python - Multiple Table Transactions SQLAlchemy -


i'm trying save 2 tables. let need insert tbl_1 first , use generated id inserted tbl_2 after insert call commit command. on current approved 

tbl_1.add(data1) tbl_1.commit()  -- retrieve id tbl_1 tbl2.add(tbl_1.id, data2) tbl2.commit()

the problem approach if tbl2.add fails need delete added tbl_1. , don't having delete action since table id incrementation messy. i'm thinking this

tbl_1.add(data1) tbl2.add(tbl_1.id, data2) tbl2.commit()

any idea on how achieve using sqlalchemy?

***** edit ****** tbl_1 , tbl2 same session object of sqlalchemy. tried setting autocommit true , works did was

tbl_1.add(data1) tbl_1.flush() tbl2.add(tbl_1.id, data2) tbl2.commit()

are there problems setting autocommit true or false?
