heres the latest.... 0.2.6 - big overhaul to schema to allow truly composite primary and foreign key constraints, via new ForeignKeyConstraint and PrimaryKeyConstraint objects. Existing methods of primary/foreign key creation have not been changed but use these new objects behind the scenes. table creation and reflection is now more table oriented rather than column oriented. [ticket:76] - overhaul to MapperExtension calling scheme, wasnt working very well previously - tweaks to ActiveMapper, supports self-referential relationships - slight rearrangement to objectstore (in activemapper/threadlocal) so that the SessionContext is referenced by '.context' instead of subclassed directly. - activemapper will use threadlocal's objectstore if the mod is activated when activemapper is imported - small fix to URL regexp to allow filenames with '@' in them - fixes to Session expunge/update/etc...needs more cleanup. - select_table mappers *still* werent always compiling - fixed up Boolean datatype - added count()/count_by() to list of methods proxied by assignmapper; this also adds them to activemapper - connection exceptions wrapped in DBAPIError - ActiveMapper now supports autoloading column definitions from the database if you supply a __autoload__ = True attribute in your mapping inner-class. Currently this does not support reflecting any relationships. - deferred column load could screw up the connection status in a flush() under some circumstances, this was fixed - expunge() was not working with cascade, fixed. - potential endless loop in cascading operations fixed. - added "synonym()" function, applied to properties to have a propname the same as another, for the purposes of overriding props and allowing the original propname to be accessible in select_by(). - fix to typing in clause construction which specifically helps type issues with polymorphic_union (CAST/ColumnClause propigates its type to proxy columns) - mapper compilation work ongoing, someday it'll work....moved around the initialization of MapperProperty objects to be after all mappers are created to better handle circular compilations. do_init() method is called on all properties now which are more aware of their "inherited" status if so. - eager loads explicitly disallowed on self-referential relationships, or relationships to an inheriting mapper (which is also self-referential) - reduced bind param size in query._get to appease the picky oracle [ticket:244] - added 'checkfirst' argument to table.create()/table.drop(), as well as table.exists() [ticket:234] - some other ongoing fixes to inheritance [ticket:245]
