Ok I just identified the issue. It seems that there is a conflict between 2
subqueries :
in my model.I have this :
statussen = relationship(
"PersoonStatus",
order_by="desc(PersoonStatus.status_datum)",
backref='persoon',
cascade='all, delete, delete-orphan',
lazy='subquery'
)
and if I do this query :
last_statuses = aliased(
statussen_table_name,
self.session.query(
getattr(statussen_table_name,
issue_id_field),
statussen_table_name.status_id)\
.join(Status).order_by(Status.datum.desc())\
.limit(1).subquery().lateral())
there is a conflict between this 2 subqueries who target the same table.
Is there a workaround to prevent this conflict?
any idea?
