With this relationship
Record.mapper = sa.mapper(Record, records,
properties={
'tinwsys' : sa.relation(Tinwsys, secondary=records_tinwsys,
backref=sa.backref('efile_records')
}
)
SA is deleting associated records in records_tinwsys when a Tinwsys
record is deleted. This only occurs when backref is defined. The
intended behavior is for nothing to happen to records_tinwsys when a
Tinwsys record is deleted. How do I accomplish this?
