Deprecate FromClause.count()

2016-06-14T15:48:04+00:00

count() here is misleading in that it not only
counts from an arbitrary column in the table, it also
does not make accommodations for DISTINCT, JOIN, etc.
as the ORM-level function does.  Core should not be
attempting to provide a function like this.

Check for duplicate calls to register_attribute_impl

2016-05-10T15:05:30+00:00

Fixed bug whereby the event listeners used for backrefs could
be inadvertently applied multiple times, when using a deep class
inheritance hierarchy in conjunction with mutiple mapper configuration
steps.

Deprecate Mapper.order_by

2016-04-19T22:17:45+00:00

This is an old parameter no longer relevant to how SQLAlchemy
works, once the Query object was introduced.  By deprecating it
we establish that we aren't supporting non-working use cases
and that we encourage applications to move off of the use of this
parameter.

Add raise/raiseload relationship loading strategy

Fixes: #3512

Pull-request: https://github.com/zzzeek/sqlalchemy/pull/193

- Fixed 1.0 regression where the "noload" loader strategy would fail

2015-08-11T17:05:17+00:00

to function for a many-to-one relationship.  The loader used an
API to place "None" into the dictionary which no longer actually
writes a value; this is a side effect of :ticket:`3061`.
- remove InstanceState._initialize() totally, it's used nowhere
else and no longer does what it says it does
- fill in fowards-port version ids throughout the changes for 1.0.9

- pep8 test/orm/test_mapper

warn on duplicate polymorphic_identity

2014-12-04T13:34:08+00:00

- add an order_by here

2014-11-26T15:34:46+00:00

- The ``info`` parameter has been added to the constructor for

2014-08-13T23:45:34+00:00

:class:`.SynonymProperty` and :class:`.ComparableProperty`.
- The ``info`` parameter has been added as a constructor argument
to all schema constructs including :class:`.MetaData`,
:class:`.Index`, :class:`.ForeignKey`, :class:`.ForeignKeyConstraint`,
:class:`.UniqueConstraint`, :class:`.PrimaryKeyConstraint`,
:class:`.CheckConstraint`.

fixes #2963

- Additional checks have been added for the case where an inheriting

2014-06-20T22:47:28+00:00

mapper is implicitly combining one of its column-based attributes
with that of the parent, where those columns normally don't necessarily
share the same value.  This is an extension of an existing check that
was added via :ticket:`1892`; however this new check emits only a
warning, instead of an exception, to allow for applications that may
be relying upon the existing behavior.
fixes #3042
