I moved `db.session.commit()` outside the loop. That seemed to fix the

I want to query rows and copy them while changing an attribute of each.
Here's my code.
colObjs= db.session.query(Column).filter_by(chart_id=oldChartID).all()
for colObj in colObjs:
make_transient(colObj)
print colObj.id
del colObj.id
colObj.chart_id= newChartID
Thank you

Thanks, I used the first method. Follow up question: How do I get the new
primary key after running `session.commit()`?
