* partial cherry-pick of master flake8. clean cherrypick for lib and test,Mike Bayer2019-01-051-1/+1
| | | | | | | manually merged exaples. Change-Id: I9532d3b13d13f2769e6ca48eea23dd7d4041f68f (cherry picked from commit e3bdd80c6661c0e95fb67998c57540be667ce761)

| | | | includes adjustment to setup.py to recognize __version__ correctly
* Add Query.lazy_load_from attribute for shardingMike Bayer2018-06-041-1/+7
| | | | | | | | | | | | | | | | | | | Added new attribute :attr:`.Query.lazy_loaded_from` which is populated with an :class:`.InstanceState` that is using this :class:`.Query` in order to lazy load a relationship. The rationale for this is that it serves as a hint for the horizontal sharding feature to use, such that the identity token of the state can be used as the default identity token to use for the query within id_chooser(). Also repaired an issue in the :meth:`.Result.with_post_criteria` method added in I899808734458e25a023142c2c5bb37cbed869479 for :ticket:`4128` where the "unbake subquery loaders" version was calling the post crtieria functions given the :class:`.Result` as the argument rather than applying them to the :class:`.Query`. Change-Id: I3c0919ce7fd151b80fe2f9b5f99f60df31c2d73d Fixes: #4243 (cherry picked from commit a574b409296ef793cec8e1d00f1f7be48f15325e)
* Add an identity_token to the identity keyMike Bayer2017-12-221-99/+106
| | | | | | | | | For the purposes of assisting with sharded setups, add a new member to the identity key that can be customized. this allows sharding across databases where the primary key space is shared. Change-Id: Iae3909f5d4c501b62c10d0371fbceb01abda51db Fixes: #4137

* Lots of fixes to the code examples to specify imports explicitly.Michael Trier2009-03-311-7/+8
| | | | | | | Explicit imports make it easier for users to understand the examples. Additionally a lot of the examples were fixed to work with the changes in the 0.5.x code base. One small correction to the Case expression. Thanks a bunch to Adam Lowry! Fixes #717.
