in db.tables if t not in ['tbls','xref']]
db.tbls.name.requires=IS_IN_SET(dt)
db.xref.table_id.requires=IS_IN_DB(db,db.tbls.id,'%(name)s')
Controller:
-------------
def insert_entry():
# some form/forms here that select which table to make an entry in
and display a create form for it, updating entry_id afterwards.
I hope this makes it more understandable.
