* Check for __clause_element__() in ORM insert/updateMike Bayer2016-10-051-1/+1
| | | | | | | | | | | | | | | | 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. Change-Id: I9e15b3f1c4883fd3909acbf7dc81d034c6e3ce1d Fixes: #3802
* Propagate hybrid properties / infoMike Bayer2016-04-181-1/+12
| | | | | | | | | | | 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 docstringsMike Bayer2016-04-181-5/+25
| | | | | | | | | | | | 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. Fixes: #3653 Change-Id: I02549977fe8b2a051802eed7b00cc532fbc214e3 Pull-request: https://github.com/zzzeek/sqlalchemy/pull/239

* Extended the :doc:`/core/inspection` system so that all Python descriptorsMike Bayer2012-12-291-2/+33
| | | | | | | | associated with the ORM or its extensions can be retrieved. This fulfills the common request of being able to inspect all :class:`.QueryableAttribute` descriptors in addition to extension types such as :class:`.hybrid_property` and :class:`.AssociationProxy`. See :attr:`.Mapper.all_orm_descriptors`.

* - express most of the orm.util functions in terms of the inspection systemMike Bayer2012-07-161-96/+96
| | | | | | | | | | | | | | - modify inspection system: 1. raise a new exception for any case where the inspection context can't be returned. this supersedes the "not mapped" errors. 2. don't configure mappers on a mapper inspection. this allows the inspectors to be used during mapper config time. instead, the mapper configures on "with_polymorphic_selectable" now, which is needed for all queries - add a bunch of new "is_XYZ" attributes to inspectors - finish making the name change of "compile" -> "configure", for some reason this was only done partially

* - [feature] Added an example to the hybrid docsMike Bayer2011-12-051-0/+134
| | | | | | | | | of a "transformer" - a hybrid that returns a query-transforming callable in combination with a custom comparator. Uses a new method on Query called with_transformation(). The use case here is fairly experimental, but only adds one line of code to Query.

* - rework setup.py script to work with:Mike Bayer2011-04-171-3/+3
| | | | | | | | | | - Python 3 - Python 3 builds if Distribute isn't installed - rework install documentation again - raise if doc build with mako < 0.4.1 - Python 3.1 builds force doctest parse but then fails due to distribute bug, so remove usage of backslash \\ in hybrid.py docstring - put in the latest ez_setup.py

* - Session.connection(), Session.execute() accept 'bind',Mike Bayer2011-01-181-2/+2
| | | | | | | | to allow execute/connection operations to participate in the open transaction of an engine explicitly. [ticket:1996] - fix up the docs for connection, execute, which were awful. - correct usage strings in hybrid
* - tests for hybridMike Bayer2011-01-171-12/+309
| | | | | - documentation for hybrid - rewrite descriptor, synonym, comparable_property documentation
* - rename hybrid.property_, hybrid.method to hybrid_property, hybrid_method. ↵Mike Bayer2011-01-121-7/+7
| | | | | | | more typing on the import but this is just clearer. - adapt dictlike-polymorphic.py to use hybrid.

* - at long last have gotten the "proxy_property" keywordMike Bayer2010-08-061-4/+7
| | | | | | | | arg of register_descriptor to not be needed. synonym, comparable, concreteinherited props now supply a descriptor directly in the class dict, whose __get__(None, cls) supplies a QueryableAttribute. The basic idea is that the hybrid prop can be used for this. Payoff here is arguable, except that hybrid can be at the base of future synonym/comparable operations.
* - add hybrid extensionMike Bayer2010-08-061-0/+111
- mapper begins to lose awareness of SynonynmProperty, ComparableProperty
