Fixed bug where many-to-many relationship with uselist=False

2013-04-21T15:31:29+00:00

would fail to delete the association row and raise an error
if the scalar attribute were set to None.  Also in 0.7.11.

happy new year (see #2645)

- [feature] Adding/removing None from a mapped collection

2012-08-13T15:00:58+00:00

now generates attribute events.  Previously, a None
append would be ignored in some cases.  Related
to [ticket:2229].

- [feature] The presence of None in a mapped collection
now raises an error during flush.   Previously,
None values in collections would be silently ignored.
[ticket:2229]

move mapper-level UOW functionality straight into unitofwork also. there's

2012-07-14T16:52:21+00:00

no need for this to be per-mapper.   can't move dependency init
off of property though as this init needs to happen up front, added a test
to prove it.

- move all of orm to use absolute imports

2012-06-23T18:45:47+00:00

- break out key mechanics of loading objects
into new "orm.loading" module, removing implementation
details from both mapper.py and query.py. is analogous
to persistence.py
- some other cleanup and old cruft removal

happy new year

- "delete-orphan" cascade is now allowed on

2011-06-04T23:01:52+00:00

self-referential relationships - this since
SQLA 0.7 no longer enforces "parent with no
child" at the ORM level; this check is left
up to foreign key nullability.
Related to [ticket:1912]
- a lot of cleanup and refactoring on relationship()
init, clarification

- and fix the message that was the actual subject of [ticket:2063]
