assuming certain column names...

INSERT one

newToner = Toner(toner_id = 1,

toner_color = 'blue',

toner_hex = '#0F85FF')

dbsession.add(newToner)

dbsession.flush()

INSERT multiple

newToner1 = Toner(toner_id = 1,

toner_color = 'blue',

toner_hex = '#0F85FF')

newToner2 = Toner(toner_id = 2,

toner_color = 'red',

toner_hex = '#F01731')

dbsession.add_all([newToner1, newToner2])

dbsession.flush()

UPDATE

q = dbsession.query(Toner)

q = q.filter(Toner.toner_id==1)

record = q.one()

record.toner_color = 'Azure Radiance'

dbsession.flush()

or using a fancy one-liner using MERGE

record = dbsession.merge(Toner( **kwargs))
