pls try :
db.define_table('b_tbl', Field('a_tbl_id', 'reference a_tbl')
,Field('name') )
db.define_table('c_tbl', Field('b_tbl_id', 'reference b_tbl')
,Field('name') )
i think in b_tbl, field id is already there as the integer auto increment
primary key, so when you redefine another field with the same name, it can
cause an error.
best regards,
stifan
