Move pk on single-inh subclass check below conflict resolution check

2018-10-30T17:31:53+00:00

The column conflict resolution technique discussed at
:ref:`declarative_column_conflicts` is now functional for a :class:`.Column`
that is also a primary key column.  Previously, a check for primary key
columns declared on a single-inheritance subclass would occur before the
column copy were allowed to pass.

Accommodate for classically mapped base classes in declarative

2018-08-17T17:42:02+00:00

Fixed issue in previously untested use case, allowing a declarative mapped
class to inherit from a classically-mapped class outside of the declarative
base, including that it accommodates for unmapped intermediate classes. An
unmapped intermediate class may specify ``__abstract__``, which is now
interpreted correctly, or the intermediate class can remain unmarked, and
the classically mapped base class will be detected within the hierarchy
regardless. In order to anticipate existing scenarios which may be mixing
in classical mappings into existing declarative hierarchies, an error is
now raised if multiple mapped bases are detected for a given class.

Filter attributes we don't map during a load_scalar_attributes

2017-10-28T17:29:48+00:00

Fixed bug where a descriptor that is elsewhere a mapped column
or relationship within a hierarchy based on :class:`.AbstractConcreteBase`
would be referred towards during a refresh operation, causing an error
as the attribute is not mapped as a mapper property.
A similar issue can arise for other attributes like the "type" column
added by :class:`.AbstractConcreteBase` if the class fails to include
"concrete=True" in its mapper, however the check here should also
prevent that scenario from causing a problem.

Union the exclude_properties of the inheriting mapper in declarative

2017-01-30T22:28:22+00:00

Fixed bug where the "automatic exclude" feature of declarative that
ensures a column local to a single table inheritance subclass does
not appear as an attribute on other derivations of the base would
not take effect for multiple levels of subclassing from the base.

Repair foreign_keys population for Join._refresh_for_new_column

2016-09-15T04:54:15+00:00

Fixed bug where setting up a single-table inh subclass of a joined-table
subclass which included an extra column would corrupt the foreign keys
collection of the mapped table, thereby interfering with the
initialization of relationships.

Fixes: #3797

- Fixed bug in :class:`.AbstractConcreteBase` extension where

2015-07-13T19:39:04+00:00

a column setup on the ABC base which had a different attribute
name vs. column name would not be correctly mapped on the final
base class.   The failure on 0.9 would be silent whereas on
1.0 it raised an ArgumentError, so may not have been noticed
prior to 1.0.
fixes #3480

- Fixed regression regarding the declarative ``__declare_first__``

2015-04-24T17:49:09+00:00

and ``__declare_last__`` accessors where these would no longer be
called on the superclass of the declarative base.
