Support hybrids/composites with bulk updates

2017-03-22T21:44:56+00:00

The :meth:`.Query.update` method can now accommodate both
hybrid attributes as well as composite attributes as a source
of the key to be placed in the SET clause.   For hybrids, an
additional decorator :meth:`.hybrid_property.update_expression`
is supplied for which the user supplies a tuple-returning function.

Allow reuse of hybrid_property across subclasses

2017-03-21T19:42:42+00:00

The :class:`sqlalchemy.ext.hybrid.hybrid_property` class now supports
calling mutators like ``@setter``, ``@expression`` etc. multiple times
across subclasses, and now provides a ``@getter`` mutator, so that
a particular hybrid can be repurposed across subclasses or other
classes.  This now matches the behavior of ``@property`` in standard
Python.

Support python3.6

Corrects some warnings and adds tox config.  Adds DeprecationWarning
to the error category.   Large sweep for string literals w/ backslashes
as this is common in docstrings

Check for __clause_element__() in ORM insert/update

2016-10-05T16:11:53+00:00

ORM attributes can now be assigned any object that is has a
``__clause_element__()`` attribute, which will result in inline
SQL the way any :class:`.ClauseElement` class does.  This covers other
mapped attributes not otherwise transformed by further expression
constructs.

As part of this, it was considered that we could add
__clause_element__() to ClauseElement, however this causes endless loops
in a "while" pattern and this pattern has been identified in third
party libraries.  Add a test to ensure we never make that change.

Propagate hybrid properties / info

2016-04-18T20:20:20+00:00

Keystone and others depend on the .property attribute being
"mirrored" when a @hybrid_property is linked directly to a
mapped attribute.  Restore this linkage and also create a defined
behavior for the .info dictionary; it is that of the hybrid itself.
Add this behavioral change to the migration notes.

Honor hybrid property / method docstrings

2016-04-18T16:55:48+00:00

The docstring specified on a hybrid property or method is now honored
at the class level, allowing it to work with tools like Sphinx
autodoc.  The mechanics here necessarily involve some wrapping of
expressions to occur for hybrid properties, which may cause them
to appear differently using introspection.
