SQLAlchemy BESTELLEN DOOR AFDALEN?

| | |

Hoe kan ik ORDER BY descending gebruiken in een SQLAlchemy-query zoals de volgende?

Deze query werkt, maar retourneert ze in oplopende volgorde:

query = (model.Session.query(model.Entry) .join(model.ClassificationItem) .join(model.EnumerationValue) .filter_by(id=c.row.id ) .order_by(model.Entry.amount) # Deze rij :) ) 

Als ik het probeer:

.order_by(desc(model. Entry.amount)) 

dan krijg ik: NameError: globale naam "desc" is niet gedefinieerd.
