* this definitely has to go - theres bugs in merge(), serialization whichMike Bayer2010-01-101-176/+0
| | | | | prevent it from being useful. will have a much more comprehensive example in 0.6.
* new example - apply Beaker caching to a relation().Mike Bayer2010-01-081-0/+176

* - Fixed a slight inaccuracy in the sharding example.Mike Bayer2009-10-251-1/+7
| | | | | | Comparing equivalence of columns in the ORM is best accomplished using col1.shares_lineage(col2). [ticket:1491]
* Added in Examples into the test suite so they get exercised regularly. ↵Michael Trier2009-07-2720-3/+14
| | | | Cleaned up some deprecation warnings in the examples.

* Lots of fixes to the code examples to specify imports explicitly.Michael Trier2009-03-3124-133/+147
| | | | | | | Explicit imports make it easier for users to understand the examples. Additionally a lot of the examples were fixed to work with the changes in the 0.5.x code base. One small correction to the Case expression. Thanks a bunch to Adam Lowry! Fixes #717.
* - Added "post_configure_attribute" method to InstrumentationManager,Mike Bayer2009-02-111-2/+1
| | | | | so that the "listen_for_events.py" example works again. [ticket:1314]
* - sqlalchemy.sql.expression.Function is now a publicMike Bayer2009-01-021-43/+118
| | | | | | | class. It can be subclassed to provide user-defined SQL functions in an imperative style, including with pre-established behaviors. The postgis.py example illustrates one usage of this.
* - Custom comparator classes used in conjunction withMike Bayer2009-01-021-10/+3
| | | | | | | | | | column_property(), relation() etc. can define new comparison methods on the Comparator, which will become available via __getattr__() on the InstrumentedAttribute. In the case of synonym() or comparable_property(), attributes are resolved first on the user-defined descriptor, then on the user-defined comparator.
* - added an extremely basic illustration of a PostGISMike Bayer2008-12-301-0/+230
| | | | integration to the examples folder.
* - Improved the behavior of aliased() objects such that they moreMike Bayer2008-11-031-3/+2
| | | | | | | | | | | accurately adapt the expressions generated, which helps particularly with self-referential comparisons. [ticket:1171] - Fixed bug involving primaryjoin/secondaryjoin conditions constructed from class-bound attributes (as often occurs when using declarative), which later would be inappropriately aliased by Query, particularly with the various EXISTS based comparators.

* - column_property(), composite_property(), and relation() nowMike Bayer2008-09-022-118/+2
| | | | | | | | | | accept a single or list of AttributeExtensions using the "extension" keyword argument. - Added a Validator AttributeExtension, as well as a @validates decorator which is used in a similar fashion as @reconstructor, and marks a method as validating one or more mapped attributes. - removed validate_attributes example, the new methodology replaces it
* - AttributeListener has been refined such that the eventMike Bayer2008-09-022-2/+121
| | | | | | | | | | | | is fired before the mutation actually occurs. Addtionally, the append() and set() methods must now return the given value, which is used as the value to be used in the mutation operation. This allows creation of validating AttributeListeners which raise before the action actually occurs, and which can change the given value into something else before its used. A new example "validate_attributes.py" shows one such recipe for doing this. AttributeListener helper functions are also on the way.
* - add an example illustrating attribute event reception.Mike Bayer2008-08-291-0/+83

| | | | | | - Fixed query.join() when used in conjunction with a columns-only clause and an SQL-expression ON clause in the join.
* - Query.UpdateDeleteTest.test_delete_fallback fails on mysql due to subquery ↵Mike Bayer2008-06-091-9/+1
| | | | | | | | | | | | | | | | | in DELETE; not sure how to do this exact operation in MySQL - added query_cls keyword argument to sessionmaker(); allows user-defined Query subclasses to be generated by query(). - added @attributes.on_reconstitute decorator, MapperExtension.on_reconstitute, both receieve 'on_load' attribute event allowing non-__init__ dependent instance initialization routines. - push memusage to the top to avoid pointless heisenbugs - renamed '_foostate'/'_fooclass_manager' to '_sa_instance_state'/'_sa_class_manager' - removed legacy instance ORM state accessors - query._get() will use _remove_newly_deleted instead of expunge() on ObjectDeleted, so that transaction rollback restores the previous state - removed MapperExtension.get(); replaced by a user-defined Query subclass - removed needless **kwargs from query.get() - removed Session.get(cls, id); this is redundant against Session.query(cls).get(id) - removed Query.load() and Session.load(); the use case for this method has never been clear, and the same functionality is available in more explicit ways

* - fixes to ShardedSession to work with deferred columns [ticket:771].Mike Bayer2007-09-081-1/+2
| | | | | | | - user-defined shard_chooser() function must accept "clause=None" argument; this is the ClauseElement passed to session.execute(statement) and can be used to determine correct shard id (since execute() doesn't take an instance)
* - got all examples workingMike Bayer2007-09-015-13/+29
