delta/python-packages/sqlalchemy.git/lib/sqlalchemy/orm/query.py, branch pr/317 github.com: zzzeek/sqlalchemy.git Ensure .mapper is set on _ColumnEntity 2016-10-21T14:42:14+00:00 Mike Bayer mike_mp@zzzcomputing.com 2016-10-21T13:34:32+00:00 1f32d014da5d40406cd5d3996be5283c2fc57b26 _ColumnEntity didn't seem to have .mapper present, which due to the way _mapper_zero() worked didn't tend to come across it. With :ticket:`3608` _mapper_zero() has been simplified so make sure this is now present. Also ensure that _select_from_entity is an entity and not a mapped class, though this does not seem to matter at the moment. Fixes: #3836 Change-Id: Id6dae8e700269b97de3b01562edee95ac1e01f80

It wasn't clear how this differs from order_by(None);
add more tests and document that this has to do with whether or
not mapper.order_by will be re-enabled as well.

This replicates the same behavior as order_by().

order_by() will also be updated to deprecate passing
of False as this is no longer functionally different
than passing None.
