Oops.
db(db.table.refrence == db.refrencedtable.id).select(db.table.ALL, orderby=
db.refrencedtable.Field)
mind that there have to be records referencing each other, i.e.
db.refrencedtable
*1*, aaa
*2*, bbb
*3*, ccc
db.table
1, 'title1', *1*, ...
2, 'title 2', *1*, ...
3, 'title 3', *1*, ....
4, 'title 4', *2*, ....
i.e. bold numbers in table needs to be the same of ids used in
refrencedtable
