* mapper will verify class inheritance scheme; also will not re-init inherited ↵Mike Bayer2006-04-182-1/+4
| | | | | | property, as the improved attribute system seems to handle inheritance OK and allows the property to keep its correct initialization on the parent exceptions import in query

|
* split up Session into Session/LegacySession, added some new constructor argsMike Bayer2006-04-062-98/+116
| | | | | | | | created AbstractEngine class which provides base for SQLEngine and will also provide base for ConnectionProxy, so SQL binding can be to an engine or specific connection resource ClauseElements get using() method which can take AbstractEngines for execution made more separation between SchemaItems and bound engine
* mapper's querying facilities migrated to new query.Query() object, which can ↵Mike Bayer2006-04-065-303/+397
| | | | | | | | | receive session-specific context via the mapper.using() statement. reuslting object instances will be bound to this session, but query execution still handled by the SQLEngines implicit in the mapper's Table objects. session now propigates to the unitofwork UOWTransaction object, as well as mapper's save_obj/delete_obj via the UOWTransaction it receives. UOWTransaction explicitly calls the Session for the engine corresponding to each Mapper in the flush operation, although the Session does not yet affect the choice of engines used, and mapper save/delete is still using the Table's implicit SQLEngine. changed internal unitofwork commit() method to be called flush(). removed all references to 'engine' from mapper module, including adding insert/update specific SQLEngine methods such as last_inserted_ids, last_inserted_params, etc. to the returned ResultProxy so that Mapper need not know which SQLEngine was used for the execute. changes to unit tests, SelectResults to support the new Query object.
* added explicit "session" argument to get(), select_whereclause in mapper, as ↵Mike Bayer2006-04-062-38/+46
| | | | well as throughout the call-chain for those. lazy loader honors the "session" of the parent object, + added simple unit test
* added 'entity_name' keyword argument to mapper. a mapper is now associated ↵Mike Bayer2006-04-033-60/+77
| | | | | | | | with a class via the class object as well as the optional entity_name parameter, which is a string defaulting to None. any number of primary mappers can be created for a class, qualified by the entity name. instances of those classes will issue all of their load and save operations through their entity_name-qualified mapper, and maintain separate identity from an otherwise equilvalent object.
* attributes overhaul #2 - attribute manager now tracks class-level ↵Mike Bayer2006-04-031-2/+2
| | | | initializers strictly through the SmartPropery instances attached to the class, so that attributes retain their natural polymorphic behavior. naming conventions migrating to "managed_attribute", simplifying codepaths.
* made order_by/group_by construction a little more simplisitcMike Bayer2006-04-031-1/+1
| | | | | fix to mapper extension CompoundSelect can export all columns now, not sure if theres any advantage there
* added unit test for the old commit that was in [changeset:1186]. modified ↵Mike Bayer2006-03-312-9/+10
| | | | its behavior a bit to not delete private relationships unless they were already marked as deleted at the attribute manipulation level. got "switching" behavior from one private relationship to another to work, added a unit test for that.

* tweak to mapper to allow inheritance on the same table.Mike Bayer2006-03-271-15/+17
|
* backrefs on cyclical relationships were breaking for the "root" node which ↵Mike Bayer2006-03-272-0/+7
| | | | had None for a parent, due to addition in [changeset:1186] which added a "deletion" traversal for many-to-one relationships. added unittest.
* added always_refresh flag. when the mapper loads rows, it will pull objects ↵Mike Bayer2006-03-261-1/+5
| | | | from the identity map normally, but always blows away their attributes and replaces with those from the database, including changes
* rework to expire() to make it smarter. when you expire(), history is ↵Mike Bayer2006-03-263-5/+25
| | | | immediately removed as well as explicit from dirty/deleted lists. this also changes uow.rollback_object() to remove from those lists, which is strange that it didnt do that before. anyway the mapper, when selecting and creating instances, asks the uow if this already identity-mapped instance is expired, and if so refreshes it on the fly, saving the need for the re-_get() operation, if some other query happens to touch upon the expired object. unit test added to confirm this.
* column label generation checks for a conflict against a column named the ↵Mike Bayer2006-03-261-2/+2

* improved translation of rows when proxying rows from one mapper to another.Mike Bayer2006-03-261-8/+16
|
* util: the __setitem__ method on historyarraylist was meaningless, surprising ↵Mike Bayer2006-03-261-4/+0
| | | | | | | | nobody noticed that. types: added PickleType, its slightly trickier than trivial, so OK now its standard. attributes: the level of pain if an AttributeError occurs inside a CallableProp, in combination with an object that implements __getattr__, is too deep for me to put the users through....so convert AttributeErrors to Assertions... engine: im not a fan of catching universal exceptions and squashing them

| | | | | | | | column._label, to take advantage of column labeling rules bind param compilation,when it unique-ifys the name of bind params, maintains the length of the bind parameter name instead of appending to it
