Default to using current mapped class as owner if none found

2018-02-20T21:42:24+00:00

Repaired regression caused in 1.2.3 and 1.1.16 regarding association proxy
objects, revising the approach to :ticket:`4185` when calculating the
"owning class" of an association proxy to default to choosing the current
class if the proxy object is not directly associated with a mapped class,
such as a mixin.

Search through mapper superclass hierarchy for owner

2018-02-09T21:31:24+00:00

Fixed regression caused by fix for issue :ticket:`4116` affecting versions
1.2.2 as well as 1.1.15, which had the effect of mis-calculation of the
"owning class" of an :class:`.AssociationProxy` as the ``NoneType`` class
in some declarative mixin/inheritance situations as well as if the
association proxy were accessed off of an un-mapped class.  The "figure out
the owner" logic has been replaced by an in-depth routine that searches
through the complete mapper hierarchy assigned to the class or subclass to
determine the correct (we hope) match; will not assign the owner if no
match is found.  An exception is now raised if the proxy is used
against an un-mapped instance.

Rework synonym, synonym_for documentation

2018-01-24T23:03:58+00:00

The map_column example was incorrect, and overall the purpose
of this parameter as well as that of synonym_for was not explained;
examples added along with more encouragement to use hybrids.

Resolve AliasedClass when determining owning class of association proxy

2017-10-24T00:36:18+00:00

Fixed bug where the association proxy would inadvertently link itself
to an :class:`.AliasedClass` object if it were called first with
the :class:`.AliasedClass` as a parent, causing errors upon subsequent
usage.

Protect against cls weakref becoming None

2017-05-08T22:37:40+00:00

Protected against testing "None" as a class in the case where
declarative classes are being garbage collected and new
automap prepare() operations are taking place concurrently, very
infrequently hitting a weakref that has not been fully acted upon
after gc.
