Hi.
Imagine the following scenario:
session = DBSession()
readonly_model = session.query(ReadOnlyModel).get(id)
# Readonly means the model will NOT have its data changed in the life of
the transaction(s).
method_one(readonly_model.readonly_data, param_1, param_2, ...)

No that's not required at all. All the objects that are still referenced

That would indicate you add()-ed it during the transaction. Any data

Hello,
I'm trying to get the name of the columns of my tables, writing
columnDb = self.table.__table__.columns._all_cols
self.labels = [col.name for col in columnDb]
